以下是引用5332649在2004-2-19 17:49:00的发言:各位大侠, 请教: 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. B 为何不对,有此条件,原因推不出结果
To weaken, Premise: a fact that avg rate with restrict gun's status higher than without restrict gun's. A: repeal restrict gun's law B: reduce crime. A->B. To weaken, not A. Current status is desceing the avg rate of crime. thus, Choice A is the best. Regarding Choice B, few individuals are prosecuted --> law is effected. Any relationship with the avg rate of crime? Pls don't 联想. |
