Read the following passage and answer the questions that follow:The outcasts were not allowed to mount the platform surrounding the well, because if they were ever to draw water from it, the Hindus of the three upper castes would consider the water polluted. Nor were they allowed access to the nearby brook as their use of it would contaminate the stream. They had no well of their own because it cost a lot of money to dig a well in a hilly town. Perforce they had to collect at the foot of the upper-caste Hindu well and depend on the bounty of some of their superiors to pour water into their pitchers.More often than not there was no upper caste Hindu present. Most of them were rich enough to get the water-carriers to supply them with plenty of fresh water every morning for their baths and kitchens, and only those came to the well who were either fond of an open-air bath or too poor to pay for the water-carrier’s services. So the outcasts had to wait for a chance to bring some upper – caste Hindu to the well, for luck to decide that he was kind, for fate to ordain that he had time to get their pitchers filled with water.They crowded around the well, congested the space below its high brick platform, morning, noon and night, joining their hands in servile humility to every passerby; cursing their fate, and bemoaning their lot, if they were refused the help they wanted; praying, beseeching and blessing, if some generous soul condescended to listen to them, or to help them.When Sohini reached the well there were already about ten other outcasts waiting. But there was no one to give them water. She had come as fast as she could to the well, full of fear and anxiety that she would have to wait her turn since she could see from a distance that there was already a crowd. She didn’t feel disappointed so much as depressed to realise that she would be the eleventh to receive water. She had sensed the feeling in her brother’s soul.He was tired. He was thirsty. She had felt like a mother as she issued from her home to fetch water, a mother going out to fetch food and drink for her loved ones at home. Now as she sat in a row with her fellow-sufferers, her heart sank. There was no sign of anyone passing that way who could be a possible benefactor. But she was patient.

Read the following passage and answer the questions that follow:I remember my childhood as being generally happy and can recall experiencing some of the most carefree times of my life. But I can also remember, even more vividly, moments of being deeply frightened. As a child, I was truly terrified of the dark and getting lost. These fears were very real and caused me some extremely uncomfortable moments.Maybe it was the strange way things looked and sounded in my familiar room at night that scared me so much. there was never total darkness, but a street light or passing car lights made clothes hung over a chair take on the shape of an unknown beast.Out of the corner of my eye, I saw curtains move when there was no breeze. A tiny creak in the floor would sound a hundred times louder than in the daylight and my imagination would take over, creating burglars and monsters. Darkness always made me feel helpless. My heart would pound and I would lie very still so that ‘the enemy’ wouldn’t discover me. Another childhood fear of mine was that I would get lost, especially on the way home from school. Every morning, I got on the school bus right near my home – that was no problem.After school, though, when all the buses were lined up along the curve, I was terrified that I would get on the wrong one and be taken to some unfamiliar neighbourhood. I would scan the bus for the faces of my friends, make sure that the bus driver was the same one that had been there in the morning, and even then ask the others over and over again to be sure I was in the right bus. On school or family trips to the amusement park or a museum,I wouldn’t let the leaders out of my sight. And of course, I was never very adventurous when it came to taking walks or hikes because I would go only where I was sure I would never get lost. Perhaps, one of the worst fears I had as a child was that of not being liked or accepted by others. First of all, I was quite shy. Secondly, I worried constantly about my looks, thinking people wouldn’t like me because I was too fat or wore braces.I tried to wear the right clothes and had intense arguments with my mother over the importance of wearing flats instead of saddled shoes to school. Being popular was very important to me then and the fear of not being liked was a powerful one. One of the processes of evolving from a child to an adult is being able to recognize and overcome our fears.I have learnt that darkness does not have to take on a life of its own, that others can help me when I am lost and that friendliness and sincerity will encourage people to like me. Understanding the things that scared us as children help us to cope with our lives as adults.Write a summary of the passage and suggest a suitable title. |

Why is an external emf of more than `2.2V` required for the extraction of `CI_(2)` from brine? |
|
Answer» The oxidation reaction involved in the oxidation of `Cl^(-) " ions to " Cl_(2)` is : `2Cl^(-)(aq)+2H_(2)O(l) to 2OH^(-)(aq)+H_(2)(g)+ Cl_(2)(g)` The value of `DeltaG^(@)` for the reaction is `+422` kJ (standard value). The `E_("Cell")^(@)` can be calculated as , `DeltaG^(@)=- nF E_("Cell")^(@) " or " E_("Cell")^(@)=- (DeltaG^(@))/(nF)` `DeltaG^(@)=422 kJ =422000 J=422000 CV, n=2, `E_("Cell")^(@)=-((422000 CV))/((2xx96500 C))=-2.19~~-2*20 V`. Since `E_("Cell")^(@)` comes out to be `-2*20` V for the electrolytic cell involving the oxidation of `Cl^(-)` ions, an external emf of more than 2.2 V is needed. |

Adversity brings out the best as well as the worst in people. Elucidate this statement with reference to the story, ‘Two Gentlemen of Verona’. |
|
Answer» Whenever confronted by an adversity, there is a psychological reaction among most of us. Either fight or flee from it. Even adults run away from crisis and seek asylum or support of others. We find hordes of people, when living becomes difficult, migrate to other places to survive. In the face of adversity, even educated people turn to evil ways. They worked hard from dawn to midnight. They did any job that came their way. They shined shoes, hawked newspapers, sold wild fruits and took the people round the city. They spent very little on their food and clothes. Every week they cycled to Poleta and paid Lucia’s medical bill systematically. In this story, the nurse of the private hospital reveals the bitter truth about the economy of Verona. Jobs are scarce. There is inflation. It is difficult to buy food with limited money. When the hospital laid the condition that the little boys Nicola and Jacopo should pay the weekly medical bill for their sister Lucia’s treatment for tuberculosis, they did not back off or give up. Their best qualities came out during adversity. Like tea leaves, they gave their best while in hot waters. |

The poem ‘Water’ demonstrates the disparity and discrimination in our society. Justify. |
|
Answer» ‘Water’ is a reflective-narrative poem in which the speaker recalls several instances taken from the life of the Dalits to highlight the disparity seen in the lifestyle of the Dalits and that of the upper caste people. Incidentally, the speaker also highlights how the Dalits are discriminated against while using ‘water’ from a pond or a tank. The speaker states that water is a witnéss to the Panchama’s plight when he goes to the pond or tank to collect water. Since he does not have the right to draw a pot of water directly from a well, he waits all day near the well until a shudra arrives there and fills his pot. The speaker mentions the humiliation of the Wada girl when she receives water poured from a distance. Some waterfalls on her body and she felt humiliated. The speaker articulates the righteous indignation shown by Munnangi Suvartamma when she raised her vessel to ward off an attack by the Kamma youths against the Dalit boy who asked them not to pollute their drinking water. These instances illustrate how the Dalits were discriminated against while using water from a public well. The speaker recalls how people in the Wada would thirst all day for a glass of water while the villagers had a lot of water to drink and bathe as and when they wanted. The speaker recalls how they would look forward to that day in a week when they would get an occasion to take a bath. On the other hand, the people in the village enjoyed a bath twice a day, because they had plenty of water, and the Dalits were made to forego water on the pretext of untouchability. The speaker narrates how, in her childhood, they walked miles and miles to collect water from the big canal and walked back carrying heavy pots of water on their heads, with the veins in their neck straining and bursting. Finally, the speaker recalls how several thatched huts in Malapalle were reduced to ashes for want of a pot of water to douse the fire. |

Wrought iron is the purest form of iron. Write a reation used for the preparation of wrought iron from cast iron. How can the impurities of sulphur, silicon and phosphorus be removed from cast iron? |
|
Answer» Wrought iron contains lesser proportion of carbon contents (0.2 to 0.5%) as compared to cast iron (2.5 to 4.5%). In order to reduce the percentage of carbon, cast iron is heated with haemtite `(Fe_(2)O_(3))` at a temperature above 1073 K in a reverberatory furnace. `Fe_(2)O_(3)(s)+3C(s) overset("heat") to underset(("Cast iron")) (2 Fe(s)) + 2 CO(g)` Lime stone `(CaCO_(3))` is added as flux in the extraction of cast iron from haematite ore. Upon decomposition, it provides CaO. In the Blast furnace, the impurities of silicon, sulphur and phosphorus are converted into their respective oxides. These combine with CaO to form corresponding salts which pass into the slag. `{:(SiO_(2)+CaO to CaSiO_(3) ("Slag")),(SO_(3)+CaO to CaSO_(4)("Slag")),(P_(4)O_(10)+6CaO to 2Ca_(3) (PO_(4))_(2)("Slag")):}` |

What role did Sheela Rani play in the cycling movement? |
|
Answer» Sheela Rani Chunkath was the district collector of Pudukkottai. In 1991 as a part of the female literacy drive, she wanted to train female literacy activists so that hierarchy would reach women in the interior. She had realized that the lack of mobility among women played a big role in undermining their confidence. Therefore, she included ‘mobility’ as a part of the literacy drive. Naturally, the literacy activists learned cycling first. This inspired the neo-literates also to learn cycling. This, in turn, inspired every woman in the village to learn cycling. The literates, having become neo-cyclists, encouraged every woman in the district to learn cycling, by organizing ‘cycle training camps’. Thus, Sheela Rani Chunkath became instrumental in ‘cycling’ becoming a social movement in Pudukkottai district. |

How does the poem ‘Heaven, if you are not here on Earth’ visualise heaven? |
|
Answer» Kuvempu considers concepts like ‘God’, ‘nymphs’ and ‘heaven’ as myths created by man. He opines that if at all ‘heaven’ exists it exists only on this earth and nowhere else. In order to break the illusion of heaven in man’s mind, he presents before us charming sights of nature and argues that nothing can be more heavenly than these forms of nature. He makes a direct address to nature and declares that if heaven does not exist on the earth where else can it be. He justifies his statement referring to the streams, the waves, and the sunlight. He says that the streams that leap down roaring from the top of the hills, the rolling surf at the edge of the waves, the tender rays of sunlight falling on the green forests, the gentle sun warming the earth all these make the earth heaven. |

Wheel brings ‘freedom and progress’ – Explain this statement with reference to ‘Where there is a wheel’. |
|
Answer» In ‘Where there is a Wheel’, R Sainath, the writer, refers to the ‘wheel’ of the bicycle to document the spectacular progress achieved by rural women in the Pudukkottai district of Tamilnadu. The title symbolically conveys the ‘progress’ achieved by rural women over a period of one and a half years. ‘Wheel’ is a commonly accepted symbol for progress or movement or mobility ‘Wheel’ also means continuous progress or movement. While stagnation indicates decay and deterioration, mobility indicates dynamism. The writer remarks that “people find curious ways of hitting out at their backwardness, of expressing defiance, a hammering at the fetters that hold them’ All these phrases make a reference to how the rural women of Pudukkottai district defied the challenge of the male bastion and broke the fetters that chained them to the confines of their homes by learning to ride a bicycle. These rural women, which included agricultural workers, quarry labourers, village health nurses, baiwadis and anganwadis, gem cutters, school teachers, mid-day meal workers and gram services, had to depend on the male persons at-home — brother, husband, father — to go to the market to sell their produce and to go to their workplaces in addition to doing household chores like carrying water from the village well, cooking, taking care of infants and washing clothes and utensils. Today, women can be seen doing many tasks on their bicycles. They can be seen carrying water from the well along with their small kids sitting on the bar of their cycle in the front. Many of them bicycle their way to villages to sell agricultural products or to work in the quarries. |

The two main characters in the story are Marcus and Roof, and the voters are the people of Umuofia. The whole focus of the plot is to ridicule greedy and selfish politicians and to show how they manage to corrupt the society also. Marcus was a not-too-successful mission school teacher. When he was almost on the verge of dismissal on the basis of a female teacher’s complaint, he joined politics, got elected as a representative of Umuofìa and was made Minister of Culture. In about five years, people see a great many changes in Marcus’ life. Their elected representative becomes wealthy, is awarded chieftaincy titles and doctorate degrees besides many other honours. He also builds a huge mansion in his native village. In a satirical tone, the writer says that Marcus had christened his new house ‘Umuofla Mansions’ in honour of his village and had slaughtered five bulls and countless goats to entertain the people on the day it was opened by the Archbishop. Marcus believed that, by entertaining people thus, people would respect him and would hold him in high esteem. But the people are not naive and ignorant. They know where his ‘power’ and money come from. The people know that he had acquired all this only after they had elected him their representative giving their votes free of charge five years ago. Even after five years, the people and their village remained the same as before but Marcus had changed completely. When Roof tells Marcus that a radical change had come into the thinking of Umuofia since the last election, like any other corrupt politician Marcus prepares himself to bribe the people. The people come prepared to demand their share in his wealth. Instead of demanding developmental work for their village, the people tell Roof that two shillings is too shameful and settle the deal for four shillings each. It is Marcus and Roof who blatantly offer money, tacitly admitting that they have used the public money selfishly for their own development, that the voter ridicules them by demanding more money for their vote, sending the message that real power to change the face of a village, town or country is in the hands of the voter and not selfish politicians like Marcus. |

Why does the poet feel that earth is more beautiful than heaven in the poem “heaven, if you are not here on earth”. |
|
Answer» The poet doesn’t want to search for heaven which is nowhere. Also, he wants to create heaven in his surroundings, so he breaks the myth of heaven by asking where is heaven if not on earth. Man is God himself by having goodness in his heart and he should not search anywhere else for God. Barth is beautiful than heaven as earth consists of green trees, rushing streams, rolling waves, and shining sun, bright and calm moonlight which makes the harvest crops to shine. |
