I guess I'd better see a doctor." "Listen, you don't have to spend that kind of money," Mike replies. "There's a diagnostic computer at the corner drugstore. Just give it a urine sample and the computer will tell you what's wrong and what to do about it. It takes ten seconds and costs ten dollars, much cheaper than a doctor." 无用户答案[Reference Answer:So Mack collects a urine sample in a small jar and takes it to the drugstore. He deposits ten dollars and the computer lights up and asks for the urine sample. He pours the sample into the computer and waits.] Ten seconds later, the computer turns out a slip: You have tennis elbow. Soak your arm in warm water and avoid heavy activity. It will improve in two weeks.That evening while thinking how amazing this new technology was, Mack began wondering if the computer could be fooled. He mixed some tap water, a stool sample from his dog, urine samples from his wife and daughter, and some oil from his car. Mack hurries back to the drugstore, eager to check the results. He deposits ten dollars, pours in his mixture, and awaits the results.The computer prints the following:1. Your tap water is too hard. Get a water softener.2. Your dog has skin disease. Bathe him with anti-fungal shampoo.3. Your daughter has a cocaine habit. Get her into rehab.4. Your wife is pregnant... twin girls. They aren't yours. Get a lawyer.5. Your Volvo needs repair.6. And if you don't stop messing around, your elbow will never get better.。
