D. all the above
Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little more than one second to be affected.
An American scientist has found that using aspirin (阿斯匹林) increase the temporary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.
The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.

Do you know of anyone who uses the truth to deceive (欺骗)? When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture.
For example, someone might say, I just won a hundred dollars on the lottery (彩票). It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!
This guy's a winner, right? Maybe, maybe not. We then discover that he bought $ 200 worth of tickets, and only one was a winner. He’s really a big loser!
He didn’t say anything that was false, but he left out important information on purpose. That’s called a half-truth. Half truths are not technically lies, but they are just as dishonest.
Some politicians often use this trick. Let’s say that during Governor Smith’s last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents (对手) says, “During Governor Smith’s term, the state lost one million jobs!” That’s true. However, an honest statement would have been, “During Governor Smith’s term, the state had a net gain of two million jobs.”
Advertisers (广告商) will sometimes use half-truths. It’s against the law to make false statements so they try to mislead you with the truth. An advertisement might say, “Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.” It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.
This kind of deception happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.
