Q: 请教LSAT-Set5-SecII-Q22
22. Public reports by national commissions, governors’ conference, and leadership groups have stressed the great need for better understanding of international affairs by the citizenry. If the country is to remain a leading nation in an era of international competitiveness, the need is undesirable. If there is such a need for the citizenry to have a better understanding of international affairs, then all of our new teachers must be prepared to teach their subject matter with an international orientation.
If all of the statements in the passage are true, which one of the following must also be true?
(A) If the country is to remain a leading nation in an era of international competitiveness, then new teachers must be prepared to teach their subject matter with an international orientation.
(B) If new teachers are prepared to teach their subject matter with an international orientation, then the country will remain a leading nation in an era of international competitiveness.
(C) If there is better understanding of international affairs by the citizenry, then the country will remain a leading nation in an era of international competitiveness.
(D) If the country is to remain a leading nation in an era of international competitiveness, then there is no need for the citizenry to have a better understanding of international affairs.
(E) Public reports from various groups and commissions have stressed the need for a more international orientation in the education of teachers.

答案A，为何不是D？请大家指教。

A:   
记得当时也做错了,hehe。关键是undesirable的理解，如果解释为不可取的，则答案为D,但明显与客观事实不符。后来解释为不乐观的，则A就顺理成章，a-->b, b-->c, 则a-->c.
偶觉得这样解释太牵强。查过韦氏undesirable：not desirable : UNWANTED别无他义。怎么里解更合理呢？在法律方面有特殊意义？牛牛们给些指点吧？

Q: 请教LSAT-Set5-SecII-Q3

3.In Europe, schoolchildren devote time during each school day to calisthenics. North American schools rarely offer a daily calisthenics program. Tests prove that North American children are weaker, slower, and shorter-winded than European children. We must conclude that North American children can be made physically fit only if they participate in school calisthenics on a daily basis.

Which one of the following is assumed in the passage?

(A) All children can be made physically fit by daily calisthenics.

(B) All children can be made equally physically fit by daily calisthenics.

(C) Superior physical fitness produces superior health.

(D) School calisthenics are an indispensable factor in European children’s superior physical fitness.

(E) North American children can learn to eat a more nutritious diet as well as to exercise daily
答案是 B,但偶觉得 D应该也对啊

the need is undeniable我理解为这种需要是无可否认的。

提干前2句= if country remain leading position (1)==>need for better understanding inter affair (IA) (2)

第3句，(3) if need a better understanding IA==>(4) all teacher can teach subject matter with international orientation.

(2) =(3), so (1)==>(4)即位A.

D不是答案，除非把no去掉。

Q3是不是你把答案看错了。答案应该是D. 原文提干反复前掉的事一个必要条件：north American school rarely offer, ... North American children are weaker, 没有这个必要条件，则没有结果 - strong. 最后以句only if 也指向必要条件。

今天刚做完这套。。讨论讨论。。
1。我也选了D，我觉得A根本无法推出。。

"the need is undeniable我理解为这种需要是无可否认的。"   mzyzhu, 你看错了吧？ 是undesirable不是undeniable

2。答案是D。。我刚做完对的答案。。。恭喜恭喜，你又做对了一道。

不好意思，真的看错答案了

我说一道简单的题为什么老有人讨论，原来是电子版惹得祸。

undeniable来源黄皮书，undesirable来源elasat.

电子版在带来方便的同时也带来不少麻烦。类似这样的错误还不少，所以我做题只用黄皮书。在复习是我还发现电子版竟然有整句话省略的情况。估计是在极度缺乏睡眠的情况下录入的

oh!!!
So this is the cost of free material....
Thank you, mzyzhu..
