问题     Until recently the opportunities for criminal activities on the Internet have been low. However, the volume of business done on the Internet is growing rapidly such as ordering books and other products and making money transactions. All this is creating temptations for hackers.
    Hackers are often young people who are interested in computers. They use them to move quietly to the Internet, looking for ways to break into computer’s systems run by banks, telephone companies and even government departments. They look for examples of credit cards and try to steal the numbers.
    Hackers rarely admit to a successful break-in. The first indication of a hacking may be when a customer discovers a wrong money transaction on a credit card account. It is harder to check on somebody misusing an online connection unless there is a massive download of information which would call the attention of the consumer.
In the last sentence of the paragraph, "somebody" refers to a______.
选项 A、customer
B、card user
C、hacker
D、bank clerk
答案C
解析 语义题。第三段讲的都是黑客的活动如何才会被发现，第二、三两句列举了两种情况，所以这里的somebody指的是黑客，故选C。
