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

New input: Article: Robots make me nervous-especially the ones which seem to think for themselves.I was embarrassed to admit this till I heard that Bill Gates,the founder of Microsoft,felt the same way.Gates said in an interview with the website Reddit:"I am in the camp that is concerned about super intelligence.First the machines will do a lot of jobs for us and not be super intelligent.That should be positive if we manage well.A few decades after that though the intelligence is strong enough to be a concern." Well,maybe I don't have to worry about my laptop and kitchen appliances yet.After I use them I can always pull the plug.But in the future,machines might find a way to prevent us from switching them off.There's a scary thought! Professor Stephen Hawking warned a few months ago about the possibility that artificial intelligence could evolve and end up beyond human contro1.He suggested that machines could" _ the end of the human race". Maybe the problem with computers too clever for us is not that they are evil or rebellious.What could put us in danger is that they might be too efficient.That's what philosopher Nick Bostrom from the Future of Humanity Institute at Oxford University believes.He says that machines are indifferent to humans and in pursuit of their own goals,the destruction of people might be just collateral damage.A machine would not take pity on you. I'm glad my machines at home are"dumb".All my vacuum cleaner wants to take over is the carpet in my living room.Let's hope they don't create an appliance which wants to take over the world!
Question: We can conclude from Gates'statements that _ .
Options: (A) he is embarrassed that he is afraid of robots (B) he doesn't think machines are intelligent (C) machines should be fully employed (D) machines'super intelligence should be a concern
Asnwer: D
Solution:
Yes
