Read the following article and select the best answer. Article: It's hard to avoid looking like a fool on April Fool's Day. On April 1 each year, people play tricks on each other. These tricks are usually silly rather than mean. Classmates sometimes tie each other's shoelaces to their chairs.Teachers might hand out an impossibly difficult surprise test that scares students before they realize it's only a joke. Newspapers announce fake contests (such as "Win an elephant!") and report on fake stories (like "UFO" lands in New York City). Forget gifts, songs and special foods--those are for the other holidays of the year. On April Fool's Day, the only tradition is to laugh (and maybe to cause a little bit of trouble). One April Fool's Day, when I was in high school, a group of students in my class played a very clever and funny trick on the teachers. They bought some chickens and set them free in our school cafeteria. The chickens ran all round the school, in and out of classrooms and under our feet. Feathers were flying everywhere. Teachers began running after the chickens, trying to catch them. Finally, they caught four of them. But the chickens were wearing numbered tags around their necks, and the teachers discovered that they had only caught chickens No.1, 2, 3, and 5.Where was chicken No.4? The teachers looked and looked. They couldn't find another chicken. After a few hours, they realized that the students had played another joke on them: There were only four chickens in the first place! They've been tricked by the numbers on the chickens. It's been a long time since I was in high school, but that April Fool's Day remains one of my favorite memories from those years. Question: How many jokes did the students play on teachers? - One. - Two. - Three. - Four.
(A).
Two.

Read the following article and select the best answer. Article: Does solving a math problem give you a headache? Do you feel nervous when you sit a math exam? For most students, math can be tough but scientists have proved that math problems can actually trigger physical pain. Scientists came to his conclusion with an in-depth experiment, which was published in the Public Library of Science One journal. They began by finding out how much participants fear math. Those involved were asked a series of questions such as how they feel when they receive a math textbook or when they walk into a math lesson. Based on their answers, participants were divided into groups. One group was made up of people who were particularly afraid of math and participants in the other group were more comfortable with the subject. Both groups were then given either math tasks or word tasks. When a math task was going to come next, a yellow circle would appear but when a word task was soon to come, a blue square would be shown. Using a brain-scan machine, scientists noticed that whenever people from Group One saw a yellow circle, their brain would respond in a way similar to when their body is feeling pain. It was like the pain they would fee, for example, if they burnt their hand on a hot stove. But they reacted less strongly when they knew that they would be faced with a word task. However, scientists saw no strong brain response from people in the second group. Math can be difficult, and for those with high levels of mathematics-anxiety (HMA), math is associated with tension, apprehension and fear. "When you are really thinking about the math problems, your mind is racing and you are worrying about all the things that could go wrong," explained Ian Lyons from University of Chicago, US, leader of the study. "The higher a person's anxiety of a maths task, the more he activated brain regions associated with threat detection, and the experience of pain." More interestingly, the brain activity disappeared when participants actually started dealing with the math tasks. "This means that it's... Question: What can be concluded from the experiment? - The anticipation of math has no relation to students' confidence in math. - Moderate mathematic anxiety promotes students' academic performance. - Physical pain caused by HMA disappears in the process of doing math problem. - Effective solutions have been worked out to lower students' anxiety of math.
(A).
Physical pain caused by HMA disappears in the process of doing math problem.

Read the following article and select the best answer. Article: "He was a nightmare ," his mother, Mary said as I talked with her and her son Jamie. "I was sure he was going to end up in prison, or worse". Seeing Jamie so full of life with his new friends, there was no room for imagination that he was ever a rebellious kid.

Mary didn't realize the result of the trouble Jamie made until he told her he had been stopped from going to school for three weeks. Mary was very angry, but now she has realized that it was the best thing that had happened to both of them.

"They were so cool and able to express themselves in a way I had never seen before. I asked to join them and they agreed. Because of them I am who I am now." Jamie told me, tears in his eyes. Back at school, his whole attitude and behavior improved. "I realized the boys I was hanging out with weren't cool, stealing wasn't cool and getting out of school wasn't cool either. It made me find something I love and have a goal in life." he said. Yes, street dance makes him happy. This kind of dance speaks to people, and gives them a purpose.
