[問題]OG168

[chloemoney]

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.

先說一下我的思路，原題「給了一個統計數字，最後推出結論」
選項A...我覺得是說是統計數字的錯誤，「比較基礎不相同」
B，證據不足
C，無關
E，證據不足

想請問一下，以上的思路分析有沒有問題，還有關於選項D，他是不是和166的 D是相同的概念，只是提出了一個數據，但需要更多的information才能支持。還是，168題目是focus on violent crime,所以他的焦點不對呢？ 感謝哦.....

166. Last year the rate of inflation was 1.2 percent, but for the current year it has been 4 percent. We can conclude that inflation is on an upward trend and the rate will be still higher next year.

Which of the following, if true, most seriously weakens the conclusion above?
(A) The inflation figures were computed on the basis of a representative sample of economic data rather than all of the available data.
(B) Last year a dip in oil prices brought inflation temporarily below its recent stable annual level of 4 percent.
(C) Increases in the pay of some workers are tied to the level of inflation, and at an inflation rate of 4 percent or above, these pay raises constitute a force causing further inflation. (D) The 1.2 percent rate of inflation last year represented a ten-year low.
(E) Government intervention cannot affect the rate of inflation to any significant degree .

關於168的D，正如你所說的焦點放在nonviolent crime，所以根本是無關的論述

那166的D，我覺得不太一樣，他說1.2是十年最低，想要製造最低反彈就一定會持續上升的假象! 不像168是提出一個不相關的比較

答案 (A)
法案通過之後暴力犯罪年年下降,表示此法發揮作用,廢止可能暴力犯罪上升,所以弱化廢止能降低暴力犯罪的提案.
