单选题 What is this passage mainly about?

A. The difference between classical music and rock music.
B. Why classical music is popular with math students.
C. The effects of music on the results of math tests.
D. How to improve your reasoning ability.

【正确答案】 C

【答案解析】[解析] 10-12 Do you have a tough math test coming up? Then listen to some classical piano music just before the test. You might end up with a higher score. Researchers at a university in California conducted an experiment. They asked a group of college students to listen to some piano music by a famous 18th century composer before taking a math test. They were surprised to find that the students' scores jumped 8 to 9 points. The music seems to excite nerve activities in the brain; similar to the activity that occurs when a person is figuring out a math problem. However, the scientists warn before you get too excited about applying this method to your math test, you should remember that the brain-exciting effects last only 10 or 15 minutes. Would rock music work as well as piano music? No, the scientists say. In fact, the less complex music might even interfere with the brains' reasoning ability. 10. What is this passage mainly about?
