: 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.
1.政府藉由更嚴的政策減低犯罪率-->2.也減低了囚犯參加course的機會
3.參加course可以減低犯罪率-->推論:因為2所以沒辦法達到1
要讓推論成立,則關鍵的是3必須成立
選項C-->會參加course的囚犯並非本來就不容易再犯罪
取非C-->參加course的囚犯本來就不容易再犯罪-->3不成立-->推論不成立
