Conclusion: Therefore, given that a price that will prove to be right is virtually impossible for the seller to gauge in advance, the seller should make sure that any error in the initial asking price is in the direction of setting the price too high.
Question: The argument recommends (a certain pricing strategy ) (on the grounds that)
R: A certain pricing strategy which the argument recommends is high pricing because of trying to sell such an item fast by asking too low a price is a serious error, since it calls into question the very thing---exclusivity---that is supposed to be the item’s chief appeal.
==> A : this strategy lacks a counterproductive feature of the rejected alternative. We can see, anwer A summarize the premise,that is the reason.

Certain items—those with that hard-to-define quality called exclusivity—have the odd property, when they become available for sale, of selling rapidly even though they are extremely expensive. In fact, trying to sell such an item fast by asking too low a price is a serious error, since it calls into question the very thing---exclusivity---that is supposed to be the item’s chief appeal. Therefore, given that a price that will prove to be right is virtually impossible for the seller to gauge in advance, the seller should make sure that any error in the initial asking price is in the direction of setting the price too high.
The argument recommends a certain pricing strategy on the grounds that
(A) this strategy lacks a counterproductive feature of the rejected alternative
(B) this strategy has all of advantages of the rejected alternative, but fewer of its disadvantages
(C) experience has proven this strategy to be superior, even though the reasons for this superiority elude analysis
(D) this strategy does not rely on prospective buyers estimates of value
(E) the error associated with this strategy, unlike the error associated with the rejected alternative, is likely to go unnoticed

19. Need a bridge: But it is unrealistic to expect such measures to compensate for pilots’lack of actual flying time.--> Therefore, the airlines should rethink their training approach to reducing commercial crashes . That is :
pilots’lack of actual flying time is one of the reasons of commercial crash.
==> D correct?
11: zhy79 's explaination is good.
biologist:如果森林继续恶化,koala将消失 ( D--> E)
politivian:所以我们只需阻止森林恶化,就能防止koala消失( ~D --> ~E)
according to logical structure, we know there are different.
Question: Which one of the following statements is (consistent with the biologist’s claim but not with the politician’s claim?)
So: B:如果森林(delete继续)恶化stop ,koala(delete将)消失.Not comsistent with Politivian's claim.
11题我明白了,
第19题,我凭理解C、D、E的意思,觉得应该选D,但是如果用我题的那种“取非则结论不成立”就有点确定不了,不过想想也对,如果原来是strengthen的,取非后就有可能影响结论的成立,但我觉得这题的直接结论应该是such measures do not compensate for pilots’lack of actual flying time,而therefore 后的内容是间接结论。

“If the forest continues to disappear at its present pace, the koala will approach extinction,” said the biologist.
“So all that is needed to save the koala is to stop deforestation,” said the politician.
Which one of the following statements is consistent with the biologist’s claim but not with the politician’s claim?
(A) Deforestation continues and the koala becomes extinct.
(B) Deforestation is stopped and the koala becomes extinct.
(C) Reforestation begins and the koala survives.
(D) Deforestation is slowed and the koala survives.
(E) Deforestation is slowed and the koala approaches extinction.
biologist:如果森林继续恶化,koala将消失
politivian:所以我们只需阻止森林恶化,就能防止koala消失
B:森林不恶化,koala消失
与biologist不矛盾:因为原文只说如果森林继续恶化,koala将消失
但没说如果森林不恶化,koala就不消失

How do the airlines expect to prevent commercial plane crashes? Studies have shown that pilot error contributes to two-thirds of all such crashes. To address this problem, the airlines have upgraded their training programs by increasing the hours of classroom instruction and emphasizing communication skills in the cockpit. But it is unrealistic to expect such measures to compensate for pilots’lack of actual flying time. Therefore, the airlines should rethink their training approach to reducing commercial crashes.
Which one of the following is an assumption upon which the argument depends?
(A) Training programs can eliminate pilot errors.
(B) Commercial pilots routinely undergo additional training throughout their careers.
(C) The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time.
(D) Lack of actual flying time is an important contributor to pilot error in commercial plane crashes.
(E) Communication skills are not important to pilot training programs.
这题我是这样理解的:
原文说:公司进行课堂训练,但不能弥补实际训练,所要重新考虑
但课堂训练是不是重要,文章没提,也许是两个都重要,缺一不可的情况,所以c,e不对。
当然,作为加强,C、E都可,不过加强与假设不同啊
