单选题 Why shouldn't we use a word that can be found in any dictionary as a password?

A、 Because it can be easily remembered by a computer hacker.
B、 Because computer programs can crack it.
C、 Because computer hackers are determined to crack it.
D、 Because the lists are so huge that the words are not easy to remember.

【正确答案】 B

【答案解析】本题答案的出处在第三段的最后三句话。文中指出语言中的词容易在词典里被查出。最后一句Programs can test for variations of these words暗示并与本段的开头两句呼应——“如果可能，不要用由字母和数字组成的密码。比较简单的计算机程序能够很快地破译这类密码。”
