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?
黑体其实最好做的,你关注一下两端boldface之间有没有转折关系,这样一般就可以排除剩2个,然后再比较一下选项~举个例子

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.
E The first is a generalization about the likely effect of a policy under consideration in the argument; the second points out a group of exceptional cases to which that generalization does not apply.
你会发现两个黑体之间有however,说明是反向的关系,可以排除ADE,然后对比BC,main conclusion明显不对排除C,所以就B了,一般就是现有Boldface之间but however...之类的转折词判定两者关系,然后在对比剩余选项,一般要对比的也就claim conclusion evidence之类的~
