单选题 Persons imprisoned for violent street crimes often commit the same crimes again after being released. Persons imprisoned for white-collar crimes such as receiving bribes or embezzlement, however, typically do not, after being released, repeat the crimes for which they have been imprisoned. It is fair to conclude that imprisonment, while it often fails to change the behavior of violent street criminals, does succeed in making white-collar criminals unwilling to repeat their crimes.
Which of the following, if true, would most seriously weaken the conclusion stated above?

A、 Statistics show that persons convicted of committing white-collar crimes rarely have a prison record.
B、 The percentage of those who commit white-collar crimes and are imprisoned for doing so is lower than the percentage of those who commit violent street crimes and are imprisoned for doing so.
C、 White-collar criminals whose prison sentences are shortened return to criminal activities at a slightly higher rate than white-collar criminals who serve their full sentences.
D、 Persons released from prison after white-collar crimes are seldom given high positions or access to other people's money.
E、 (E) Persons who commit violent street crimes seldom commit white-collar crimes, and vice versa.

【正确答案】 D

【答案解析】[解析] 本题推理比较简单，由一个事实而得出一个解释性结论：坐牢能使白领不愿再次犯罪。反对思路多为“有他因”。(D)指出白领犯罪之后被从监狱释放出来难以再次得到能使他们重新犯罪的机会，对上面的事实就做出了另外一个解释，所以起到了反对作用，因此(D)正确。(A)起到了部分支持作用；(B)做的无关比较与段落推理无关；(C)也不能解释上面事实；(E)也为无关选项。
