In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.
One example: Article: Homework can put you in a bad mood , 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
Solution is here: B
Explanation: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. So, B is the correct answer.

Now, solve this: Article: "Now I just don't believe that." Surely all of us, at some point, have watched a movie and thought: It's simply badly researched, or, the makers must think we're fools. If movies were completely scientifically accurate, they'd probably be as interesting as a Physics 101 lecture. In real life, there are no explosions in space, gas usually doesn't explode from a lit cigarette, and Bruce Willis / Jackie Chan / Will Smith would most likely be in a coma after getting kicked in the head. Recently, the British newspaper The Daily Telegraph ran a humorous piece on unconvincing tech moments from some top movies. Let's see what _ are all about. Telegraph writer Tom Chivers' first example is from the end-of-the-world movie Independence Day, in which a character comes up with a virus capable of destroying Windows, the computer system the alien spacecraft uses. "It's a good thing they didn't have Norton antivirus," jokes Chivers. It's just one case of a movie that takes a lot of license with its science. Another one Chivers mentions is from Star Wars, where glowing beams of light traveling through space look very impressive. The problem is that in space there are no air particles for the light to reflect off. In reality, they'd not be seen, which wouldn't look so cool on the big screen. Chivers' second piece of Star Wars nonsense is the sound the fighters make in the movies: " the bellow of an elephant mixed with a car driving on a wet road". But sound needs a medium to travel through, like air. In space, there wouldn't actually be any sound at all. Few people would deny that the mind-bending Matrix films make for great viewing, but for Chivers, the science in the movies is a little silly. And finally: as Chivers points out, DAN is not replaceable. But this bit of elementary genetics passed the makers of the 2002 Bond film Die another Day by. In the film the villain has "gene therapy" to change his appearance and his DNA, which is completely impossible.
