OG-168怎么理解？

QHDMBA

168. In the United States in 1986, the average rate of violent crime in states with strict gun-control laws was 645 crimes per 100,000 persons—about 50 percent higher than the average rate in the eleven states where strict gun-control laws have never been passed. Thus one way to reduce violent crime is to repeal strict gun control laws.

Which of the following, if true, would most weaken the argument above?

(A) The annual rate of violent crime in states with strict gun-control laws has decreased since the passage of those laws.

(B) In states with strict gun-control laws, few individuals are prosecuted for violating such laws.

(C) In states without strict gun-control laws, many individuals have had no formal training in the use of firearms.

(D) The annual rate of nonviolent crime is lower in states with strict gun-control laws than in states without such laws.

(E) Less than half of the individuals who reside in states without strict gun-control laws own a gun.

怎么枪械管制的地方的暴力犯罪率还要比没有管制的地方高50%？枪械管制怎么能减少暴力犯罪呢？

我选A

因为有的州的暴力犯罪率高，所以需要gun-control law。A说有了这项法令之后，这些州的暴力犯罪率下降了，说明这项法令可以降低犯罪率，直接weaken原结论。

the average rate of violent crime in states with strict gun-control laws was 645 crimes per 100,000 persons是指枪械管制之前的情况吗？费解。

同意楼上的说法呵呵

绝对数并不能说明问题，而且就这题而言其他选项都有无关词，通过排除法可以解决这个问题

Ruisseau

应该是管制之后的情况

管制有没有效果是对施行管制的州前后而言的

我觉得可以不考虑没有施行管制的州，因为在没有管制之前的州与未施行管制的州的暴力犯罪率是未知的，没有可比性

原来repeal是废除的意思，理解错了，造成整个题目的误解。汗颜
