24. The interstitial nucleus, a sub-region of the brain’s hypothalamus, is typically smaller for male cats than for female cats. A neurobiologist performed autopsies on male cats who died from disease X, a disease affecting no more than .05 percent of male cats, and found that these male cats had interstitial nuclei that were as large as those generally found in female cats. Thus, the size of the interstitial nucleus determines whether or not male cats can contract disease X.
Which one of the following statements, if true, most seriously weakens the argument?
A. No female cats have been known to contract disease X, which is a subtype of disease Y.
B. Many male cats that contract disease X also contract disease Z, the cause of which is unknown.
C. the interstitial nuclei of female cats who contact disease X are larger than those of female cats who do not contract disease X.
D. Of 1,000 autopsies on male cats that did not contract disease X, 5 revealed interstitial nuclei larger than those of the average male cat.
E. The hypothalamus is known not to be causally linked to disease Y, and disease X is a subtype of disease Y.
答案是E,可以理解,但是D为什么不对呢?
是因为文中说的 whether or not male cats can contract disease X. 并没有表示一定大就一定会得的意思?
29. The price of a full-fare(全票价) coach ticket from Toronto to Dallas on Breezeway Airlines is the same today as it was a year ago, if inflation is taken into account by calculating prices in constant dollars. However, today 90 percent of the Toronto-to-Dallas coach tickets that Breezeway sells are discount tickets and only 10 percent are full-fare tickets, whereas a year ago half were discount tickets and half were full-fare tickets. Therefore, on average, people pay less today in constant dollars for a Breezeway Toronto-to-Dallas coach ticket than they did a year ago.
Which one of the following, if assumed, would allow the conclusion above to be properly drawn?
(A) A
(B) A
(C) All full-fare coach tickets on Breezeway Airlines cost the same in constant dollars as they did a year ago.
(D) The average number of coach passengers per flight that Breezeway Airlines carries from
(E) The criteria that Breezeway Airlines uses for permitting passengers to buy discount coach
答案选B,我没有怎么弄懂文章意思,if inflation is taken into account by calculating prices in constant dollars是什么意思?
考虑了通货膨胀之后的实际价格吗?即一年前100元,现在200元,但因为通过膨胀了100%,所以实际价格不变的意思吗?
那么B,C选项怎么判断?
原价不变和打折后不变,有什么区别?
45. Commissioner: Budget forecasters project a revenue shortfall of a billion dollars in the coming fiscal year.
Since there is no feasible way to increase the available funds, our only choice is to decrease expenditures. The plan before you outlines feasible cuts that would yield savings of a billion dollars over the coming fiscal year. We will be able to solve the problem we face, therefore, only if we adopt this plan.
This reasoning in the commissioner’s argument is flawed because this argument
A. relies on information that is far from certain
B. confuses being an adequate solution with being a required solution
C. inappropriately relies on the opinions of experts
D. inappropriately employs language that is vague
E. takes for granted that there is no way to increase available funds
答案选B
宝典上的分析为:
思路:年度财务预算下一财年收入不足量one billion dollars,由于没有feasible way增加可得资金,只有削减开支。因而只是做了一个如何之间节省10亿美金的计划,it is just a required solution but not adequate maybe.
而我觉得意思刚好相反,是一个adequate solution, 但不是required solution(必须)。 only if 后面表示必要条件
请大家帮忙分析一下,十分感激!!

答案是E,可以理解,但是D为什么不对呢?(文中说1,000 autopsies 中有五个和femal一般大,所以得出the size of the interstitial nucleus determines whether or not male cats can contract disease X.的结论,d选项说有五个男猫的 interstitial nuclei比男猫平均大,根本就没有削弱原文根据男猫和女猫的比较得出的结论,所以是无关选项 )
是因为文中说的 whether or not male cats can contract disease X. 并没有表示一定大就一定会得的意思?

,但是他文章并没有讲折扣的比利时多少,所以应该还要比较折扣后的价格,这就是文章的解体思路,如果现在折扣后的价格和原来折扣后的价格一样,但是现在享受的折扣的percent多与去年,所以...)

我觉得按照only if 的字面意思理解“只有“的话,b的解释的确有问题,adopt this plan只是 solve the problem 的必要条件,不能保证其成立,请大侠解或,因为新东方老师也说only if 表后面的是必要条件
非常感谢!!
24,29我明白了,谢谢!
45我认为答案解释可能有一些偏差
we adopt this plan应该是We will be able to solve the problem we face的充分条件,而不是必要条件
24题 B选项,可以认为是他因削弱吗?(由Z引起,而非X)
