MCQ-> Read the following passage carefully and answer the question given below it.Certain words/phrases have been printed in bold to help you locate them while answering some of the questions.Once upon a time a dishonest King had a man call the Valuer in his court. The Valuer set the price which ought to be paid for horses and elephants and the other animals.He also set the price on jewellery and gold.and things of that kind.This man was honest and just and set the proper price to be paid to the owners of the goods.The King however was not pleased with this Valuer because he was honest ‘If I had another sort of a man as Valuer I might gain more riches, he thought One day the King saw a stupid miserly peasant come into the place yard.The King sent for the fellow and asked him if he would like to be Valuer.The peasant said he would like the position.So the King had him made Valuer He sent the honest Valuer away from the place.Then the peasant began to set the prices on horses and elephants upon gold and jewels.He did not know their value so he would say anything he chose.As the King had made him Valuer the People had to sell their goods for the price he set. By and by a horse-dealer brought five hundred horses to the court of this King.The Valuer came and said they were worth a mere measure of rice and the horses to be put in the palace stables. The horse-dealer went then to see the honest man who had been the Valuer and told him what had happened.’What shall I do ?’ asked the horses-dealer “I think you can give a present to the Valuer which will make him “Go to him and give him a fine present then say to him You said the horses are worth a measure of rice,but now tell what a measure of rice is worth ! Can you value that standing in your place by the King ?’ If he says he can go with him to the King and I will be there too” The horses-dealer thought this was a good idea.So he took a fine present to the Valuer and said what the other man had told him to say.The stupid Valuer took the present,and said,”Yes, I can go before the King with you and tell what a measure of rice is worth.I can go before the King with you and tell what a measure of rice is worth. I can value now. Well let us go at once” said the horses-dealer.So they went before the king and his ministers in the palace.The horses-dealer bowed down before the King and said “O King I have learned that a measure of rice is the value of my five hundred horses.But will the King be pleased to ask the Valuer what had happened asked,How now Valuer what are five hundred horses worth ? “A measure of rice O King !” said he “very good then ! If five hundred horses are worth a measure of rice what is the measure of rice worth ?” The measure of rice is worth your whole city” replied the foolish fellow The minister clapped their hands laughing and saying “What a foolish Valuer! How can such a man hold that office ? We used to think this great city was beyond price but this man says it is worth only a measure of rice.Then the King was ashamed and drove out the foolish fellow “I tried to please the King by setting a low price on the horses and now see what has happened to me !’ said the Valuer as he ran away from the laughing crowd.Who did the King appoint as the new Valuer ?

MCQ-> Read the passage carefully and answer the questions given. . . “Everybody pretty much agrees that the relationship between elephants and people has dramatically changed,” [says psychologist Gay] Bradshaw. . . . “Where for centuries humans and elephants lived in relatively peaceful coexistence, there is now hostility and violence. Now, I use the term ‘violence’ because of the intentionality associated with it, both in the aggression of humans and, at times, the recently observed behavior of elephants.” . . .Typically, elephant researchers have cited, as a cause of aggression, the high levels of testosterone in newly matured male elephants or the competition for land and resources between elephants and humans. But. . . Bradshaw and several colleagues argue. . . that today’s elephant populations are suffering from a form of chronic stress, a kind of species-wide trauma. Decades of poaching and culling and habitat loss, they claim, have so disrupted the intricate web of familial and societal relations by which young elephants have traditionally been raised in the wild, and by which established elephant herds are governed, that what we are now witnessing is nothing less than a precipitous collapse of elephant culture. . . .Elephants, when left to their own devices, are profoundly social creatures. . . . Young elephants are raised within an extended, multitiered network of doting female caregivers that includes the birth mother, grandmothers, aunts and friends. These relations are maintained over a life span as long as 70 years. Studies of established herds have shown that young elephants stay within 15 feet of their mothers for nearly all of their first eight years of life, after which young females are socialized into the matriarchal network, while young males go off for a time into an all-male social group before coming back into the fold as mature adults. . . .This fabric of elephant society, Bradshaw and her colleagues [demonstrate], ha[s] effectively been frayed by years of habitat loss and poaching, along with systematic culling by government agencies to control elephant numbers and translocations of herds to different habitats. . . . As a result of such social upheaval, calves are now being born to and raised by ever younger and inexperienced mothers. Young orphaned elephants, meanwhile, that have witnessed the death of a parent at the hands of poachers are coming of age in the absence of the support system that defines traditional elephant life. “The loss of elephant elders,” [says] Bradshaw . . . "and the traumatic experience of witnessing the massacres of their family, impairs normal brain and behavior development in young elephants.”What Bradshaw and her colleagues describe would seem to be an extreme form of anthropocentric conjecture if the evidence that they’ve compiled from various elephant researchers. . . weren’t so compelling. The elephants of decimated herds, especially orphans who’ve watched the death of their parents and elders from poaching and culling, exhibit behavior typically associated with post-traumatic stress disorder and other trauma-related disorders in humans: abnormal startle response, unpredictable asocial behavior, inattentive mothering and hyperaggression. . . .[According to Bradshaw], “Elephants are suffering and behaving in the same ways that we recognize in ourselves as a result of violence. . . . Except perhaps for a few specific features, brain organization and early development of elephants and humans are extremely similar.”Which of the following statements best expresses the overall argument of this passage?
