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: This will make you think twice about dismissing the physical abilities of women. Serena Williams If know Serena Williams, then you know better than to harbor any illusions that you can take on the top female tennis player even on your best day. Nicknamed by the media as the Queen of the Court, she has won 19 Grand Slam singles titles and 13 Grand Slam doubles titles as of May 2015. By the way, she can send the ball hurtling towards your face on the excess of 120 miles per hour on her serve. Ronda "Rowdy" Rousey Former Olympic judo gold medalist Ronda 'Rowdy' Rousey has been dominating women's MMA for the past several years. She earned the nickname "The Arm Collector" for winning the majority of her fights via armbars. As of May 2015, no other female MMA has put up much of a challenge against Rousey, but some think that the next entry on this list just might give her trouble. Cristiane 'Cyborg' Justmo Many believe that Cris Cyborg will give Rousey trouble and may even have an outside chance of beating her. While Rousey is an excellent grappler owing to her judo background, Cyborg is a more well-rounded fighter with excellent standup and groundwork skills. This means that just like Rousey, Cyborg can lay some serious beatdown on you. Missy Franklin So you think you are a good swimmer. Well, no matter how good you think you are, you'll very likely still be eating Missy Franklin's pool dust. Missy is a four-time Olympic gold medalist and has also won a bunch of gold medals in the World Championships. Mirinda Carfae Do you think you can swim 2.4 miles, ride a bike for 115 miles, and still have enough gas to run for 26 miles? Mirinda Carfae certainly can and she proved that she can do it faster than any woman winning the Ironman World Championships women's division in 2010, 2013, an 2014.

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 Input: Article: On a hot August morning, in a classroom overlooking New York's Hudson River, a teacher guides a group of 3-year-olds completely in Chinese. This is just a language summer camp run by the primary school Bilingual Buds, which offers a year-round course in Chinese as well as Spanish for kids as young as 2. A lot of research now shows the regular, high-level use of more than one language may actually improve early brain development. Knowing two or more languages can improve the ability to focus, decide and deal with information better. These important skills are grouped together, known in brain terms as "executive function". The research suggests _ develop ahead of time in bilingual children, and are already evident in kids as young as 3 or 4. Bilingual education, common in many countries, is a growing trend across the United States, with 440 elementary schools offering the study in Spanish, Chinese and French. But Tamar Gollan, a professor at the University of California, has found a vocabulary gap between children who speak only one language and those who grow up with more. On average, the more language spoken, the smaller the vocabulary in each one. Gollan's research suggests that while that gap narrows as children grow, it does not disappear completely. Gollan says, "Vocabulary tests help us find that bilinguals have the disadvantage, where you know the word but you just can't get it out." In fact some of the values of bilingualism can't be measured at all, of course. To speak more than one language is to open the mind to more than one culture or way of life. Bilinguals also appear to be better at learning other new languages. Clarisse spent her early childhood in Switzerland speaking French. At 6, she learned English. Later she learned Spanish, German, and, during three years living in Tokyo, Japanese. Now she has easily mastered several languages.
Question: According to Tamar Gollan, _ .
Options: (A) knowing two or more languages can improve children's skills (B) the more languages children know, the better they will be (C) children had better not take vocabulary tests (D) bilingual education is not always good to children
Asnwer: B
Example Output:
No
