Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alternating with some 16-17 hours' wakefulness and that the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified. The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently. The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night-shift workers was carried out by Brown in 1957. She found a high incidence of disturbed sleep and other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work. This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the pressure of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People occupied in normal daytime work will have a high temperature during the hours of wakefulness and a low one at night; when they change to night work the pattern will only gradually go back to match the new routine and the... Options: A Body temperature may serve as an indication of a worker's performance. B The selection of a number of permanent night shift workers has proved to be the best solution to problems of the round-the- clock working system. C Taking body temperature at regular intervals can show how a person adapts to the changes of routine. D Disturbed sleep occurs less frequently among those on permanent night or day shifts. Answer: B The selection of a number of permanent night shift workers has proved to be the best solution to problems of the round-the- clock working system. Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Our body clock,or natural body rhythm,influences our energy and alertness.Paying attention to it can help us choose the suitable time of day when we best perform specific tasks. The reality,however,is that most of us organize their time around work demands,school deadlines,commuting or social events.Doing whatever your body feels like doing is a luxury in today's fast-paced modem society. But that doesn't mean it isn't worth trying.Obeying our body clock has significant health benefits.Disrupting our natural body rhythm,on the other hand,has been linked to problems such as depression,obesity,or headache,says Steve Key,a biology professor. When the body clock can synchronize(......)the rhythms of its natural processes,it "gives us an advantage in daily life",says Key. According to him,when it comes to cognitive work,most adults perform best in the late morning.As our body temperature starts to rise just before awakening in the morning and continues to increase until midday,our memory,alertness and concentration gradually improve. However,he adds,our ability to concentrate typically starts to decrease soon thereafter.Most of us are more easily distracted between noon and 4 pm. Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm,making that a good time for a nap. Surprisingly, tiredness may increase our creative powers.For most adults,problems that require open ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning. When choosing a time of day to exercise,paying attention to your body clock can improve results.Physical performance is usually best from about 3 to 6 pm,says Michael Smolensky,a professor of biomedical engineering. Of course, not everyone's body clock is the same,making it even harder to synchronize natural rhythms with daily plans. Options: A Our alertness is influenced by our natural body rhythm B Doing whatever your body feels like is very difficult in our modem society. C Obeying our body clock is good for our health. D Disrupting our natural body rhythm can lead to obesity. Answer: D Disrupting our natural body rhythm can lead to obesity. Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: The number of speakers of English in Shakespeare's time is estimated to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms. In fact, it is impossible to estimate the number of people in the world who have acquired an adequate working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation. The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West. Options: A It was popular during Shakespeare's time. B It is used in former British colonies. C It serves the needs of its native speakers. D It is a world language that is used for international communication. Answer: D It is a world language that is used for international communication. Question:
A:
According to the passage, what is the main reason for the widespread use of English?
