Problem: 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.

Problem: Article: If a business wants to sell its products internationally, it had better do some market research first. This is a lesson that some large American corporations have learned the hard way. What's in the name? Sometimes the problem is the name. When General Motors introduced its Chevy Nova into Latin America, it overlooked the fact that Nova in Spanish means "It doesn't go". Sure enough, the Chevy Nova never went anywhere in Latin America. Translation problems Sometimes it is the slogan that doesn't work. No company knows this better than Pepsi-Cola, with its "Come alive with Pepsi!" campaign. The campaign was so successful in the United States , Pepsi translated its slogan literally for its international campaign. As it turned out , the translations weren't quite right. Pepsi was begging Germans to "Come out of the grave " and telling the Chinese that "Pepsi brings your ancestors back from the grave." A picture's worth a thousand words Other times, the problem involves packaging . A picture of a smiling baby has helped sell countless jars of Gerber baby food. When Gerber started selling baby food in Africa, they used the same packaging as in the US, with the smiling baby on the label. Later they learned that in African countries, the picture on the jar shows what the jar has in it, for many people there can't read. Twist of fate Even the culture and religious factors and pure coincidence can be involved. Thorn McAn shoes have a Thorn McAn "signature" inside. To people in Bangladesh, which is a Muslim country, this signature looked like Arabic script for the word Allah. In that country, feet are considered unclean, and Muslims felt the company was offending God's name by having people walk on it.
Question: From the text we learned that _ .
Options: (A) Chevy Nova was brought in Latin America (B) General Motors did the best market research of all companies (C) Pepsi still sold well in China owing to the translation problems (D) the "Come alive with Pepsi" campaign worked well in the US
Solution:
D
