Q:Directions :Read the given passage carefully and answer the following questions. Certain parts have been highlighted to help answer the questions.
Every year, around one million people die of mosquitoborne diseases according to the World Health Organization (WHO). This is why mosquitoes are considered one of the deadliest living creatures on the planet — not because they are lethal themselves, but because many of the viruses and parasites they transmit are
In the absence of an effective vaccine for dengue fever, Zika fever, chikungunya and other mosquito-borne diseases, researchers have developed genetic strategies to reduce mosquito populations. One such strategy involves the release into the wild of genetically modified (GM) mosquitoes that express a lethal gene — a strategy believed to have little impact on the overall DNA of wild populations of mosquitoes
The transfer of new genes from GM organisms to wild or domesticated non-GM populations is a key criticism of GM crops like soybean and corn. There are concerns that the introduction of GM genes into non-target species could have negative consequences for both human and environmental health.
Oxitec, a company that spun out of research at Oxford University in the early 2000s, developed and trademarked GM Friendly™ mosquitoes (also known as strain OX513A of Aedes aegypti). These male GM mosquitoes have what the company describes as a “self-limiting” gene, which means that when these so-called friendly mosquitoes’ mate, their offspring inherit the self-limiting gene which is supposed to prevent them surviving into adulthood.
In theory, when these mosquitoes are released in high numbers, a dramatic reduction in the mosquito population should follow. According to research published by Oxitec researchers in 2015, field trials involving recurring releases of Friendly™ mosquitoes demonstrated a reduction of nearly 95 per cent of target populations in Brazil. In these field trials, experiments were not performed to assess whether GM mosquitoes might persist in the wild.
A recent study from the Powell lab at Yale University has since confirmed that some of the offspring of the GM mosquitoes didn’t succumb to the self-limiting lethal gene and survived to adulthood. They were able to breed with native mosquitoes and thereby introduce some of their genes into the wild population
Meanwhile, the impact of mosquitoes carrying these new genes remains largely unknown. One significant worry is that a new breed of mosquito might emerge that is more difficult to control. These new genes could also potentially alter evolutionary pressures on viruses carried by mosquitoes, like dengue fever, in unpredictable ways. This includes potentially increasing their virulence or changing their host-insect interactions. These are hypothetical risks that have been raised by scientists, and reflect the need for further study.
What is the desired effect of releasing GM mosquitoes containing the ‘Self-limiting Gene’?

Q:Directions: 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 questions.
Among those suffering from the global recession are millions of workers who are not even included in the official statistics : urban recyclers – the trash pickers, sorters, traders and reprocesses who extricate paper, cardboard and plastics from garbage heaps and prepare them for reuse. Their work is both unrecorded and largely unrecognized, even though in some parts of the World they handle as much as 20% of all waste.
The World’s 15 million informal recyclers clean up cities, prevent some trash from ending in landfills and thus, reduce climate change by saving energy on waste disposal techniques like incineration. In the developed countries they are the preferred ones since they recycle waste much more cheaply and efficiently than governments or private corporations can. In the developing World, on the other hand, they provide the only recycling services except for a few big cities. But as recession hits the markets Worldwide, the price of scrap metal, paper and plastic has also fallen. Recyclers throughout the World are experiencing a sharp drop in income. Trash pickers and scrap dealers saw a decline of as much as 80% in the price of scrap from October 2007 to October 2009. In some countries scrap dealers have shuttered so quickly that researchers at the Solid Waste Management Association didn’t have a chance to record their losses. In Delhi, some 80% of families in the informal recycling business surveyed by an organization said they had cut back on “luxury foods,” which they defined as fruit, milk and meat. About 41% had stopped buying milk for their children. By this summer, most of those children, already malnourished, hadn’t had a glass of milk in nine months. Many of these children have also cut down on hours spent in school to work alongside their parents. Families have liquidated their most valuable assets – primarily copper from electrical wires – and have stopped sending remittances back to their rural villages. Many have also sold their emergency stores of grain. Their misery is not as familiar as that of the laid-off workers of big name but imploding, service sector corporation, but it is often more tragic. Few countries have adopted emergency measures to help trash pickers. Brazil, for one, is providing recyclers, or “catadores,” with cheaper food, both through arrangements with local farmers and by offering food subsidies. Other countries, with the support of non-governmental organizations and donor agencies are following Brazil’s example. Unfortunately, most trash pickers operate outside official notice and end up falling through the cracks of programmes like these. In the long run, though, these invisible workers will remain especially vulnerable to economic slowdowns unless they are integrated into the formal business sector, where they can have insurance and reliable wages. This is not hard to accomplish. Informal junk shops should have to apply for licences, and governments should create or expand doorstep waste collection programmes to employ trash pickers. Instead of sorting through haphazard trash heaps and landfills, the pickers would have access to the cleaner scrap that comes from households.
The need of the hour, however, is a more immediate solution. An efficient but temporary solution would be for governments where they’d have to pay a small subsidy to waste dealers so they could purchase scrap from trash pickers at about 20% above the current price. This increase, if well advertised and broadky utilized, would bring recyclers a higher price and eventually bring them back from the brink. Trash pickers make our cities healthier and more liveable. We all stand to gain by making sure that the work of recycling remains sustainable for years to come.
Which of the following has not been an effect of the losses observed in the informal waste recycling?

Q:Read the passage carefully and give the answer of following questions.
Our awareness of time has reached such a pitch of intensity that we suffer acutely whenever our travels take us into some corner of the world where people are not interested in minutes and seconds. The unpunctuality of the orient, for example is appalling to those who come freshly from a land of fixed meal-times and regular train services. For a modern American or Englishman, waiting is a psychological torture. An Indian accepts the blank hours with linked together by amazingly sensitive, near-instantaneous communications. Human work will move out of the factory and mass office into the community and the home. Machines will be synchronized, as some already are, to the billionth of a second; men will be de-synchronized. The factory whistle will vanish. Even the clock, “the key machine of the modern industrial age” as Lewis Mumford called it a generation ago, will lose some of its power over humans, as distinct from purely technological affairs. Simultaneously, the organisation needed to control technology shift from bureaucracy to Ad-hocracy, from permanence to transience, and from a concern with the present to a focus on the future.
In such a world, the most valued attributes of the industrial age become handicaps. The technology of tomorrow requires not millions of lightly lettered men, ready to work in unison at endlessly repetitive jobs, it requires not men who take orders in unblinking fashion, aware that the price of bread is mechanical submission to authority, but men who can make critical judgments, who can weave their way through novel environments, who are quick to spot new relationships in the rapidly changing reality. It requires men who, in C.P. Snow’s compelling terms, “have the future in their bones”.

Q:Read the following passage carefully and give the answer of following questions.
Art both reflects and interprets the notion that produced it. Portraiture was the dominant theme of British painting up to the end of the eighteenth century because of a persistent demand for it. It would be unfair to say that human vanity and pride of possessions were the only reasons for this persistent demand, but certainly these motives played their part in shaping the course of British painting. Generally speaking, it is the artist's enthusiasm that accounts for the vitality of the picture, but it is the client who dictates its subject-matter. The history of national enthusiasms can be pretty accurately estimated by examining the subject-matter of a nation's art.
There is one type of subject which recurs again and again in British painting of the late eighteenth century and the jart half of the nineteenth and which is hardly met with in the jart of any other country ---- the sporting picture, or rather the picture in which a love of outdoor life is directed into the channel of sport. The sporting picture is really an extension of the conversation piece. In it the emphasis is even more firmly based on the descriptive side of painting. It made severe demands on the artist and it must be-confessed that painters capable of satisfying these demands were rare. The ability to paint a reasonably convincing landscape is not often combined with the necessary knowledge of horses and dogs in movement and the power to introduce a portrait when necessary. To weld such diverse elements into a satisfactory aesthetic unity requires exceptional ability. It is not surprising, therefore, that while sporting pictures abound in England, especially in the private collections of country squires, not many of them are of real importance as works of art. What makes the sporting picture worth noting in, a history of British painting is the fact that it is as truly indigenous and as truly popular a form of art in England as was the religious ikon in Russia.

Q:Read the passage carefully and give the answer of following questions.
Looking back on those days I see myself as a kind of centaur, half boy, half bike, forever wheeling down suburban streets under the poincianas, on my way to football practice or the library or to a meeting of the little group of us, girls and boys, that came together on someone's verandah in the evenings after tea.
I might come across the Professor then on his after dinner stroll; and as often as not, he would be accompanied by my father, who would stop me and demand (partly, I thought, to impress the Professor) where I was off to or where I had been; insisting, with more than his usual force, that I come home right away, with no argument I spent long hours cycling back and forth between our house and Ross McDowell or Jimmy Larwood's, my friends from school, and the Professor's house was always on the route, I was always aboard and waiting for something significant to occur, for life somehow to declare it self and catch me up I rode my bike in slow circles or figures-of-eight, took it for sprints across the gravel of the park, or simply hung motionless in the saddle, balanced and waiting.
