Read carefully the passages given below and answer the questions that followAll that could be seen on the station platform at Chainpur was a cloud of confetii. Brigthly coloured paper flags danced above bamboo sticks, held by hundreds of excited childen who had come to meet the Jeevan Rekha Express. Then, in a thin monsoon drizzle, the train emerged around the corner, the brass band stuck up and children clapped, mesmerised, as the carriages, painted with rows of red, yellow and blue daisies, slid into the sliding.Minutes later, while officials exchanged greetings and garlands, a carriage door opened and the children clambered on to the train. Still clutching their flags, they peered cautionsly at the three shiny red operating tables, the dials and the anaesthetic machines which had replaced the rows of seats.The Jeevan Rekha or Lifeline Express, is reportedly the world’s first hospital train, bringing surgical care for the first time to hundreds of remote rural villages.I joined the train at Kalahari, a tiny coalmining village in a forested area of southern water and electricity supply, although it has its own water filtering machine and a generator to take over during power shortages. The two roomed station building had also to function as a calliper workshop, diagonstic centre, registration area and accommodation for relatives and patients.Operations have been confined to three areas; orthopaedic surgery for polio, cataract and middle ear operations. Callipers, spectacles and hearing aids are also fitted and eventually the project will be integrated with an immunisation and health education programme.(a) What purpose does Lifeline Express serve? What is the other name given to it?(b) How did the children welcome the train?(c) What can one find in place of passenger seats in the train? (d) What function does the station building perform?(e) Find words from the passage which mean the same as :(i) fascinated; (ii) holding something tightly. |

Read carefully the passages given below and answer the questions that followThe ‘generation gap’ is not a new phenomenon. In every generation, the old men are found shaking their heads about the good old days when young people knew better and showed due reverence to age and tradition. The generation gap is actually the difference between the high spirits and impatience of youth on one hand and the caution and prudence of old age on the other. Young people are always full of vigour, life and energy; they are adventurous, bold, even reckless and are always willing to take risks. Caution; prudence, calm reflection, careful calculation before taking any plunge, etc are not part of their mental make up. Infact young people laugh at elders who habitually think calmly and profoundly before taking a decision and calculate the perils, if any, that may arise there of. The young and the old will always disagree because their basic approach to life is different and their was thoughts are like parallel lines, seemingly always converse. While the young are always ready for fresh adventures they are often confronted by elders who warn them against the risks they can face.Neil Armstrong who was the first human to land on the moon said, “One small step for a man but one giant leap for mankind.” Such major leaps would not have been possible if the youth did not have an adventurous spirit. “No pain, no gain” is a well known saying. The old would perhaps impress “Let us not have anything more, we have enough”. But is that reason enough to prevent the young from experimenting?(i) What do the old people talk about good old days?(ii) What is the old age contrasted with? Give an example.(iii) “The thoughts of the old and the young are like parallel lines”. Explain(iv) Which characteristic of the youth lead to major discoveries?(v) Pick out words from the passage which mean the same as:- (a) acting with or showing care for future.(b) situation of immediate danger. |
|
Answer» (i) young people showed respect to elders (ii) high spirit and impatience of youth (iii) young and the old - their thinking can not be same (iv) adventurous nature (v) (a) prudence (b) peril |

Make a precis of the following passage and suggest a suitable title : Education is not an end but a means to an end and we do not educate children for the purpose of educating them: the purpose is to prepare their for life. As soon as we realise this we will understand that it is very important to choose a system of education which will really prepare children for life. In many modern countries it has for sometime been fashionable to think that by free education for all, whether rich or poor, clever or stupid. One can solve all the problems of society and build a perfect nation. But it has been proved beyond doubt that free education for all is not enough. The number of people having high degrees from colleges and universities but getting on corresponding jobs is increasing by leaps and bounds. So, a new kind of education in which degrees enable us to get jobs is needed. |
|
Answer» Title: Job oriented Education Precised : Education is a means to prepare the students to face the challenges of life. Only free education cannot solve the problems of the country. On the other hand it has increased the number of unemployed degree holders of the nation. Hence, job oriented education is the need of the time. Total words – 150 Words in precis–50 |

Read carefully the passages given below and answer the questions that followEducation is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them; our purpose is to fit them for life. As soon as we realise this fact, we will understand that it is very important to choose a system of education which will really prepare children for life. It is not enough first to choose the first system of education one finds, or to continue with one’s system of education ;without examining it to see whether it, infact, is suitable or not. In many modern countriles, it has for sometime been fashionable to think that, by free education for all, whether rich or poor, clever or stupid - one can solve all the problems of society and build a perfect nation. But we can already see that free education; for all is not enough. We find in such countries a far larger number of people, with University degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they think low work, and infact work with the hands which is thought to be dirty - and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor; we can live without education but we die if we have no food. In countries where there are no servants because everyone is ashamed of doing such work, the professors have to waste much of their time doing manual housework. Infact when we say that all fo us must be educated to fit us for life, it means that we must be educated in such a way that, firstly each of us can do whatever job is suited to his brain, aptitude and ability. Secondly, that we can realise that all jobs are necessary to society, and that it is very bad to be ashamed of one’s works, or to scorn someone else. Only such a type of education can be called valuable to society(i) What should we keep in mind when we choose a system of education?(ii) Why do people refuse to do what they think low work?(iii) What is the definition of free education for modern countries?(iv) ‘An uneducated farmer’s work is more important than a professor’s work’. Do you agree? Why/ why not?(v) ‘Education is valuable to society’. Frame a question on this statement.(vi) Choose a word from the passage which is a synonym to ‘Contempt’. |
|
Answer» (i) the one which prepares people for life. (ii) because of more degrees than jobs. (iii) all irrespective of mutual levels/ can solve all problems. (iv) can live without education/die without food. (v) Which type of education can be called valuable to society (vi) scorn |

Read carefully the passages given below and answer the questions that followValentine’s Day is celebrated on February 14 every year to honour St.Valentine. The association of St.Valaentine’s Day with love and courtship rose from coincidence of the date with the Roman festival of Lupercalia. The festival is believed to have been in honour of Faunus, the Roman God of flocks and fertility. Also known as Lupercus, he was worshipped in a temple on Palatine Hill, and the festival was celebrated on February 14. The festival survived until the 5th century A.D.The Christian church ended the feast of Lupercalia, transforming it into the feast of St. Valentine. The name St. Valentine is given to two legendary Christian martyrs whose feasts were formerly observed on February 14. One was a Roman priest martyred in 269 A.D. The second was a Bishop of Terni martyred in Rome. In 1969, the feast day was dropped from the Vatican calendar.The great popularity of greeting cards, however, began in 19th Century England and America with cheap, efficient,colour printing methods and low postage rates. By the 1880s there were hundreds of varieties of mass-printed Christmas, New Year’s and Valentine cards. But it was Esther Howland, a 19-year-old American girl, who turned it into a global event.Born in Worcester, Massachusetts in 1828, she was the youngest of three children. She recognised the potential in mass-producing Valentine’s Day cards, when she received a fancy card from her father’s friend. She felt she could make a better one. She designed her first card and showed it to her father, who was impressed. He encouraged her to make more cards.She sent several cards to her brother, when he went on a sales trip to New York. Much to her surprise, he returned with more than $5000 in orders. Faced with the huge order, she asked her three best friends to help her. A Valentine assembly line was born at the Howland home.

Read carefully the passages given below and answer the questions that followJockeying generally involves three areas and as such Jockeys are called a Video Jockey (VJ), Radio Jockey (RJ) and Disc Jockey (DJ). With radio finding its voice again, if you are over 18, with a strong command of language, pleasant voice and love for music, being a Radio Jockey (RJ) is a new career option open to you.A friendly and interesting voice is a necessary attribute, but not an all sufficient one. The RJ must be able to research his own script and break it into interesting modules. Humour is the lifeline of radio chatting; the RJ cannot afford to compromise on that. In most cases a radio jockey has a talking time of just six minutes in a programme spread over an hour. The challenge, therefore, is to find something witty to say and then say it clearly and directly in a manner that will leave a mark. For the entire duration of your slot you have to juggle between talking to the audience playing the songs, cuing in the advertisements at predefined intervals, and entertaining requests (if it is a dial in show).This profession also demands that you continuously innovate with your scripts and make your delivery as creative as possible. Voice modulation and correct inflection of emotions are very important. An RJ must get the feel of the medium and link his conversation to the music. He must have the general knowledge of the music he plays and not just having a leaning to one genre. Pop, hip hop, the blues, rock or classical - he should know and enjoy them all. The job not only involves glamour and fun but also requires a lot of hard work. The aspiring RJs must listen to radio regularly to understand what it takes to make a good show.(i) What basic qualities should a person possess to be a radio jockey?(ii) Why has humour been called the lifeline of radio chatting?(iii) Why is radio jockeying a challenging task?(iv) How can an RJ make his script creative and innovative?(v) Which word from the passage means the same as :- “introduce new methods or ideas” |
|
Answer» (i) command over language, pleasant voice and love for music. (ii) to make his programme interesting (iii) he has to do different things at a time - talking, playing music, entertain requests. (iv) by having a good knowledge of different genres of music. (v) innovate |

Write some applications to daily life of specific heat capacity of water. |
|
Answer» (1) The oceans behave like heat "store houses" for the Earth. Due to high specific heat it absorbs a large amount of heat without appreciable rise in temperature. They moderate the temperature near the equator. Oceanstransport is the heat away from the equator areas and helps to moderate the climates there also. (2) Watermelon brought out from the refrigerator retains its coolness, because of water content in the watermelon.

A cubical region of side a has its centre at the origin. It encloses three fixed point charges, `-q` at `(0,-a//4,0)`, `+3q` at `(0, 0, 0)` and `-q` at `(0, +a//4, 0)`. Choose the correct options(s) A. The net electric flux crossing the plane `x = +a//2` is equal to the net electric flux crossing the plane ` x = -a//2` .B. The net electric flux crossing the plane `y = +a//2` is more than the net electric flux crossing the plane ` y = -a//2`.C. The net electric flux crossing the entire origin is `q//epsilon_0`.D. The net electric flux crossing the plane `z = +a//2` is equal to the net electric flux crossing the plane `x = +a//2` . |
|
Answer» Position of all the charges are symmetric about the planes `x = + a//2` and `x = - a//2`. So net electric flux then will be same. Similarly, flux through `y = + a//2`is equal to flux through `y = - a//2`/ `phi = (q_("in))/(epsilon_(0)) = (3q - q - q)/(epsilon_(0)) = (q)/(espilon_(0))` By symmetry flux through `z = + q//2` is equal to flux through `x = + q//2` |
