狒狒笔记中一题，大家来给个答案吧～～

 Because incumbent members of Congress are given a great deal of attention by the news media

and because they enjoy such perquisites as free mail privileges and generous travel allowances,

incumbents enjoy an overwhelming advantage over their challengers in elections for the United

States Congress.

  Which of the following, if true, best supports the claim above?

(A) In the last congressional elections, incumbents met with a larger number of lobbyists than did

challengers.

(B) In the last congressional elections, 98 percent of the incumbents in the House of Representatives

who were seeking reelection won.

(C) Incumbent members of Congress are frequently critical of the amount of attention given to them

by the news media.

(D) The support that political station action committees provide to challengers for congressional seats       often compensates for the perquisites enjoyed by incumbent members of Congress.

(E) Of all incumbent senators surveyed before the last congressional elections, 78 percent said that

their challengers did not pose a serious threat to their chances for reelection.

D答案是一位NN给的，不过我始终觉得还是应该选B，大家来讨论一下这题的答案吧

发表不同意见

支持E

B：House of Representatives ？United States Congress is disscussed in the argument.

D：一个委员会支持challenger的同时，弥补了incumbents以额外的补贴，即说明challenger也有被支持，因此overwhelming advantanges will be undermined since it seems that the balance is set between the challengers and incumbents.

E: theme is the congress and 78% senators are equal to the "overwhelming " advantages.

       Scientists now believe that artificial-hip implants, previously thought to be safe, may actually

increase the risk of cancer in recipients after about 45 years of use. Though these implants do

improve the quality of recipient’s lives, the increased risk of cancer is an unacceptable price to pay

for these improvements. Therefore, they should be banned.

  Which of the following, if true, is the strongest counterargument to the argument above?

(A) Artificial-hip implant surgery can cause severe complications, such as infection, chronic fever, and bone degeneration, and these complications can themselves be crippling or even fatal.

(B) Almost all artificial-hip implant recipients receive their implants at an age when they are unlikely to live more than an additional 30 years.

(C) Although artificial-hip implants increase the risk of cancer after about 45 year of use, a few of

the cancers they induce are not fatal.

(D) Since artificial-hip implants are not very common, banning them would cause little hardship.

(E) Although the benefits of artificial-hip implant surgery have remained substantially the same over

the past decade, the price of the surgery has risen considerably.

这题网上给的答案是C，可我觉得C不对，B才对呀，C的意思说还是会有很多cancers are fatal的呀

例3. Since 1945 there have been numerous international confrontations as tense as those that precipitated

the Second World War, and yet no large-scale conflict has resulted. To explain this, some argue that

fear of enormous destruction such as the Second War produced has had a dramatic deterrent effect.

  Which of the following, if true, most seriously weakens the deterrent theory mentioned above?

(A) After the First World War, the fear of great future destruction was as intense as it was after the Second World War.

(B) Psychologists have determined that the fear of retaliation tends to temper aggressiveness among

human beings.

(C) The Second World War was far less distractive than most people generally believe.

(D) Fear of repeating the levels of destruction that the Second World War produced is as pervasive

today as it was forty years ago.

(E) Many of the international confrontations that have occurred since 1945 have involved countries

that participated in the Second World War.

这题答案给的C，我就实在想不通了，觉得是A

你看的是什么答案啊,真是一塌糊涂.我认为,你的观点是对的.

俺来说说俺的想法，请指正：

我觉得B的毛病在于：原题的主要论点是卫冕者有advantage，B讲了卫冕者胜率高，但是未必是因为他们的advantage;

E同样有这个毛病，卫冕者说挑战者威胁不到他们，这也不能证明卫冕者就有advantage

D里面明确有了perquisites enjoyed ， 也就是说advantage确实存在。

我这么理解对么？

另外两道题，俺跟楼主想得一样。。。

For the first question, D is not right because it weakens the arguement.

I would choose A instead.

The congress members have more chance to see more lobbyists. Don't forget that behind the lobbyists are the wealthy companies and individuals who want the congress members to vote in their favor in the future.  It sound complicated, but that is the only purpose of the lobbyists. It is obvious then, that the incumbents will get more money for their campaign. To be sure, fund raising is an important factor comtributing to the outcome of the election, right?

 I also agree to the two answers given by LZ for the other two questions.
