问题    In many businesses, computers have largely replaced paperwork, because they are fast, flexible, and do not make mistakes. As one hanker said, "Unlike humans, computers never have a bad day." And they are honest. Many banks advertise that their transactions are "untouched by human hands" and therefore safe from human temptation. Obviously, computers have no reason to steal money. But they also have no conscience, and the growing number of computer crimes shows they can be used to steal.
   Computer criminals don’t use guns. And even they arc caught, it is hard to punish them because there are no witnesses and often no evidence. A computer cannot remember who used it: it simply does what it is told. The head teller at a New York City Bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this theft because he moved the money from one account to another. Each time a customer he had robbed questioned the balance in his account, the teller claimed a computer error, then replaced the missing money from someone else’s account. This man was caught only because he was a gambler. When the police broke up an illegal gambling operation, his name was in the records.
   Some employees use the computer’s power to get revenge on employers they consider unfair. Recently, a large insurance company fired its computer-tape librarian for reasons that involved her personal rather than her professional life. She was given thirty days’ notice. In those thirty days, she erased all the company’s computerized records.
   Most computer criminals have been minor employees. Now police wonder if this is "the tip of the iceberg". As one official says, "I have the feeling that there is more crime ont there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing—the ones who really know how a computer works."
What can we infer from the passage?
选项 A、Minor employers are more likely to commit crimes.
B、Crimes committed by computer experts are difficult to detect.
C、Computer criminals are usually from the cold regions.
D、There are too many criminals for the police to catch.
答案B
解析 从全文来看，尤其是第二段首句给了很多的提示。计算机犯罪者因为在审判时没有证人也没有证据而逍遥法外，也就是电脑专家犯下的罪行很难被侦察。
