参考答案【正确答案：B】
推断题。作者在第一段第二句指出，为了私人目的而更改机器中的信息的人能够得到可观的回报。在第四段举了两例计算机犯罪都是经济犯罪，从这些信息可以推断出，计算机犯罪在金融机构很严重，因此B项“计算机犯罪在金融机构的运营中是个很严重的问题”为正确答案。A项“现在计算机犯罪仍然无法查出”，这与第二段第一句话不符，本句话说：如果没有人检查计算机的工作，计算机犯罪就很难被发觉。换句话说，只要有人检查，计算机犯罪是可以查出来的。C项“计算机犯罪分子能够脱逃惩罚，因为查不出来”，错误之处和A项一样。D项“一些人应公司的要求进行计算机犯罪活动”，文章中没有内容支持，属于典型的无中生有。
