In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.

Article: Have you ever wondered why stems grow upwards and roots downwards? Why plants always seem to turn, towards the light and climbing plants run up rather than down? The answer is simple:auxin,a chemical substance that controls growth in plants. Auxin gives away its secrets Auxin is a plant hormone . Darwin was already interested in it in the 19th century. Only in recent years, however, has the hormone started to give away its secrets ,thanks to intensive molecular research.Auxin is produced in the young,growing parts of plants and then transported throughout the plant-to a low -lying stem for example. The stem needs to straighten out as soon as possible to be able to absorb the topside,resulting in the underside growing faster and the stem straightening out. For the same reason, plants in front of windows will always turn to the light . This active regulation of auxin transport allows plants to take ideal advantage of local and changing conditions. A new means of transport for auxin? The transport of auxin through the plant plays a vital role. And ,from all appearances,it is not a simple matter. The researchers identified an important new link and means of transport for auxin: PILS proteins . PILS proteins are vital for auxin-dependent plant growth and adjust the intracellular storage of the hormone. It is exactly this compartmentalizing of auxin that seems functionally important for the various developmental processes. Growing crops more efficiently: the right amount of auxin in the right place Higher auxin levels at the right moment and in the right place result in better growth and greater harvest. Better adjustment of auxin levels would make plants grow more efficiently. The researchers hope to contribute to the development of more efficient growing processes by continuing to sort out auxin transport processes.
Question: Which of the following is true of ausin according to the text?
Options: (A) It helps the plant to bend at the right places while growing. (B) It prevents the roots of plants from growing faster. (C) It is no use when the surroundings have changed. (D) It helps the underside of plants grow faster than the topside.
Asnwer: C
No

Article: In the dark and damp market,Chen ShuChu,near her sixties,owns a stall that her father left her.The stall,called YuanJin Vegetables,is her everything.Chen earns only a little money by selling vegetables,but she has donated about $321,550 to help poor children. In March,Forbes magazine named her one of the 48 great philanthropists from the AsiaPacific region.A month later,TIME magazine selected the year's top 100 influential people and Chen was one of them.Although she has received many honours and rewards,Chen only cares about her vegetable stall and whether her regular customers buy her vegetables or not."I do not place great importance on money.When I donate to help others,I feel happy and I can sleep well at night." Chen said. Chen's ability to donate such a great deal of money has led many to ask,"How can a vegetable seller donate so much?" "Spend only on what you need,and you'll be able to save a lot of money!" Chen said.Chen leads a very simple life.All she needs is food and a place to sleep.Everything else is a luxury .Neither does she have any desire for material gains nor any form of enjoyment.Work,she says,is her enjoyment."I love my work.If I don't how would I be able to work 16 hours a day?"Being the first to arrive and last to leave,she has been given the title of "market manager." She is content with what she has.She feels that as long as she lives the life she wishes for and does the things she wants,that is good enough.
Question: In Chen's eyes,a luxury is about _ .
Options: (A) any form of enjoyment (B) doing what she wants (C) gaining material benefits (D) everything except food and a bed
Asnwer: D
Yes

Article: The Asuncion zoo is looking for a mate for Coco, an endangered hyacinth macaw ,and it is the last known male of his species left in Paraguay. Coco was sent to the zoo eight years ago. A recent DNA test showed that he is male. Zoo worker Celia said To avoid mixing species, the zoo has had to keep him apart from the other macaws, which has left him lonely and bored. "He is quite sociable, although he has only learned to say 'Hello', but when he hears music, he dances" Celia said He has a yellow circle around his eyes that set off the rest of his blue feathers. He is more or less a cousin to Blu , he macaw that starts in the movie, Rio.That species, cyanopsitta-spixii ,is all blue and even more endangered than the hyacinth macaw. Like the bird in the movie, scientists hope to find Coco a mate to- rebuild the species. Because international laws against animal training are now so strict, nobody is willing to lend the zoo a female. "The best solution is to find a female hyacinth macaw in our country. " Celia said, "there are at least two other known hyacinth-macaws but without DNA test, it is impossible to know if they are female, and the owners are not willing to help,because the mating process can take some time and be a little hard on females."
Question: From the text we know that Coco _
Options: (A) is the last known hyacinth macaw (B) lives apart from the other macaws (C) has adapted to being left alone (D) can say "Hello" when he hears music
Asnwer: B
Yes
