求教 GWD-4-27 governor problem

Q27:

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 form 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?

1. 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.
2. Former
        inmates are no more likely to commit crimes than are members of the
        general population.
3. 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.
4. Taking
        high school level courses in prison has less effect on an inmate’s
        subsequent behavior than taking college-level courses does.
5. The
        governor’s ultimate goal actually is to gain popularity by convincing
        people that something effective is being done about crime.
