Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

Q: Article: Humans aren't the only ones getting a buzz from coffee.Caffeine can improve memory among honeybees and lead to better pollination .According to a recent study published in the journal Science. The study was conducted by a team of researchers at Newcastle University in the United Kingdom.They found that the nectar of some flowers,such as those from grapefruit and lemon plants,as well as certain coffee flowers,contains low doses of caffeine.To get bees to feed on these flowers,the team trained the insects to associate food with the smell of the flowers.They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine.After 24 hours,the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants. Professor Geraldine Wright led the researchers."Remembering floral traits is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are,"Wright said in a statement. Improved memory led to the better pollination.That's because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate.This also suggests that caffeine plays a role in improving the bees'ability to search for food. Researchers found that caffeine's effect on the bee brain is similar to its effect on mammals."The change is similar to that produced by caffeine in neurons associated with learning and memory in the rat brain,"Wright said. Bee populations have declining since 2007.The dramatic drop in the insects'numbers has serious effects for ecosystems and the farming industry.Bees are needed in the reproduction of crops and spreading wild flower species.Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers.
Question: Which of the following is mentioned in the passage?
Options: (A) Caffeine has no effect on the rat brain. (B) Bee population has been increasing. (C) The nectar of lemon plants contains caffeine. (D) Bees dislike nectar from sweetened flowers.

A: C

Q: Article: Certainly no creature in the sea is stranger than the common sea cucumber . All living creatures, especially human beings, have their features, but everything about the little sea cucumber seems unusual. What else can be said about an unusual animal that eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered eatable? For some fifty million years, in spite of all its strange features, the sea cucumber has lived on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of color1s, ranging from black to reddish-brown to sand-color1 and nearly white. One form even has brilliant purple tentacles . Usually the creature are cucumber-shaped--where their name comes from--and because they live in rocks, this shape, combined with flexibility, enables them to press into crevices where they are safe from animal eater and ocean currents. Although they have greedy desire for food, eating day and night, sea cucumbers have the ability to become still and live at a low metabolic rate--feeding a little or not at all for long periods, so that the living things in the ocean that provide their food have a chance to increase by a large amount. If it were not for this natural ability, they would swallow all the food available in a short time and would probably starve themselves out of existence. But the most impressive thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs. When attacked, it forces all its internal organs in its body out into water. It also removes attached structures such as tentacles. The sea cucumber will get rid of its organs and grow itself again if it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted.
Question: According to the passage, why is the shape of sea cucumbers important?
Options: (A) It helps them to protect themselves from danger. (B) It makes it easier for them to move through the mud. (C) It makes them attractive to fish. (D) It helps them to digest their food.

A: A

Q: Article: Who taught you to speak English? Your parents, while you were a child? Your teacher at school? Perhaps even the BBC as a grown-up. Whoever it was, somehow you have developed an understanding of what is rapidly becoming a truly global language. There are now about 376 million people who speak English as their first language, and about the same number who have learnt it in addition to their mother tongue. There are said to be one billion people learning English now and about 80% of the information on the Internet is in English. Is this a good thing, or a bad thing? Should we celebrate the fact that more and more of us can communicate, using a common language, across countries and cultures? Or should we worry about the dangers of " mono-culturalism", a world in which we all speak the same language, eat the same food and listen to the same music? Does it matter if an increasing number of people speak the same language? I would have thought the other way around although I have never accepted the argument that if only we all understood each other better, there would be fewer wars. _ ... If we all speak English, will we then all start eating McDonalds burgers? Surely not. If English becomes more dominant , it will kill other languages? I doubt it. When I travel in Africa or Asia, I am always surprised by how many people can speak not only their own language but often one or more other related languages, as well as English and perhaps some French or German as well. When we discussed this on Talking Point a couple of years ago, we received a wonderfully poetic email from a listener in Ireland. "The English language is a beautiful language. Maybe it's like a rose," he said. "But who would ever want their garden just full of roses?" Well, I love roses, and I think they make a beautiful addition to any garden. But the way I see it, just by planting a few roses, you don't necessarily need to pull out everything else. If more and more people want to plant English roses, that's fine by me.
Question: The author would probably agree that _ .
Options: (A) it's very hard to plant many kinds of flowers in a garden (B) it's good for people from other countries to learn English (C) more and more people like to plant roses in their gardens (D) English is easier to learn than other languages

A:
B
