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: Cob is a six-year-old boy. An aid organization brought him to the farm run by Joy from another province. Both Cob's parents died of serious disease when he was a two-month-old baby. His eighty-year-old grandmother treated him badly. He developed a disease over time, which led to him being unable to keep things in mind well; on the other hand, there was nothing good for him to bear in mind as well. When he first arrived at the farm, it appeared to him like a huge playground. Cob plyed around, hid behind trees and bushes, and enjoyed this new area. Over time, he gained confidence, chose Joy as his new mother, and let her carry him around. Amy, Joy's real daughter, the same age as Cob, had to learn to share her mother with the other child. She also needed to see the other children as her brothers or sisters and accept them although she may be unwilling to do so. In the beginning, Cob did not use the facilities on the farm. Slowly Joy tried to help him use them and during the day, he kept on with them but not at night. All attempts to send him to school failed. As soon as he arrived there, he ran off into the wide world like a free rabbit. He enjoyed running around in school rather than doing what teachers told him to do. Finally, the head teacher announced that the school was not suitable for Cob. Cob had to go back to the farm. At daytime, he watched adults and elder children bicycle and if there was any chance, he took a bicycle, then pushed and pulled it up and down the hill. One day Cob found there was a small bicycle standing next to the big ones. It was a gift for him! It was new with wheels on each side of the back wheel, which was just right for a little child without any experience in riding a bicycle. Cob pushed it up the hill, got on it and off from time to time. From then on Cob began riding his bicycle every day. Although he often fell and got hurt, he went on. During rainy days, he stored the bicycle in his room and slept close to it at night. Maybe even in his dreams he was happy -- he had found the entrance to a happy and satisfying life.
Question: Upon being taken to the farm, Cob felt _ .
Options: (A) confused (B) frightened (C) annoyed (D) excited
