【正确答案】
C
【答案解析】[听力原文] Elder is an assistant professor of marketing at Brigham Young University's Marriott School of Management. He says that if people notice the sound the food makes as they eat it, they may eat less. On the other hand, watching loud television or listening to loud music while eating can hide such noise. And this could lead to overeating. For the study, the researchers wanted to test whether the sounds of eating-chewing, chomping and crunching—had any effect on how much a person ate. During the experiments, the test subjects wore headphones and listened to noise at either a high or a low audio level. Then researchers gave them a crunchy snack: pretzels. The study found that subjects who listened to the higher volume noise ate more pretzels than those with the low audio levels. Elder says that when hiding the sounds of eating, like when you watch television or listen to loud music while eating, we take away the sense of hearing. And this may cause you to eat more than you would normally. On what would Elder agree? 新闻开头简单介绍了埃尔德，随后指出，他称，如果人们能注意到自己吃东西时发出的声音，他们可能会吃得少一些，由此可见，C项是埃尔德赞同的观点，故本题选C。
