11.GWD-19-Q30

Criminologist:  Some legislators advocate mandating a sentence of life in prison

for anyone who, having twice served sentences for serious crimes, is subsequently

convicted of a third serious crime.  These legislators argue that such a policy

would reduce crime dramatically, since it would take people with a proven tendency

to commit crimes off the streets permanently.  What this reasoning overlooks,

however, is that people old enough to have served two prison sentences for serious

crimes rarely commit more than one subsequent crime.  Filling our prisons with such

individuals would have exactly the opposite of the desired effect, since it would

limit our ability to incarcerate younger criminals, who commit a far greater

proportion of serious crimes.

In the argument as a whole, the two boldfaced portions play which of the following

roles?

A.      The first is a conclusion that the argument as a whole seeks to refute; the

second is a claim that has been advanced in support of that conclusion.

B.       The first is a conclusion that the argument as a whole seeks to refute;

the second is the main conclusion of the argument.

C.      The first is the main conclusion of the argument; the second is an

objection that has been raised against that conclusion.

D.      The first is the main conclusion of the argument; the second is a

prediction made on the basis of that conclusion.

我也觉得B没有错，但是当时也觉得E是对的。想问一下E为什么错了呢？谢谢~

e中其实这一句What this reasoning overlooks, however, is that people old

enough to have served two prison sentences for serious crimes rarely commit more

than one subsequent crime.才是 points out a group of exceptional cases to which

that generalization does not apply.

 我居然两次都选了C...

究其原因是分不清conclusion和main conclusion.关于这个问题，大家有什么好建议吗？或者

仅仅对这道题分析下也好。

谢谢！
