Newspaper editorial:
In an attempt to reduce the crime rate, the governor is getting tough on
criminals and making prison conditions harsher. Part of this effort has been
to deny inmates the access they formerly had to college-level courses.
However, this action is clearly counter to the governor's ultimate goal,
since after being released from prison, inmates who had taken such courses
committed far fewer crimes overall than other inmates.
Which of the following is an assumption on which the argument depends?
A. Not being able to take college-level courses while in prison is unlikely
to deter anyone from a crime that he or she might otherwise have committed.
B. Former inmates are no more likely to commit crimes than are members of the
general population.
C. The group of inmates who chose to take college-level courses were not
already less likely than other inmates to commit crimes after being released.
D. Taking high school level courses in prison has less effect on an inmate's
subsequent behavior than taking college-level courses does.
E. The governor's ultimate goal actually is to gain popularity by convincing
people that something effective is being done about crime.
