Lsat set2-10 and 11

10.Advertisers are often criticized for their unscrupulous manipulation of people’s tastes and wants. There is evidence, however, that some advertisers are motivated by moral as well as financial considerations. A particular publication decided to change its image from being a family newspaper to concentrating on sex and violence, thus appealing to a different readership. Some advertisers withdrew their advertisements from the publication, and this must have been because they morally disapproved of publishing salacious material.
Which one of the following, if true, would most strengthen the argument?
(A) The advertisers switched their advertisements to other family newspapers.
(B) Some advertisers switched from family newspapers to advertise in the changed publication.
(C) The advertisers expected their product sales to increase if they stayed with the changed publication, but to decrease if they withdrew.
(D) People who generally read family newspapers are not likely to buy newspapers that concentrate on sex and violence.
(E) It was expected that the changed publication would appeal principally to those in a different income group.

这个问题的结论到底是什么?第一句还是第二句?答案C应该是支持第一句的.
11.11. “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.

我觉得答案是D,但却是B正确,为什么?

Q10, 结论是第二句,但最后一句加上C则正好可以加强结论。

Q11,我也选的D,我觉得B明显就是错的,是不是给的答案有误?

Q11,

biologist 的命题是: deforestation continues→the koala becomes extinct(A→B)

politician’s claim的命题:stop deforestation→save the koala .(-A→-B,B→A)

B选项:-A,B. 与b不矛盾,与p矛盾

D选项:-A,-B,与b、p都不矛盾。所以选B

非形式逻辑,仅供参考。
