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.

Example Input: Article: For years, there has been a bias against science among clinical psychologists . In a two-year analysis to be published in November inPerspectives on Psychological Science, psychologists led by Timothy B. Baker of the University of Wisconsin charge that many clinical psychologists fail to "provide the treatments for which there is the strongest evidence of effectiveness" and "give more weight to their personal experiences than to science." As a result, patients have no guarantee that their "treatment will be informed by ... science." Walter Mischel of Columbia University is even crueler in his judgment. "The disconnect between what clinical psychologists do and what science has discovered is an extreme embarrassment," he told me, and "there is a widening gap between clinical practice and science." The "widening" reflects the great progress that psychological research has made in identifying the most effective treatments. Thanks to strict clinical trials, we now know that teaching patients to think about their thoughts in new, healthier ways and to act on those new ways of thinking are effective against depression, panic disorder and other problems, with multiple trials showing that these treatments -- the tools of psychology -- bring more lasting benefits than drugs. You wouldn't know this if you sought help from a typical clinical psychologist. Although many treatments are effective, relatively few psychologists learn or practice them. Why in the world not? For one thing, says Baker, clinical psychologists are "very doubtful about the role of science" and "lack solid science training". Also, one third of patients get better no matter what treatment (if any) they have, "and psychologists remember these successes, believing, wrongly, that they are the result of the treatment." When faced with evidence that treatments they offer are not supported by science, clinical psychologists argue that they know better than some study what works. A 2008 study of 591 psychologists in private practice found that they rely more on their own and colleagues' experience than on science when deciding how to treat a patient. If they keep on this path as insurance companies demand evidence-based medicine, warns Mischel, psychology will "discredit itself."

Example Input: Article: LONDON ( Reuters)-- Ecotourism is causing a lot of damage to wildlife and may be endangering the survival of the very animals people are flocking to see, according to researchers. Biologists and conservationists are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying. "Evidence is growing that many animals do not react well to tourists in their backyard," New Scientist magazine said. The immediate effects researchers have noticed are changes in behavior, heart rates, or stress hormone levels but they fear it could get much worse and over the long term "could endanger the survival of the very wildlife they want to see". Although money produced through ecotourism, which has been growing at about 10--30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union (IUCN) and some governments fear not all projects are audited and based on environmentally friendly policies, according to the magazine. "The transmission of disease to wildlife, or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding," said Philip Seddon, of the University of Otago in Dunedin, New Zealand. Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by ecotourists are producing smaller babies. Conservationists are now calling for more research into the effect of ecotourism on animals and say the industry must be developed carefully. They also want studies done before new ecotourism projects are started. "The animals' welfare should be very important because without them there will be no ecotourism," said Rochelle Constantine of the University of Auckland in New Zealand.
Question: What's the text mainly about?
Options: (A) Many animals are dying because of lack of money. (B) There will be no ecotourism without animals. (C) Ecotourism could endanger the survival of the wildlife people want to see. (D) More research should be done on ecotourism.
Asnwer: D
Example Output: No

Example Input: Article: My heart sank when the man at the immigration counter gestured to the back room. I was born and raised in America, and this was Miami, where I live, but they weren't quite ready to let me in yet. "Please wait in here, Ms. Abujaber," the immigration officer said. My husband, with his very American last name, accompanied me. He was getting used to this. The same thing had happened recently in Canada when I'd flown to Montreal to speak at a book event. That time they held me for 45 minutes. Today we were returning from a literary festival in Jamaica, and I was shocked that I was being sent "in back" once again. The officer behind the counter called me up and said, "Miss, your name looks like the name of someone who's on our wanted list. We're going to have to check you out with Washington." "How long will it take?" "Hard to say...a few minutes," he said, "We'll call you when we're ready for you." After an hour, Washington still hadn't decided anything about me. "Isn't this computerized?" I asked at the counter, "Can't you just look me up?" "Just a few more minutes," they assured me. After an hour and a half, I pulled my cell phone out to call the friends I was supposed to meet that evening. An officer rushed over. "No phones!" he said, "For all we know you could be calling a terrorist cell and giving them information." "I'm just a university professor," I said. My voice came out in a squeak. "Of course you are. And we take people like you out of here in leg irons every day." I put my phone away. My husband and I were getting hungry and tired. Whole families had been brought into the waiting room, and the place was packed with excitable children, exhausted parents, and even a flight attendant. I wanted to scream, to jump on a chair and shout: "I'm an American citizen; a novelist; I probably teach English literature to your children." After two hours in detention , I was approached by one of the officers. "You're free to go," he said. No explanation or apologies. For a moment, neither of us moved. We were still in shock. Then we leaped to our feet. "Oh, one more thing," he handed me a tattered photocopy with an address on it, "If you aren't happy with your treatment, you can write to this agency." "Will they respond?" I asked. "I don't know--I don't know of anyone who's ever written to them before." Then he added," By the way, this will probably keep happening each time you travel internationally." "What can I do to keep it from happening again?" He smiled the empty smile we'd seen all day, "Absolutely nothing." After telling several friends about our ordeal, probably the most frequent advice I've heard in response is to change my name. Twenty years ago, my own graduate school writing professor advised me to write under a pen name so that publishers wouldn't stick me in what he called "the ethnic ghetto"--a separate, secondary shelf in the bookstore. But a name is an integral part of anyone's personal and professional identity--just like the town you're born in and the place where you're raised. Like my father, I'll keep the name, but my airport experience has given me a whole new perspective on what diversity and tolerance are supposed to mean. I had no idea that being an American would ever be this hard.
