MCQ-> Read the following passage carefully and answer the questions given below it. Certain words are given in bold to help you to locate them while answering some of the questions.Recent advances in science and technology have made it possible for geneticists to find out abnormalities in the unborn foetus and take remedial action to rectify some defects which would otherwise prove to be fatal to the child. Though genetic engineering is still at its infancy, scientists can now predict with greater accuracy a genetic disorder. It is not yet an exact science since they are not in a position to predict when exactly a genetic disorder will set in. While they have not yet been able to change the genetic order of the gene in germs, they are optimistic and are holding out that in the near future they might be successful in achieving this feat. They have, however , acquired the ability in manipulating tissue cells. However, genetic misinformation can sometimes be damaging for it may adversely affect people psychologically. Genetic information may lead to a tendency to brand some people as inferiors. Genetic information can therefore be abused and its application in deciding the sex of the foetus and its subsequent abortion is now hotly debated on ethical lines. But on this issue geneticists cannot be squarely blamed though this charge has often been levelled at them. It is mainly a societal problem. At persent genetic engineering is a costly process of detecting disorders but scientists hope to reduce the costs when technology becomes more advanced. This is why much progress in this area has been possible in scientifically advanced and rich countries like the U.S.A., U.K. and Japan. It remains to be seen if in the future this science will lead to the development of a race of supermen or will be able to obliterate disease from this world.Which of the following is the same in meaning as the phrase ‘holding out’ as used in the passage?

MCQ-> Read the following passage carefully and answer the questions given below it . Certain words have been printed in bold to help you locate them while answering some of the question.There was a girl who sang beautifully at the temple every morning. The music master used to happily recall, “One day when I went into the woods to pluck flowers, I found this baby under a pipal tree”. He picked her up carefully, raised her lovingly as if she were his daughter and taught her to sing before she spoke her first word. The music master grew old and didn’t see too well. The girl tended to him caringly. Many people including young men travelled from far and wide to hear her sing . This made the music master’s heart quake with fear. “You will choose one of them as your husband. What is to become of me ?” The girl replied ,”I shall not be apart from you “. But on a full moon night during the harvest festival, the master’s chief disciple touched his feet reverently and said, “Master, grant me your permission for your daughter has agreed to many me.” The master’s tears flowed freely,” She has chosen well. Go and fetch her let me hear you sing the first of many melodies that you will sing together.” The two began to sing in harmony. But the song was interrupted by the arrival of the royal messenger. “Your daughter is very fortunate– the king has sent for her,” the messenger said. At the palace the queen summoned the girl to her and said, “I place upon you the honour of making sure my daughter is never unhappy at her husband’s home.” There wasn’t a single tear in the girl’s eyes but she thought of the master and her heart was heavy.That very night the princess began her journey to Kambhoj. The princess’s royal chariotled the procession and the girl’s palanquin followed close behind carrying trunks of silk, jewellery and precious stones. It was covered with a velvet sheet and had soldiers on the both sides. As the procession passed, the master and his disciple Kumarsen stood still by wayside. A collective sigh escaped the crowd gathered there wishing that the princess wouldn’t feel homesick in her faraway home.Which of the following can be said about the girl? (A) She was brought up by her father as her mother had died when she was a baby. (B) She was a talented singer who had learnt to sing at an early age. (C) She was only allowed to sing with the master’s permission.....

MCQ-> A passage is given with 5 questions following it. Read the passage carefully and choose the best answer to each question out of the four alternatives.Genetic variation is the cornerstone of evolution, without which there can be no natural selection, and so a low genetic diversity decreases the ability of a species to survive and reproduce, explains lead author Yoshan Moodley, Professor at the Department of Zoology, University of Venda in South Africa.Two centuries ago, the black rhinoceros - which roamed much of sub Saharan Africa - had 64 different genetic lineages; but today only 20 of these lineages remain, says the paper. The species is now restricted to five countries, South Africa, Namibia, Kenya, Zimbabwe and Tanzania. Genetically unique populations that once existed in Nigeria, Cameroon, Chad, Eritrea, Ethiopia, Somalia, Mozambique, Malawi and Angola have disappeared. The origins of the 'genetic erosion' coincided with colonial rule in Africa and the popularity of big game hunting. From the second half of the 20th century, however, poaching for horns has dramatically depleted their population and genetic diversity, especially in Kenya and Tanzania.What is important for evolution?

MCQ-> Read the passage carefully and answer the questions givenGrove snails as a whole are distributed all over Europe, but a specific variety of the snail, with a distinctive white-lipped shell, is found exclusively in Ireland and in the Pyrenees mountains that lie on the border between France and Spain. The researchers sampled a total of 423 snail specimens from 36 sites distributed across Europe, with an emphasis on gathering large numbers of the white-lipped variety. When they sequenced genes from the mitochondrial DNA of each of these snails and used algorithms to analyze the genetic diversity between them, they found that. . . a distinct lineage (the snails with the white-lipped shells) was indeed endemic to the two very specific and distant places in question.Explaining this is tricky. Previously, some had speculated that the strange distributions of creatures such as the white-lipped grove snails could be explained by convergent evolution—in which two populations evolve the same trait by coincidence—but the underlying genetic similarities between the two groups rules that out. Alternately, some scientists had suggested that the white-lipped variety had simply spread over the whole continent, then been wiped out everywhere besides Ireland and the Pyrenees, but the researchers say their sampling and subsequent DNA analysis eliminate that possibility too. “If the snails naturally colonized Ireland, you would expect to find some of the same genetic type in other areas of Europe, especially Britain. We just don’t find them,” Davidson, the lead author, said in a press statement.Moreover, if they’d gradually spread across the continent, there would be some genetic variation within the white-lipped type, because evolution would introduce variety over the thousands of years it would have taken them to spread from the Pyrenees to Ireland. That variation doesn’t exist, at least in the genes sampled. This means that rather than the organism gradually expanding its range, large populations instead were somehow moved en mass to the other location within the space of a few dozen generations, ensuring a lack of genetic variety.“There is a very clear pattern, which is difficult to explain except by involving humans,” Davidson said. Humans, after all, colonized Ireland roughly 9,000 years ago, and the oldest fossil evidence of grove snails in Ireland dates to roughly the same era. Additionally, there is archaeological evidence of early sea trade between the ancient peoples of Spain and Ireland via the Atlantic and even evidence that humans routinely ate these types of snails before the advent of agriculture, as their burnt shells have been found in Stone Age trash heaps.The simplest explanation, then? Boats. These snails may have inadvertently traveled on the floor of the small, coast-hugging skiffs these early humans used for travel, or they may have been intentionally carried to Ireland by the seafarers as a food source. “The highways of the past were rivers and the ocean-as the river that flanks the Pyrenees was an ancient trade route to the Atlantic, what we’re actually seeing might be the long lasting legacy of snails that hitched a ride…as humans travelled from the South of France to Ireland 8,000 years ago,” Davidson said.The passage outlines several hypotheses and evidence related to white-lipped grove snails to arrive at the most convincing explanation for:

One day, a young man named Manikya came to Amrutananda. ask ing for work. Amrutananda was picas. antly surprised. No one ever wanted to work for him because of his reputation and here was someone wallking right into his house! Manikya’s next few words made him even happier. Manikya said, ‘1 will work for you for free. You need not pay me a salary, only give me a place to sleep, two sets of clothes and two meals a day.’ Amrutananda was filled with joy when he heard this and was about to agree. when Manikva added, ‘I have only one condition: I will tell you the truth always, but one day of the year I will lie to you.’ Amrutananda, who lied happily every day of the year. agreed to this odd condition. So Manikya joined him. He was a wonderful worker – hard – working and trustworthy. He was very honest and soon became Arnruta-nan da’s right hand man. A year went by. and because of Manikya’s hard work. Amrutananda had an excellent harvest. He and his wife Mandakini, decided to have a big feast to celebrate. They invited all their relatives and friends, who came from across the village and outside to participate in this celebration. Everyone was looking forward to the delicious feast being planned. On the morning of the feast, Amrutananda decided he would also give away some gifts to his relatives, just so that he could show-off. So he set off for the market in his cart. As soon as he was out of sight. Manikya went running to his mistress. Mandakini. He wept loudly and heat his chest. Then he tell on the floor sobbing, and announced, The master is dead.’ The cart overturned on the road. Our master has been flattened like a Chapatti” As soon as Amrutananda’s wife and relatives heard this, they started wailing.

My kind, loving mistress is dead. A cobra bit her and she fell to the ground, as blue as the spring sky.- Amrutananda was stunned. His be loved Mandakini. his partner in all his schemes, was dead! He couldn’t believe it. He rushed back home shouting her name. Mandakini was weeping loudly, Sitting in the courtyard. When she saw her husband run in, she stopped mid — wail. and Amrutananda too, stood openmouthed and speechless. Then they fell into each other’s arms, unable to believe their eyes. At once they turned to Manikya, “What is the meaning of this. Manikya his master demanded in a stern voice. Manikya smiled. “Remember my condition, that I would Ile only once in a year? Well, I choose today. You *see what lies can do? They nearly destroyed your life. Now think about what happens to the people you lie to everyday.
