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.
