16. In their native habit, amaryllis plants go dormant when the soil in which they are growing dries out during the dry season. Therefore, if amaryllis plants kept as houseplants are to thrive, water should be withheld from them during part of the year so that the plants go dormant.

Which one of the following is an assumption on which the argument depends?

(A) Most kinds of plants go dormant at some time or other during the year.

(B) Amaryllis are more difficult keep as houseplants than other kinds of plants are.

(C) Water should be withheld from amaryllis plants kept as houseplants during the exact time of year that corresponds to the dry season in their native habitat

(D) Any amaryllis plant that fails to thrive is likely to have been dormant for too short a time.

(E) Going dormant benefits amaryllis plants in their native habitat in some way other than simply preventing death during overly dry periods.
答案： E， 我选C，我认为C就是个bridge 联结论据与结论。
21. Claim: Country X's government lowered tariff barriers because doing so served the interests of powerful foreign companies.

Principle: In order for a change to be explained by the advantage some person or group gained from it, it must be shown how the interests of the person or group played a role in bringing about the change.

Which one of the following, if true, can most logically serve as a premise for an argument that uses the principle to counter the claim?

(A) Foreign companies did benefit when Country X lowered tariff barriers, but consumers in Country X benefited just as much.

(B) In the period since tariff barriers were lowered, price competition among importers has severely limited importers' profits from selling foreign companies' products in Country X.

(C) It was impossible to predict how Country X's economic reforms, which included lowering tariff barriers, would affect the economy in the short term.

(D) Many of the foreign companies that benefited from Country X's lowering tariff barriers compete fiercely among themselves both in Country X and in other markets.

(E) Although foreign companies benefited when Country X lowered tariff barriers, there is no other evidence that these foreign companies induced the change.

答案：E， 我选B
B：否定外国公司获利，正好与claimer相反。
谢谢！

16. 方法,结论: 干燥===>thrive E: dormant 有利(于茂盛), 而不是仅仅为了生存. 强调方法有效. C好像是个结论. 这题能看懂意思很重要.

21. E正确不用说了.
Principle: In order for a change to be explained by the advantage (some person or group gained from it), it must be shown how the interests of (the person or group) played a role in bringing about the change.

其中 some person or group gained from it 应该指 powerful foreign companies
其中 the person or group 也应该指 powerful foreign companies

大概意思就是A得到利益,A还要起作用. 问题要求用principle来做前提来反对.

B: 里面importers 有问题, 不如E 天衣无缝.

21， 是我看漏了题意，我只看到某团体获利，没看到在其中起作用，而且此题的重点还是在起作用。如果是这样，答案就是E。E很明确。有时做题经常会把题意看漏掉。不知有什么办法没有？

16， 是不是应该这样理解：

干燥=》go dormant ===>thrive 你的推理过程少了go dormant

E: dormant 有利(于茂盛), 而不是仅仅为了生存，强调方法的有效性。这就对了！！
E又提到了in their native habitat ，会不会有干扰，如果没有in their native habitat ，就是讲A植物的普遍性不是更好？

谢谢！！
