Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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.
Question: Researchers did experiments on kids in order to find out _ .
Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness
Answer: B
Solution: Yes
Reason: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. Hence, B is the correct answer and output is Yes.

Now, solve this instance: Article: Six seconds after its launch in Virginia, US, an unmanned rocket bound for the International Space Station (ISS) exploded, disappointing people both on Earth and in space. Hundreds of millions of dollars worth of cargo was destroyed in the Oct. 28 explosion due to An"equipment failure", said Orbital Sciences, the company hired by NASA for the resupply mission. The rocket was carrying a cargo ship loaded with 2,200 kilograms of supplies such as food, tools, parts, and experiments. Roughly a third of the cargo was a series of scientific investigations. Some of them were from high school students in the US. For example, 10 students from the Cristo Rey Jesuit College Preparatory School of Houston were conducting experiments about microgravity and put their samples on the rocket. "I know that failure is a part of science, but I really feel sorry for my students," science teacher Greg Adragna told the Houston, Chronicle . Astronauts at the ISS felt a more urgent disappointment, however. The cargo included 617kg of food. Now they will have to rely on supplies from a Russian launch on Oct. 29. Launched in 1998 and involving the US, Russia, Canada, Japan, and the member countries of the European Space Agency, the ISS is one of the most ambitious international collaborations in history. Currently, there are six astronauts at the station, five male and one female. Three are from Russia, two are from the US, and one is from Germany. They have lived together for about six months. The station gets regular resupplies from Earth, using unmanned spacecrafts. Food is always a big part of the supplies. Most of the food is frozen and ready to eat, and often tastes bad-somewhat like trying to eat when you have a heavy cold. To make space life better, however, scientists have made breakthroughs. Earlier this year, Russian astronauts managed to grow a variety of crops aboard the station. Next year they are going to try to grow rice and other plants. And, as transporting water to space is expensive, astronauts are looking for ways to recycle water. "Astronauts on board the ISS already drink water distilled from sweat and urine<) ," Russian news agency RIA Novosti reported. Is that the reason the astronauts were so disappointed not to get the water from the failed resupply mission, by any chance?
