參考答案【正確答案：B】
推斷題。作者在第一段第二句指出，為了私人目的而更改機(jī)器中的信息的人能夠得到可觀的回報(bào)。在第四段舉了兩例計(jì)算機(jī)犯罪都是經(jīng)濟(jì)犯罪，從這些信息可以推斷出，計(jì)算機(jī)犯罪在金融機(jī)構(gòu)很嚴(yán)重，因此B項(xiàng)“計(jì)算機(jī)犯罪在金融機(jī)構(gòu)的運(yùn)營(yíng)中是個(gè)很嚴(yán)重的問題”為正確答案。A項(xiàng)“現(xiàn)在計(jì)算機(jī)犯罪仍然無法查出”，這與第二段第一句話不符，本句話說：如果沒有人檢查計(jì)算機(jī)的工作，計(jì)算機(jī)犯罪就很難被發(fā)覺。換句話說，只要有人檢查，計(jì)算機(jī)犯罪是可以查出來的。C項(xiàng)“計(jì)算機(jī)犯罪分子能夠脫逃懲罰，因?yàn)椴椴怀鰜怼?，錯(cuò)誤之處和A項(xiàng)一樣。D項(xiàng)“一些人應(yīng)公司的要求進(jìn)行計(jì)算機(jī)犯罪活動(dòng)”，文章中沒有內(nèi)容支持，屬于典型的無中生有。
