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 can be the potential side effect(s) of genetically modified mosquito offspring?

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.
The interview may be conducted by letter and by telephone, as well as in person. Letter and telephone interviews are less satisfactory. Direct contact with an individual and a face-to-face relationship often provide a stimulating situation for both interviewer and interviewee. Personal reaction and interaction aid not only in rapport but also in obtaining nuances and additional information by the reactions which are more fully observed in a face-to-face relationship.
Adequate preparation for the interview is a “must”. Careful planning saves not only time but also energy of both parties concerned. The interview is used to obtain facts or subjective data such as individual opinions, attitudes, and preferences. Interviews are used to check on questionnaires which may have been used to obtain data, or when a problem being investigated is complex, or when the information needed to solve it cannot be secured easily in any other way. People will often give information orally but will not put it in writing.
Face-to-face interaction with the interviewees enables the interviewer to
