(a)

  1. Electronic configuration. La3+ → [Xe] 4f0 and Lu3+ → [Xe] 4f14
    Since in both of these ions there is no unpaired electron, so they do not show any colour in the solution.
  2. Due to comparable energy of 5f, 6d and 7s orbitals, there is more irregularity in electronic configuration of actinoids.
  3. In transition elements, electrons are filled in the same atomic orbital which has the poor shielding effect and hence there is not much difference in properies in a series. On the other hand, there is all together different properties of main group elements due to lack of d-orbitals, multiple bond formation, different bond enthalpy etc.

(b) Reactions involved in the preparation of KMnO4 :
CBSE Sample Papers for Class 12 Chemistry Paper 7 Q.24.1
OR
(a) Comparison of Lanthanoids and Actinoids:

  1. Atomic size : Atomic size of both the series decreases from left to right but decrease is more in case of actinoids from element to element due to poorer shielding effect of 5if electrons.
  2. Oxidation state : Lanthanoids show +3 as general oxidation state except +2(Eu, Yb) and +4 (Ce etc.) for some elements. But actinoids show variable oxidation state from +3 to +7, (Although +3 and +4 are most common).
  3. Chemical reactivity : Actinoids are more reactive than lanthanoids due to bigger atomic size and lower ionisation energy as well as comparable energy of 5f, 6d and 7s orbitals, variable oxidation is also responsible for their more reactivity.

(b) Preparation of K2Cr2O7 :
Step I: Chromite ore is mixed with Na2CO3 and heated to melt as O2 gas is passed to give sodium chromate

CBSE Sample Papers for Class 12 Chemistry Paper 7 Q.25.1

(b) Non stoichiometric defects are of two types, depending upon whether positive or negative ions are in excess. These defects are known as:

  1. metal excess defect;
  2. metal deficiency defect

1. Metal excess defect : When negative ion is missing from its lattice site and creates a hole which is occupied by the electron to maintain the electrical neutrality, e.g. NaCl crystals , turns yellow if excess of Na is present.
2. Metal deficiency defect : In many solids due to variable oxidation state it is difficult to prepare them in pure state and as a result there is a metal deficiency, e.g. due to Fe+2 and Fe3+ state of iron, there are always chances of formation of compounds like Fe0.95O, Fe0.98O etc.
OR

(a) Intrinsic and extrinsic semiconductors : Pure substances like silicon and germanium shows an increase in electrical conductivity with increase in temperature and they are called intrinsic semiconductors.
On the other hand small quantity of arsenic boron, etc. when introduced in substances like silicon, germanium the conductivity of the substance is significantly increased and such substances are known as extrinsic semiconductors. These are the two types: n-type and p-type semiconductors.

(b) In TlCl3, Tl3+ ions are there, to accomodate such ions in KCl lattice three K+ ions needs to be replaced for electrical neutrality. It means there will be two vacancies for each Tl3+ ion. Hence for
5 × 10-2 mol % TlCl3 doping → 2 × 5 × 10-2 cation vacancies will be generated.
Concentration of cation Vacancies = 2 × \(\frac { { 5\times 10 }^{ -2 } }{ 100 } \) × 6.002 × 1023 = 6.022 × 1020

Answer 26.

Answer 14.

  • Lyophilic colloids : In these, there are attracting forces acting between particles of dispersion medium and dispersed phase and hence these are known as lyophilic colloids. These are reversible in nature.
  • Lyphobic Colloids : There is no interaction or have very little interactions between the particles of dispersed phase and dispersion medium, i.e. these are solvent repelling colloids. Hence they known lyophobic colloids and they are irreversible in nature.
    Example of Lyophilic colloids -Starch sol, gum, gelatine.
    Lyophilic colloids -Arsenic sulphide sol, Au sol, sulphur sol etc.
    Lyophobic sols can easily get coagulated.
  • Reason : Due to very less interactions between dispersed phase and dispersion medium, coagulation takes place easily.

(b) In vapour phase, sulphur exists as S2 molecule like O2 and posses impaired electrons in antibonding molecular orbitals (π*3Px and π*3Py).
(c) There is weak vander wall’s forces exist among noble gas molecules, hence they have low boiling points.

Answer 22.

  1. There is more +I-effect from the two alkyl group of ketones, hence carboxyl carbon has less positive charge and so it will be less reactive than an aldehyde.
  2. Phenoxide ion has more number of resonating structures but the negative charge lies on less electronegative carbon atoms, hence contribution of such structures is negligible as compared to the resonating structure of carboxylate ion where negative charge lies on the oxygen atom. So the contribution of resonance structures is much more in case of carboxylate ion.
  3. Esterification reaction is a reversible reaction, hence ester is distilled off as soon as it is formed.

    1. MnO4 + I \(\underrightarrow { { OH }^{ – } } \) MnO2 + IO3
    2. NO2 + MnO4 + H+ → NO3 + Mn2+
    3. Cr2O2-7 + Fe2+ + H+ → Cr3+ + Fe3+ + H2O

OR

  1. La2Ois ionic because ‘La’ has largest atomic size and largest ionisation enthalpy among the lanthanoids, whereas Lu2O3 is covalent because Lu has smaller size and higher ionisation enthalpy.
  2. As the size decreases from La to Lu, therefore the stability of oxo-cations also decreases.
  3. The stability of complexes increases as the size of lanthanoids decreases.
  4. Radii of 4d and 5d elements are almost same due to lanthanoid contraction.
  5. Acidic character of oxides of lanthanoids increases from La to Lu because metallic character decreases due to decrease in atomic size and increase in ionisation enthalpy.

(a) Two main types of semiconductors are:
(i) n-type semiconductor
(ii) p-type semiconductor
n-type semiconductors are formed when an element of higher valency is doped in element of lower valency, e.g. Si is doped with Arsenic (As). The extra electron not involved in covalent bond formation increases the conductivity of doped element, p-type semiconductors are formed when element of higher valency is doped with element of lower valency, e.g. Si is doped with Gallium (Ga). It leads to the formation of holes or electron vacancy in doped element.

Conduction mechanism :
n-type semiconductors-Conduction is due to delocalisation of free electrons in the element lattice.
p-type semiconductors-Conduction is due to movement of holes in doped element lattice.
(b) From the given information
Molar mass (M) = 2.7 × 10-2 g mol-1 = 27 g/mol

Answer 6.
For 100 molecules of Fe0.93 O1.00 there will be 93 Fe atoms and 100 oxygen atoms
If Fe2+ ions are x then
Fe3+ ions = 93 – x
Total charge on x ions of Fe2+ and (93 – x) ions of Fe3+ will be equal to 200, i.e. the charge on 100 O2- ions.
Hence 2x + 3(93 – x) = 200
x = 79, i.e. Fe2+ ions = 79 and Fe3+ ions = 93 – 79 = 14.
% of Fe2+ ion = \(\frac { 79 }{ 93 }\) × 100 = 85%
% of Fe3+ ion = \(\frac { 14 }{ 93 }\) × 100 = 15%

  • CaCO3 \(\underrightarrow { heat } \) CaO + CO2
  • C + CO2 → 2CO
  • FeO + CO → Fe + CO2
  • CaO + SiO2 → CaSiO3

Reactions taking place at lower temperature zone (500 – 800 K):

  • Fe2O3 + CO → Fe3O4 + Fe3O4 + CO2
  • Fe3O4 + CO → Fe + CO2
  • Fe2O3 + CO → FeO + CO2

Answer 9.

  1. 2MnO4 + 5H2S + 6H+ → 2Mn2+ + 5S + 8H2O
  2. Cr2O2-7 + 3NO2 + 8H+ → 2Cr3+ + 3NO3 + 4H2O

“It is impossible to think about the welfare of the world unless the condition of women is improved. It is impossible for a bird to fly on only one wing.” — Swami Vivekananda

1. Women are not born, but made. What is better than India to exemplify this statement by Simone de Beauvoir. With the whole world celebrating International Women’s Day with great pomp and show, it would be only apt to analyze the position and space Indian women occupy today, and comparing it to the times 60 years ago when the country had just gained independence. With the women participating in nationalist movements to being pushed into the domestic household space, to their resurgence as the super-women today, women in our country have seen it all.

2. There have been innumerable debates about gender in India over the years. Much of it includes women’s position in society, their education, health, economic position, gender equality, etc. What one can conclude from such discussions is that women have always held a certain paradoxical position in our developing country. On the one hand, the country has seen an increased percentage of literacy among women, and women are allowed to enter into professional fields, while on the other hand the practices of female infanticide, poor health conditions and lack of education still persist. Even the patriarchal ideology of the home being women’s real domain and marriage being her ultimate destiny hasn’t changed much. The matrimonial advertisements, demanding girls of the same caste, with fair skin and slim figure, or the much criticized fair and lovely ads, are indicators of the slow changing social mores. If one looks at the status of women then and now, one has to look at two sides of the coin; one side which is promising, and one side which is bleak.

3. When our country got its independence, the participation of women nationalists was widely acknowledged. When the Indian Constitution was formulated, it granted equal= rights to women, considering them legal citizens of the country and as an equal to men in terms of freedom and opportunity. The sex ratio of women at that time was slightly better than what it is today, standing at 945 females per 1000 males. Yet the conditions of women screamed a different reality.

4. They were relegated to their households, and made to submit to the male-dominated society, as has always been prevalent in our country. Indian women, who fought as an equal to men in the nationalist struggle, were not given that free public space anymore. They became homemakers, and were mainly meant to build a strong home to support their men who were to build the new independent country. Women were reduced to being secondary citizens. The national female literacy rate was an alarmingly low 8.9 per cent. The Gross Enrolment Ratio (GER) for girls was 24.8 per cent at primary level and 4.6 per cent at the upper primary level (in the 11-14 years age group). There existed insoluble social and cultural barriers to education of women and access to organized schooling.

Question 2.
Read the following passage carefully. (10 Marks)

1. One day Pahom was sitting at home, when a peasant passing through the village, happened to call in. He was allowed to stay at the night, and supper was given to him. Pahom had a talk with this peasant and asked him where he came from. The stranger answered that he came from beyond the Volga, where he had been working. One word led to another, and the man went on to say that many people were settling in those parts. He told how some people from his village had settled there. They had joined the Commune, and had twenty-five acres of land per man granted. The land was so good, he said, that the rye sown on it grew as high as a horse, and so thick that five cuts of a sickle made a sheaf. One peasant, he said, had brought nothing with him but his bare hands, and now he had six horses and two cows. Pahom’s heart kindled with desire. He thought:

2. “Why should I suffer in this narrow hole, if one can live so elsewhere? I will sell my land and my homestead here, and with the money I will start afresh over there and get everything new. In this crowded place one is always having trouble. But I must first go and find out all about it myself.”

3. Towards summer he got ready and started. He went down the Volga on a steamer to Samara, then walked another three hundred miles on foot, and at last reached the place. It was just as the stranger had said. The peasants had plenty of land: every man had twenty-five acres of Communal land given him for his use, and any one who had money could buy, besides, at fifty-cents an acre as much freehold land as he wanted. Having found out all he wished to know, Pahom returned home as autumn came on, and began selling off his belongings. He sold his land at a profit, sold his homestead and all his cattle, and withdrew from membership of the Commune. He only waited till the spring, and then started with his family for the new settlement.

4. As soon as Pahom and his family arrived at their new abode, he applied for admission into the Commune of a large village. He stood treat to the Elders, and obtained the necessary documents. Five shares of Communal land were given him for his own and his sons’ use: that is to say-125 acres (not altogether, but in different fields) besides the use of the Communal pasture. Pahom put up the buildings he needed, and bought cattle. Of the Communal land alone he had three times as much as at his former home, and the land was good corn-land. He was ten times better off than he had been. He had plenty of arable land and pasturage, and could keep as many head of cattle as he liked.

Question 3.
Read the following passage carefully. (8 Marks)

Ayurveda is one of the oldest sciences of medicines whose origin can be dated back to 3000-5000 years.

Ayurveda is a method of holistic healing and is based on prevention rather than cure of the illness. The approach to healing is done on a personalized basis and people of all ages and following different occupations are known to have benefited both personally and spiritually owing to Ayurveda’s wisdom of healing.

Ayurvedic medicines heal your spirit and minds instead of just treating the affected body parts. It is based on purification of the body in a natural way and the environment created helps remove all toxins and help regain body’s natural tolerance or resistance from the diseases and help rejuvenate your body and regain your good health.

The metaphysics of the five elements that make up this universe namely: earth (prithvi), water (jal), fire (agni), air (vayu) and space (akash) form the basis of the science of Ayurveda. Ayurveda explains the constitution of human to be of three forms which are known as ‘doshas’ or the life forces. These three doshas: Vat a, Pitta, Kapha determine physical characteristics and personality traits of a person.

Pitta dosha is believed to control the hormone function and digestion, thus an increased pitta dosha in a person will create indigestion and overheating. Such people will have heated emotional reactions.

Vata dosha controls the heart and breathing functionality in addition to the excretory function. Skin conditions are more common in people suffering from Vata dosha.

Kapha dosha is what governs your immune system and overall strength. Diseases like cancer and diabetes are likely to arise in people with aggravated kapha dosha. An Ayurvedic doctor or practitioner will analyze the dosha based on the systems of your disease or illness and suggest an individualized treatment to heal your body and strengthen your personality.

Vat a dosha is constituted from Ether and air and thus nerve impulses, respiration and elimination are known to be regulated by this dosha. The process of transformation and metabolism is controlled by Pitta dosha which is composed of fire and water. Kapha dosha t contains water and earth elements and is responsible for growth, adding of body structure unit by unit and also offers protection.

Ayurveda has its popularity to the use of natural, non-invasive components used in medicines unlike the other ways of treatment which use only chemicals and toxins into your body.

Ayurveda is not only based on medicines but focuses on lifestyle changes, change in diet patterns, suggesting yogic exercises, and meditation, breathing or relaxation exercises. It is known that certain chronic ailments can be treated by means of Ayurvedic way of natural healing avoiding the need for any surgery. Herbal remedies are also a part of Ayurvedic medicines which can be recommended for healing. Ayurvedic supplements help ‘ pacify one or more increased doshas in your bodies.

Thus, Ayurveda aims at aligning your body, mind and spirit in order to achieve a sound health. Yoga and meditation are known to have a positive impact on your physical condition and help relax your mind and muscles. Ayurveda insists on a spiritual way of living and gives importance to self-realization to bring real health and energy, in whatever tasks we perform. Ayurveda is a rational system of medicine and is sensitive to nature and Earth. Ayurveda has gained popularity in the West also as yoga ashrams and Ayurvedic classes and programmes are being introduced in many parts of the West.

Sub: Appreciation of Delhi Metro

Dear Sir

I recently had my first journey by Delhi Metro Train from Dwarka to Akshardhaam. I wish to put on record the memorable experience that I had of the metro service.

The punctuality and frequency of the trains is commendable. It was heartening to see that Delhi Metro is fully committed towards safety and security of women passengers. Delhi Metro understands the needs of women passengers and has reserved a coach especially for lady passengers. The first coach of a train in moving direction is reserved for ladies. Delhi Metro is perhaps India’s first public transport system with adequate features for 1 differently-abled persons. The spacious, clean and fully air-conditioned interiors make the journey restful and comfortable. In fact I noted so many passengers reading a book or listening to their favourite music.

Security is a high priority with the DMRC as was evident by the scanner and the many police personnel moving about vigilantly at the station.

Facilities like clean toilets, metro card, and lost and found facility have made Delhi Metro a world class facility. I request you to give space to my letter so that it will reach the public and authorities.

Thank you
Yours sincerely
Karan

Answer 6.

Natural Disasters
By Jai Kanta

Natural calamities have been a cause of great destruction and devastation on Earth. Natural calamities are unpredictable in nature and often occur all of a sudden. Due to this nature, avoiding them is almost impossible. However, we can take certain precautions that will help keep the level of devastation down and save precious human lives.

For disasters like floods and landslides, plantation of trees is a good long-term solution. Floods and landslides are hard to avoid. These could include passing of laws that prohibit cutting down of trees and building of houses in regions that are flood prone. Disasters like drought can be avoided by proper planning and allocation of resources. Measures can be taken at community level so that no one is misusing or overusing their share of resources like water and food.

As far as earthquakes are concerned, people should calmly leave the building they are in when the quake strikes. In case of damage, people are encouraged and taught to help pull out other people from the debris. On a larger scale, buildings can be constructed in a way that ensures they are less likely to collapse during an earthquake. In Japan for instance, there are shock absorbers installed at the base of the buildings which enables the building to move with the earthquake and prevent collapse.

The Chief Guest during his address stated “Sports is very important. Everyday children should spare some time for sports.”

Answer 7.
Good morning respected principal, teachers and my dear friends! Today I wish to talk to you about the importance of educating girls. Educated women are capable of bringing socio-economic changes. The constitution of almost all democratic countries, including India, guarantees equal rights to both men and women. Education will empower women to come forward and contribute towards the development and prosperity of the country. So long as women remain backward and economically dependent on men, the helpless condition of them cannot be changed. Education helps a woman to lead a good life. Her identity as an individual would never get lost. She can read and learn about her rights. Educated girls and women are aware of the importance of health and hygiene. Educated mothers can take better care of both herself and her baby.

Educated women are now looked upon with dignity and honor. Educated women are more informed of their rights for justice. It would eventually lead to decline in instances of violence and injustice against women such as dowry, forced-prostitution, child-marriage, female foeticide, etc.

A girl-child should get equal opportunity for education, so that, she can plan to become a successful doctors, engineer, nurse, or choose any other profession of her choice.

Thank you

Good morning, respected Principal, teachers and my dear friends! As you know the Prime Minister’s campaign, ‘Swachh Bharat has become popular throughout India. I wish to take this opportunity to talk to you about the value of cleanliness. Cleanliness is important for healthy mind, body and spirit. Our first duty is to be clean. Every morning, as soon as you get up, you must clean your teeth, and wash your face, hands and feet. Many boys and girls, when they write with ink and pen soil their fingers. With a little care and effort they can avoid it.

If possible, you may bathe and wash your whole body. Bathing is necessary for good health. If you allow dirt to accumulate on your body, you very soon get itch or other diseases of the skin.

After your body, you must look into your clothes. You should always wear clean clothes. Now, do not mistake rich clothes for clean clothes. You do not require any money at all to keep your body clean, and you want very little to keep your clothes tidy. We should get into the habit of being clean.

Besides, we should keep our surroundings clean. We should not throw garbage here and there. Instead, we should throw it only into a dustbin.

Hence, you should always maintain cleanliness and join hands to make ‘Swachh Bharat” campaign a success.

Thank you

Answer 8.

(a) The poet is Stephen Spender.
(b) The children sitting in the elementary classroom of the slum school are like the rootless weeds as they appear malnourished, sad and dispirited.
(c) The phrase ‘paper-seeming’ suggests a thin malnourished boy who is as thin as paper.
(d) Like ‘Rootless weeds,’ the hair torn around their pallor the second line is an example of simile.

OR

(a) The speaker is the daughter, Kamla Das. The speaker is referring to her mother.
(b) The word ‘ashen’ means like ash. The mother appears to be old and grey.
(c) She comes to realize that her mother was not young any longer, and that her appearance had caught up with her age. .
(d) The painful thought of the mother’s death made her determined to focus her attention on something else.

Answer 9.
(a) Sour cream indicates the colour cream or dirty white. The poet has used this expression to describe the poor dull and ill-equipped environment of the classroom in the slums. The walls were painted long ago and since then no attention has been given to them. We see the neglect that these children face. It adds to the dull ambiance.

(b) The contrast between the ageing mother and the merry children enhances the poetic effect. The poet’s mother who is sitting beside her is dozing. Her ‘ashen’ face looks lifeless and pale like a corpse. She is an image of ageing, decay and passivity. On the other hand, the children are gay and happy. They are moving out of their homes in large numbers. Here is an image of happiness and spontaneous overflow of life.

(c) Franz innocently wonders whether the Germans will make the pigeons speak German too. It highlights the foolishness and high-handedness of the Germans who presumed to think that a mere order could make people lose their language. Language is a part of one’s identity. Germans can impose German language on the people of Alsace and Lorraine powerfully but their power cannot make the pigeons speak German.

(d) William’s mother continually warned him against his going to the Yakima River for swimming. The river was treacherous. Many persons had drowned in it. But the YMCA pool was safe. It was only two or three feet at the shallow-end and nine feet at the deeper-end. The slope was also gradual.

(e) The ironmaster of the Ramsjo ironworks watched both night and day that the work at the mills was being done well. On his nightly round for inspection, he saw the ragged fellow, near the furnace. He walked near to him to look closely. Taking him to be his old acquaintance, Nils Olof, he invited him home. It would be pleasant to have him for Christmas. So he spoke kindly to the peddler and invited him home.

(f) Dr. Sadao knew that the wounded American sailor could be arrested anytime. He washed his wound, brought the bullet out of his body and gave a new lease of life to the American prisoner of war. He didn’t want to throw him into the jaws of death again. He asked the young soldier to take his private boat at night. He should row in the cover of darkness to a little deserted island nearby. If he harboured the prisoner longer, he himself could be prone to danger. The general had quite forgotten to help him. So his solution was the best one.

Answer 10.
Dr Sadao and his wife Hana remained in a state of conflict for quite a long time. They couldn’t throw a wounded man again into the sea. If they gave shelter to him in their house, they could be arrested. Handing him over to the police, would have meant throwing him into the jaws of death. They were in a fix. Ultimately, the duty of a doctor overpowered all other petty considerations. The servants revolted at the idea of serving a white man. Hana herself washed the wound. Dr Sadao had decided to operate on Tom.

Hana obeyed her husband without a word. Hana was to give the anaesthetic if the patient needed it. The doctor made a clean and precise incision. The bullet was out. Thus love for humanity and the ethics of a doctor won over petty racial considerations.

The Bible says that one should condemn the sin and not the sinner. Even the worst of criminals have a small core of humanity in their hearts. Prison staff are responsible for the criminals in their custody. Nevertheless, being humans, they often become friendly and lenient towards them often permitting them things which are strictly disallowed according to rules. This is amply supported in the story Evans Tries an O-Level. Evans pleaded with Jackson that he was like a ‘lucky charm’ for him. Jackson relented and allowed Evans to wear his hat on his head. This proved to be a lapse on the part of Jackson as later on Evans used it cleverly to change his appearance.

Answer 11.
Rajkumar Shukla apprised Gandhi about the injustice done to sharecroppers by the landlords in Bihar. He knew the atrocities of the landlord. The sharecroppers were to plant 15 per cent of their holding with indigo and surrender the entire harvest to them as rent. Germany had developed synthetic indigo. Thus the price of the natural indigo would fall in the market sharply. The landlords had obtained agreements from the sharecroppers to pay compensation. Some signed while others engaged lawyers. Gandhi fought against the cruel injustice of the landlord. An official commission declared to refund the money to the sharecroppers. As per agreement 25 per cent of the money was paid to the sharecroppers. This movement encouraged Indian peasants to know their rights. He made the British realise that the Indians are self reliant and the foreigners cannot order them on their land. Thus the Champaran episode was a turning point in his life.

Sophie’s father is a dominating personality. He is a typical representative of the lower middle class family. He is poor but somehow manages to pull on with his family. He lacks refined manners or sophistication. The way he eats the pie exposes his rough eating habits. He tosses one of little Derek’s shoes from his chair on to the sofa. He doesn’t seem to be much interested in the family. Watching football on the television is his favourite pastime. Sophie’s father has passion for football. He is an old admirer of Tom Finny, a great footballer. He adores the upcoming young footballer Casey. So he makes a ‘weekly pilgrimage’ to watch United and Casey in action.

Sophie’s father doesn’t seem to be very sympathetic towards his daughter. But he understands his daughter well. He doesn’t believe in her meeting with Casey. He considers it another of her “wild stories”.

Answer 12.
Kemp is referred to as “the doctor,” but his degree seems to be an academic one rather than a medical one. He continues his own study in the hope of being admitted to “the Royal Fellows.” His own experiments and fascination with science enable him to listen sensibly to Griffin, but in spite of being rather contemptuous of his fellow citizens, his common sense and decency prevent him from being a part of Griffin’s schemes. Kemp is also the only “cool headed” person in the town once the final attack begins. He runs to escape Griffin, but as soon as Griffin catches him, he has the presence of mind to turn the capture around. He is also the first to realize that even though Griffin is invisible, he is injured, and, ultimately, dead. He is a conscientious person in contrast to Griffin who though a genius, is a depraved man.

A symbol is an object that not only demands attention in itself but also refers to another object or to a concept. Often there is no one concept attached to a given object. Instead, a whole range of ideas may be brought into play.

The tale of Silas Marner certainly must be understood symbolically as well as literally. Eppie is cute golden haired toddler when she wanders into Silas’ cottage. Silas is then in the throes of a fit. When he wakes he sees a lock of gold which belongs to Eppie. He adores her and gradually she brings meaning into his life. Eppie is explicitly put forward as a substitute for Silas’ treasure, and this raises questions of the nature of treasures-literal and spiritual. Eppie is a symbol of treasure—a compensation for the real gold that he had lost earlier. Thus she operates at a literal and also symbolic level.

Answer 13.
The theme of corruption in the absence of social law is embodied in the character of Griffin. The narrator uses the invisible man to experiment with the depth to which a person can sink when there are no social restrictions to suppress his behaviour. When Griffin first kills his father, he excuses it by saying that the man was a “sentimental fool”. On the contrary, he resorts to committing atrocities because they are necessary to his survival. The novel also explores the theme of Science without Humanity. The theme is represented in the character of Kemp as well as in Griffin himself. Kemp wants to stop Griffin more out of fear for himself than out of concern for the community, but he is nonetheless fascinated by the accomplishment of this misguided college student. Griffin pursued the idea of invisibility in order to unleash a reign of terror.

Chance and coincidence influence the action in this novel. The novelist, George Eliot has shown how chance and coincidence contribute a lot to the development in the life of the protagonist Silas Marner. The villagers at Lantern Yard arrange draw of lots to pick-up the identity of thief who had stolen the deacon’s money. This is done following an article of their religion. The result of this draw is a matter of chance. Also Eppie’s entry into Silas’ life happens purely by chance. The entry of Eppie the little girl reanimates him. Thus Eppie is the best compensation for his loss of gold. Godfrey’s orders for the stone- pits to the drained of all their waters and the discovery of Dunstan’s skeleton along with Mamer’s lost gold guineas are matter of co-incidence but crucial events and revelations hinge on them.

  • Separate instructions are given with each section and question, wherever necessary. Read these instructions very carefully and follow them faithfully.
  • Do not exceed the prescribed Word limit while answering the questions.

SECTION A
READING (30 MARKS)

Question 1.
Read the following passage carefully. (12 Marks)

1. Pollution has been defined as the addition of any substance or form of energy to the environment at a rate faster than the environment can accommodate its dispersion, breakdown, recycling or storage in some harmless form. In simpler terms, pollution means the poisoning of the environment by man.

2. Pollution has accompanied mankind ever since groups of people settled down in one place for a long time. It was not a serious problem during primitive times when there was more than ample space available for each individual or group’. As the human population boomed, pollution became a major problem and has remained as one ever since. Cities of ancient times were often unhealthy places, fouled by human wastes and debris. Such unsanitary conditions favored the outbreak of diseases that killed or maimed many people living in those times.

3. The rapid advancement of technology and industrialization today is something that man can be proud of. However, it has brought along with it many undesirable results, one of which is the pollution of our environment. Humanity today is threatened by the dangers of air, water, land and noise pollution.

4. The air that we breathe is heavily polluted with toxic gases, chemicals and dust. These consist of the discharge from industrial factories and motor vehicles. The emission of tetraethyl lead and carbon monoxide from exhaust fumes is a major cause for concern too. Outdoor burning of trash and forest fires has also contributed to air pollution. They cause the smarting of the eyes, bouts and coughing and respiratory problems. Owing to the burning of fossil fuels, the level of carbon monoxide in the air is more than desirable. Too high a level of carbon dioxide will cause the Earth’s temperature to rise. The heat will melt the polar caps, thus raising the sea level and causing massive floods around the world. The burning of fuels also produces gases which form acid rain. Acid rain has a damaging effect on water, forest and soil, and is harmful to our health.

5. Man has reached the moon and invented supersonic crafts that can travel faster than the speed of sound. However, these inventions emit pollutants which contribute to the depletion of the ozone layer. This depletion of ozone, which absorbs the harmful rays of the sun and prevents them from reaching the Earth, will have drastic effects on all living things. It will lead to a rise in the number of people suffering from skin cancer.

6. Water pollution has become widespread too. Toxic waste has found its way into our lakes, streams, rivers and oceans. This waste is released by factories and sea-going vessels. Spillage of oil by tankers and during the recent Gulf War has caused irreparable damage to marine life. Thousands of sea animals have died or were poisoned by the pollutants in their natural habitat. As such, it is dangerous for humans to consume sea food caught in polluted waters.

7. Dumping of used cars, cans, bottles, plastic items and all other kinds of waste material is an eyesore. Much of the refuse is not biodegradable and this interferes with the natural breakdown process of converting substances from a harmful form to a non harmful one. As such, it becomes a hazard to one’s health.

8. We are often faced with noises from construction sites, jet planes and traffic jam. we may be unaware of it but noise pollution has been attributed to causing a loss of hearing, mental disturbances and poor performance at work.

9. To control environmental pollution, substances which are hazardous and can destroy life must not be allowed to escape into the environment. This calls for united decision¬making among world leaders and a public awareness of the dangers of pollution.

I. On the basis of your understanding of the passage, answer the following questions by choosing the most appropriate option. (1 × 4 = 4 Marks)

(a) Pollution was not a serious problem in ancient times because:

  1. people were unsettled.
  2. lot of space was available.
  3. population was less.
  4. all of the above.

(b) Acid rain does not cause:

  1. smarting of eyes.
  2. water pollution.
  3. soil pollution.
  4. damage to forest.

(c) The number of people suffering from skin cancer will rise because :

  1. man has invented supersonic aircrafts
  2. ozone layer is depleting.
  3. no efforts are being made to repair the ozone layer.
  4. inventions emit pollutants that deplete the ozone layer which absorbs cancer- causing rays.

(d) If the refuse is not biodegradable it:

  1. becomes an eyesore.
  2. interferes with natural breakdown.
  3. remains a health hazard.
  4. both (ii) and (Hi).

II. Answer the following questions as briefly as possible.

(e) Explain how recycling can help prevent pollution.
(f) Briefly explain what you understand by the term ‘acid rain’.
(g) What are the hazards of exposure to excessive noise?
(h) How can pollution be controlled?
(i) How is marine life under threat?

III. Find words from the passage which mean the same as:

(a) Faster than the speed of sound (para 5)
(b) house or lodge (para 1)
(c) ugly, blot on the landscape (para 7)

Question 2.
Read the following passage carefully. (10 Marks)

1. One of the principal values of travelling is that, it breaks the monotony of life and work. Life, for most people, is a mad rush from one place to another, from one activity to another, trying to gather as much as possible.

2. In this process, people tend to forget, who they are and what they are. There is no time to ponder and wonder. They tend to forget the values of life. Travelling is a time when people relax, reflect and ponder. Most people, after a pleasant travel, return home with a fresh outlook, new zeal and a better determination.

3. Travelling has also a great informative value. It widens the grasp of our knowledge of geography, different cultures and people, etc. For example, when people of Assam visit South India, they learn a great deal. They come to know about the geographical features of South India, such as the existence of numerous rivers, coconut groves, backwaters, spice gardens, rubber plantations, oceans, seas, factories, cities, etc.

4. They also learn many things about the Dravidian culture which characterize the people’s style of living there. They come to know about their mode of living, social life, agriculture, worship, beliefs, art forms, etc. Such a visit is bound to enlighten the visitor and make him/her more appreciative of other cultures.

5. Travelling has a special importance to students. Many of the things they learn in textbooks can be practically understood when they visit various places. When they visit cities, such as, Kolkata, Mumbai, Delhi, etc, or the famous lakes such as Chilka Lake in Odisha, Logtak Lake in Manipur, Dal lake in Kashmir, etc., their grasp of geography is deepened. Visits to industrial centres, such as, Jamshedpur, Kharagpur, Ranchi, Bangalore, Coimbatore, or important places like Cape Comorin, Madurai, Pondicherry, Goa, Kovalam, Cochin, Bhopal, Srinagar, Chandigarh, etc. open their minds beyond their world. Therefore, travelling has a great academic and scholastic value.

6. Another significant value of travelling is that it has the potential to improve one’s health. A visit to places like Nainital, Darjeeling, Shillong, Panchmarhi, Goa, Kovalam, Ooty, etc. can have tremendous effect on our physical and mental health.

7. The beauty and cold of the hills, the charm of the valleys, the chirping of birds, the song of the rivers, the howling of animals, pleasant air, quiet places, etc., can heal many of our mental and physical problems. In the Indian context, travelling and visiting places have another important value that of understanding other’s traditions and cultures.

8. A visit to various parts of India will make us realize that India is a mosaic of cultures, races and creed and that diversity is the chief hallmark of our land. In this context, travelling can help national integration and unity to a great extent.

9. Thus, travelling has tremendous educative, informative and social value. It widens people’s mental horizon, improves health, adds thrill and relaxation to life, dispels boredom and helps promoting national integration. Therefore educational tour should become an integral part of modern education. Travelling also boosts our national economy and the development of tourism industry.

I. Answer the following questions by choosing the most appropriate option: (1 × 2 = 2 Marks)

(a) In the mad rush of life people forget:

  1. Who they are
  2. To wonder and ponder
  3. Forget their values
  4. All of these

(b) The example of Nainital has been given to prove that:

  1. travelling can improve our mental and physical health
  2. travelling is informative
  3. travelling introduces us to different states
  4. travelling has scholastic value

II. Answer the following questions as briefly as possible. (1 × 6 = 6 Marks)

(c) What can be learnt by visiting South India?
(d) How can travelling help students?
(e) How does the charm of the hills impact one’s health?
(f) What does the writer mean by the phrase ‘mosaic of cultures’?
(g) How can travelling promote national integration?
(h) What makes people forget the values of life?

III. Find words from the passage which are similar in meaning to the following.

(a) repetitiveness, boredom (para 1)
(b) tell, explain (para 3)

Question 3.
Read the following passage carefully. (8 Marks)

Although stupidity is commonly defined as ‘a lack of normal intelligence’, stupid behaviour is not the behaviour of a person lacking in intelligence but the behaviour of a person not using good judgement or sense. In fact, stupidity comes from the Latin word that means ‘senseless’. Therefore, stupidity can be defined as the behaviour of a person of normal intelligence who acts in a particular situation as if he or she isn’t very bright. Stupidity exists at three levels of seriousness.

First is the simple, relatively harmless level. Behaviour at this level is often amusing. It is humorous when someone places the food from a fast food restaurant on the roof of the car while unlocking the door and then drives away with the food still on the roof. We call this absent-minded. The person’s good sense or intelligence was temporarily absent. At this level, other than passing inconvenience or embarrassment, no one is injured by the stupid behaviour.

The next type—serious stupidity—is more dangerous. Practical jokes such as putting sugar in the salt shakers are at this level. The intention is humorous, but there is a chance of harm. Irresponsible advice given to others is also serious stupidity. An example is the person who plays psychiatrist on the basis of an introductory psychology course or doing a TV program on psychiatry. The intention may be to help, but if the victim really needs psychiatric help, an amateur will only worsen the situation.

Even worse is the third kind of stupidity. Kind people, who would never injure another living being, stupidly throw away a box of six-week-old kittens along a country road. Lacking the heart to kill the poor things, they sentence them to almost certain death from wild animals, infections, exposure or the wheels of a passing vehicle. Yet they are able to tell themselves that ‘they will find nice homes’ or ‘animals can get along in the wild’. Another example of this kind of stupidity is the successful local businessman who tries to have as many office affairs as he can get away with. He risks the loss  of his business and his home. He fails to see that what he is doing is wrong. This is the true moral stupidity of a person not willing to think about the results of his actions or take responsibility for them. The common defence of a person guilty of stupidity is—‘But I didn’t think ’ This, however, is not a proper excuse, especially when serious or harmful stupidity is involved. (All India (C) 2015)

A. On the basis of your reading of the above passage make notes on it, using headings and sub-headings. Use recognizable abbreviations (wherever necessary—minimum four) and a format you consider suitable. Also supply an appropriate title to it. (5 Marks)
B. Write a summary of the passage in about 80 words. (3 Marks)

Sub: Problem of Begging in India Sir,

I would like to request you to kindly give a little space to my letter in your esteemed newspaper.

The problem of beggars in India is a matter of great shame and concern. Both adults and children are seen at the bus-stop, at red lights, near temples, at market, etc. A beggar is a stigma. He is a burden on society. Begging neither involves physical labour nor mental exertion. Some beggars earn more than most of the low paid persons. They get used to a life of leisure.

Some people deceive others pretending to be handicapped and beg in the name of God. God-fearing and charitable people give them alms. They pose to be deaf and dumb in order to arouse the sentiments of the passerby and evoke their sympathy. They do not spare even foreign tourists and these foreigners get a bad image about our country due to these beggars. They even push their little children into this menace.

It is a sin against humanity to patronize beggars. With our help we are spoiling a person and are creating a problem for the society by adding to the number of beggars. The authorities should put a ban on begging so that the pursuers and perpetrators of begging should be dealt with an iron hand.

Yours faithfully
Mohit

Answer 6.
Good morning, respected Principal, teachers and students! I, Karuna, am here to deliver a speech on the importance of sports and games in one’s life. Games and sports are an integral part of a student’s life. A student should study hard to be successful in competitive examinations. But, he should also play games and sports to enjoy the health and vigour of life.

Along with bookish learning, a student should spend his time on games and sports. There are many people who give importance only to bookish knowledge. Indeed, there is often no provision for games at all. There are many benefits of games and sports in education. Outdoor games such as football, cricket, badminton, tennis, etc. gradually build our personality. It is completely optional for the students to participate in games and sports and as a matter-of-fact very few take part in school or college games. The training for different branches of games and sports should be given in a scientific way under a good coach, according to the ability and interest of the student.

Inclusion of games in the curriculum of studies is, therefore, very important in modern times. Remember, ‘All work and no play makes Jack a dull boy’. ‘

Thank you

Good morning, respected Principal, teachers and students! Today I am going to speak on ‘Hygiene’ as a way of life. It is a habit that needs to be focused on and inculcated in children at an early age. And it need not be restricted to our bodies alone; it needs to be maintained through our diet and surroundings as well. Let’s see how we can go about this.

Do not eat food from roadside stalls. Such roadside food stalls are the main causes of stomach disorders and water-borne diseases. There is no surety of the quality of the materials that they use.Your favourite samosas can give you a terrible stomach ache! A proverb says that health is wealth. It is truly said that of all things in the world, health is the most valuable that one can possess. Money is no doubt a pleasant thing. However, it can give no pleasure to a man of ruined health. As body and mind are closely connected, the mind cannot be sound and cheerful without sound health. Wholesome food gives good health. Vegetables and many other things that we generally take are nutritious food. A mixed diet is the best food for us. Stale and rotten food is dangerous for health. I hope you will adopt healthy eating habits for your good health.

Thank you

College Life
By Navtej

Many young adults seem to believe that college life is filled with parties and typically a laid-back lifestyle. They imagine a lifestyle with no other worries besides occasional tasks. It is often said that college is the greatest time of one’s life; many high school students believe this and look forward to it. Some enjoy the idea of being able to come to class late, leave when they want, and pretty much have say-so of their own lives now that their parents are out of the picture. The majority of freshmen enter college picturing it an easy and fun-filled ride.

College is a very important part of your life because it is going to prepare you mentally and physically for your future. Higher studies equip you with knowledge, skills that give you the required leverage for a fulfilling career. It is the time for greater exposure to a variety of people, and different ideas. It is truly the time for building one’s personality, understanding oneself, exercising independence and realizing one’s potential.

Akash Public Scool Hosts English Debate
By Navita

Agra, 8th September: An Inter house English Debate competition for the juniors (standard IX and X) was held on 7th September, 20xx. The format of the debate was a bit different as the day witnessed the prelims wherein Narmada and Cauvery had to debate on the topic, ‘Does the Present Education System Provide Holistic Education?’ Whereas the other two houses Ganga and Godavari exhibited their debating skills on the topic, ‘RTE: A Boon for the Underprivileged’.

The competition was judged by Mrs. Prabhjot and Mrs. Shanti Sateesh and moderated by Monisha C S and Deeksha Arora. It was very evident that the teams were well prepared and they used various skills like overstatement, definition, irony, etc. to convince the audience. The participants, armed with statistics and data made their arguments more emphatic with their facial expressions, body movement and gestures. All the four teams exhibited great oratorical skills but finally the two teams that were declared winners were Ganga and Narmada. Mrs. Prabhjot said, “The standard of the debate was awesome.” The final will be held shortly and it is expected to be laced with more nail biting moments and an intense face off.

Education brings and prosperity, honour, equality and dignity. Bama was inspired by her elder brother’s words on education. She studied hard and stood first in the class. Then many friends came to her on their own accord. Education is the only tool to end discrimination as it subscribes to the principles of merit and sincerity. It can rise above the considerations of caste, race, creed, religion and gender which have been plaguing our world since time immemorial. Thus it is secular and progressive and open for all.

Superstition is blind belief. It is irrational yet it exists in the human mind in varying degrees. It hampers the progress of society and compels people to commit foolish and dangerous actions. In the story ‘The Tiger King1 the astrologer predicted that the tiger king would be killed by the hundredth tiger.

So the Maharaja began his campaign of tiger-hunting with rare single-mindedness. Within a span of ten years he killed 70 tigers. It was his master strategy to marry a girl of a state which had a large tiger population. So he was able to kill 99 tigers in all.

The tiger king could pay any price to maintain his kingdom. He had to give a bribe worth three lakh rupees to a high ranking British official to retain his kingdom. He could be hot-headed and doubled the tax on the people. It is ironical that the King met his death by a tiger, albeit a wooden one. At last, the hundredth tiger took revenge upon him and the superstition prevailed.
