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: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Problem: Article: Located in the forests near the village of Harads in northern Sweden, the Treehotel opened its doors in the summer of 2010 and offers six guest rooms.Owners, Britta and Kent Lindvall, invited designers and architects to create a series of unique tree houses that reflect the growing popularity of ecologically-themed holidays.     There's the Mirrorcube, a 4x4x4 meter aluminum box in mirrored glass.Accessed via a footbridge, the Cabin is suspended   from the surrounding pines on a steep bank, affording views of the Lulea River.Both these rooms sleep two people while the Nest (covered in branches), the Blue Cone (which is actually painted red) and the UFO (a spaceship skewered by pines) all have enough room to sleep a family of four.     The Treehotel was built after they saw a 2008 Swedish documentary   called "Tradalskaren" (The Tree Lover) that tells the story of three men who build a tree house near Harads in an attempt to rediscover their rural roots after years of living in a city.     The Lindvalls, who already owned and ran a nearby guesthouse, saw the chance to create a different kind of holiday experience."When the film was over, interest in the original tree house grew so we decided to build our own, closer to our place," Kent Lindvall said."The plan for next year is five new rooms.We also plan to build a chapel so people can get married up there."     Open all year round, the Treehotel might attract only  _ during the winter as temperatures typically dip to around minus 15 degrees Celsius.But brave travelers will be rewarded with stunning snowy landscapes as well as a "Three Sauna" and under-floor heating in every room delivered by renewable energy. 
 Question: Britta and Kent Lindvall opened the Treehotel to   _  .
