Although fullerenes -- spherical molecules made entirely of carbon--were first found in the laboratory, they have since been found in nature, formed in fissures of the rare mineral shungite.Since laboratory synthesis of fullerenes requires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's crust at the time these naturally occurring fullerenes were formed.

Which of the following, if true, most seriously undermines the argument?

(A) Confirming that the shungite genuinely contained fullerenes took careful experimentation.

(B) Some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft.

(C) The mineral shungite itself contains large amounts of carbon, from which the fullerenes apparently formed.

(D) The naturally occurring fullerenes are arranged in a previously unknown crystalline structure.

(E) Shungite itself is formed only under distinctive conditions.

Tiger sharks are common in the waters surrounding Tenare Island.Usually tiger sharks feed on smaller sharks, but sometimes they have attacked tourists swimming and surfing at Tenare's beaches.This has hurt Tenare's tourism industry, which is second only to its fishing industry in annual revenues.In order to help the economy, therefore, the mayor of the island has proposed an ongoing program to kill any tiger sharks within a mile of the beaches.

Which of the following, if true, most strongly calls into question the likelihood that implementation of the mayor's proposal will have the desired consequence?

(A) Even if not all the tiger sharks that come close to the beaches are killed, the existence of the program would reassure tourists.

(B) Business owners who depend on tourism are willing to pay most of the cost of implementing the program.

(C) Tourists come to Tenare Island for its beaches, even though the island features a number of other tourist attractions.

(D) The small sharks on which tiger sharks prey feed on fish that are commercially important to the island's fisheries.

(E) Not all tourists who come to Tenare Island enjoy swimming or surfing.

Jennifer:Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993.The decline in rentals was probably due almost entirely to the February 1994 opening of Videorama, the first and only video rental outlet in the area that, in addition to renting videos, also sold them cheaply.

Brad:There must be another explanation:as you yourself said, the decline was on the order of 10,000 rentals.Yet Videorama sold only 4,000 videos in 1994.

Which of the following, if true, would most seriously weaken the force of the objection that Brad presents to Jennifer's explanation?

(A) In 1994 Videorama rented out more videos than it sold.
（为什么不是A选项呢？）

(B) In 1994 two new outlets that rent but that do not sell videos opened in Centerville.

(C) Most of the video rental outlets in Centerville rent videos at a discount on certain nights of the week.

(D) People often buy videos of movies that they have previously seen in a theater.

(E) People who own videos frequently loan them to their friends.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.

Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?

(A) When a prey insect is moved directly toward a beetle that has been chasing it, the beetle immediately turns and runs away without its usual intermittent stopping.

(B) In pursuing a moving insect, the beetles usually respond immediately to changes in the insect's direction, and pause equally frequently whether the chase is up or down an incline. （B选错在哪里啊？）

(C) The beetles maintain a fixed time interval between pauses, although when an insect that had been stationary begins to flee, the beetle increases its speed after its next pause.

(D) If, when a beetle pauses, it has not gained on the insect it is pursuing, the beetle generally ends its pursuit.

(E) When an obstacle is suddenly introduced just in front of running beetles, the beetles sometimes stop immediately, but they never respond by running around the barrier.

原文暗示的意思是，如果实验室里的分子结构富勒烯球产生于高温高压的环境，那么如果在自然环境里面发现富勒烯的话，说明自然环境也是高温高压。抽象来看，就是说发现同样的结果，也能推知同样的原因。如果要undermine这个结论，那么不看答案的时候有几个可能性：首先结果不必然来自于原因，第一，富勒烯不是地球自产的，第二，实验没有考虑到其他制造富勒烯的可能性。其次，结果本质上不同，两种富勒烯实际上不一样。
中间提到了一种矿物质，实际上，它是与富勒烯同等地位的，是原因和结果之间的媒介，因为原文没说他们是同时产生的。
答案，A错，因为只是陈述了原因和结果之间的联系。
B错，这个有点意思，但是不对，因为用了some，实际上是肯定了原文结论，因为表明至少有一部分富勒烯是地球自产。
C错，同A
D对，说明结果本质上不同，两种富勒烯不一样。
E错，富勒烯不一定与Shungite同时产生

这道题三个细节是关键，第一，虎鲨吃鲨鱼，第二，旅游业排在渔业后面，第三，只灭虎鲨。结论是灭虎鲨拯救旅游业。要put in question, 不看答案猜测有以下可能，灭虎鲨对旅游业好，但是其他鲨鱼吃人，削弱旅游业。灭虎鲨，其他鲨鱼增加（这个其实是暗含的必然结果），鲨鱼吃鱼，削弱渔业，因为旅游业在渔业后面，所以两者作用抵消，或者净损失。还有，虎鲨本身是旅游观光的目的。
答案，A错，加强结论
B错，加强结论
C错，无关选项，但是其实也加强结论，因为爱beach，不下水，就不怕虎鲨
D对，解释同上面所述
E错，同C

小J说，C的出租video的店94年出租数量大幅下降10000是几乎全因为V新开了一家又租又卖的点
小B说，不对，因为他们只卖了4000张盘，不足以解释少租10000。
要灭B的说法，也就是支持J。
怎么灭B呢？就是说要用卖的4000能解释10000。
答案， A错，就算V租的多了，实际上并没有大力削弱B的反驳，只是支持了J的说法，因为B主要说，卖的少不会导致租的大幅下降。比较E来说，E正是说，少量卖实际上抑制了需求，从而降低了C的出租量。这个选项好于A。

看完题目，实际上对于虎甲虫捕食行动有两种解释，一个是腿的问题，一个是脑子问题，不看选项，正确答案应该是支持一个灭另一个。就看看哪个只对腿，哪个只对脑子。
A错，因为根本没有提到中间休息问题。
B错，因为实际上这句话是对于甲虫捕食行为的一个例子，原文是，甲虫开始追，中间休息下，然后接着追，这个选项也是，发现猎物，开始追，中间等频率休息，然后接着追。这个中间休息，还是可以用腿或者脑都能解释，可以等频率累了，腿休息会儿，也可能是大脑等频率过载。这个区别于正确选项C。
C对，甲虫等时间休息，就算加速追，也等时间休息，这说明，不是因为腿累了，而是脑子等时间就过载一次，因为加速追只影响腿，不影响脑子。
D错，也可以用腿和脑子都能解释，腿休息够了，或者脑子缓过来了，发现追不上，都可能不追了。
E错，甲虫吓傻了，和题目的捕食行为没关系
