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

Read the following passage and answer the questions given after it.

We sit in the last row, bumped about but free of stares. The bus rolls out of the dull crossroads of the city, and we are soon in the open countryside, with fields of sunflowers as far as the eye can see, their heads all facing us. Where there is no water, the land reverts to the desert. While still on level ground, we see in the distance the tall range of the Mount Bogda, abrupt like a shining prism laid horizontally on the desert surface. It is over 5,000 metres high, and the peaks are under permanent snow, in powerful contrast to the flat desert all around. Heaven lake lies part of the way up this range, about 2,000 metres above sea level, at the foot of one of the highest snow-peaks. As the bus climbs, the sky, brilliant before, grows overcast. I have brought nothing warm to wear. It is all down at the hotel in Urumqi. Rain begins to fall. The man behind me is eating overpoweringly smelly goat’s cheese. The bus window leaks inhospitably but reveals a beautiful view. We have passed quickly from the desert through arable land to pasture and the ground is now green with grass, the slopes dark with pine. A few cattle drink at a clear stream flowing past moss-covered stones; it is a Constable landscape. The stream changes into a white torrent, and as we climb higher I wish more and more that I had brought with me something warmer than the pair of shorts that have served me so well in the desert. The stream (which, we are told, rises in Heaven Lake) disappears, and we continue our slow ascent. About noon, we arrive at Heaven Lake, and look for a place to stay at the foot, which is the resort area. We get a room in a small cottage, and I am happy to note that there are thick quilts on the bed. Standing outside the cottage, we survey our surroundings. Heaven Lake is long, sardine- shaped and fed by snowmelt from a stream at its head. The lake is an intense blue, surrounded on all sides by green mountain walls, dotted with distant sheep. At the head of thelake, beyond the delta of the inflowing stream, is a massive snow-capped peak which dominates the vista; it is part of a series of peaks that culminate, a little out of view, in MountBogda itself. For those who live in the resort, there is a small mess-hall by the shore. We eat here sometimes, and sometimes buy food from the vendors outside, who sell kabab and naan until the last buses leave. The kababs, cooked on skewers over charcoal braziers, are particularly good; highly spiced and well-done. Horse’s milk is available too from the local Kazakh herdsmen, but I decline this. I am so affected by the cold that Mr. Cao, the relaxed young manwho runs the mess, lends me a spare pair of trousers, several sizes too large but more than comfortable. Once I am warm again, I feel a pre-dinner spurt of energy—dinner will be long in coming—and I ask him whether the lake is good for swimming in.

Read the given passage and answer the questions that follow.
There are five basic features of services. These features distinguish them from goods. The first is that services are intangible. They are experiential in nature. One cannot taste a doctor’s treatment, or touch entertainment. One can only experience it. An important implication of this is that quality of the offer can often not be determined before consumption or before purchase. It is, therefore, important for the service providers that they consciously work on creating a desired service so that the customer undergoes a favourable experience. The second important characteristic of services is inconsistency. Since there is no standard tangible product, services have to be performed exclusively each time. Different customers have different demands and expectations. Service providers need to have an opportunity to alter their offer to closely meet the requirements of the customers. Another important characteristic of services is the simultaneous activity of production and consumption being performed. This makes the production and consumption of services inseparable. While we can manufacture a car today and sell it after, say, a month; this is often not possible with services that have to be consumed as and when they are produced. For example, the services of a teacher, doctor or lawyer. Service providers may design a substitute for the person by using appropriate technology but the interaction with the customer remains a key feature of services. Automated Teller Machines (ATMs) may replace the banking clerk for the front office activities like cash withdrawal and cheque deposit. But, at the same time, the presence of the customer, is required and his/her interaction with the process has to be managed. Services have little or no tangible components and, therefore, cannot be stored for a future use. That is, services are perishable and providers can, at best, store some associated goods but not the service itself. This means that the demand and supply needs to be managed as the service has to be performed as and when the customer asks for it. They cannot be performed earlier to be consumed at a later date. For example, a railway ticket can be stored but the railway journey will be experienced by a traveller only when the railways provide it.

What is the key feature of any service?

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.
