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.

Q: 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

A: No

Q: Article: Elena Kagan has reached a lifelong goal:becoming a Justice on the United States Supreme Court.The U.S. Senate confirmed Kagan on Thursday by a vote of 6337.She replaces Justice John Paul Stevens,who retired in June. Kagan will take a sacred oath  to uphold the Constitution of the United States on Saturday at a swearingin ceremony.The new Justice will bring the number of women sitting on the nation's highest court to three.Kagan joins Justices Ruth Bader Ginsburg and Sonia Sotomayor--all three New Yorkers. Kagan is the fourth woman in history to sit on the Supreme Court.Justice Sandra Day O'Connor was the first female Justice.She was appointed by President Ronald Reagan and served from 1981 to 2006. Kagan,who is 50 years old,is the second Justice appointed by President Barack Obama.(He appointed Justice Sotomayor in 2009.) Obama told reporters on Thursday that Kagan will make an "outstanding Justice who understands that her rulings affect people." He also noted that the addition of another woman to the Supreme Court marks a sign of progress for the country.Obama and Kagan will celebrate her confirmation with a ceremony at the White House today. Kagan has spent most of her adult life working with the law.She served in President Clinton's administration as a legal adviser,was the head of Harvard Law School,and until her confirmation Thursday,was the U.S. Solicitor General--one of the most powerful lawyers in the federal government.Kagan was born in New York City.She grew up in an apartment on the Upper West side of Manhattan,the strongwilled,independent middle sister sandwiched between two brothers. Kagan's mother was a public school teacher who taught fifth and sixth grades.Her father was a lawyer. The new Justice once wore a judge's robe in a picture for her highschool yearbook.Now she'll be wearing real ones as she and the other eight Justices decide some of the most important legal cases. 
 Question: Which of the following is TRUE according to the text? 
 Options: (A) To take the place of an old Justice,a Justice was elected by the Senate. (B) There will be four women working in the United States Supreme Court. (C) Kagan will take a sacred oath before taking part in the election. (D) No one but a New Yorker can be a Justice of the Supreme Court. 
 Asnwer: A
