P: There is relatively little room for growth in the overall carpet market, which is tied to the size of the population. Most who purchase carpet do so only once or twice, first in their twenties or thirties, and then perhaps again in their fifties or sixties.

(E) The carpet market is unlike most markets in that consumers are becoming increasingly resistant to new patterns and styles. ---support，对新款式抵抗，所以不应该营销

P: One plan to accomplish this is to establish giant floating seaweed farms in the oceans.  When the seaweed plants die, they will be disposed of by being burned for fuel.
C: Scientists are discussing ways to remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life.
Weaken: burn产生的CO2比植物吸收的更多
(A) Some areas of ocean in the Southern Hemisphere do not contain sufficient nutrients to support large seaweed farms. ---irrelevant
(B) When a seaweed plant is burned, it releases an amount of carbon dioxide comparable to the amount it has absorbed in its lifetime. ---correct, weaken, 这样种植物的效果就没有了
(C) Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel. ---somehow support
(D) Each year about seven billion tons of carbon dioxide are released into the atmosphere but only about five billion tons are absorbed by plant life. ---不能weaken通过植物减少CO2的结论，反而支持，因为确实减少了CO2的量
(E) Seaweed farms would make more money by farming seaweed to sell as nutritional supplements than by farming seaweed to sell as fuel. ---无关

Jennifer:  : Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993. the first and only video rental outlet in the area that, in addition to renting videos, also sold them cheaply.
C: The decline in rentals was probably due almost entirely to the February 1994 opening of Videorama
Brad:  : as you yourself said, the decline was on the order of 10,000 rentals.  Yet Videorama sold only 4,000 videos in 1994.
C: There must be another explanation
Weaken B: 另外6000是这4000个买的时候同时租出去的~
(A) In 1994 Videorama rented out more videos than it sold. ---support, correct，解释了另外6000也是V造成的
(B) In 1994 two new outlets that rent but that do not sell videos opened in Centerville. ---无关

(D) People often buy videos of movies that they have previously seen in a theater. ---out of scope
(E) People who own videos frequently loan them to their friends. ---support B
正确答案：E  因为A只说租出的比卖出的多，不能说明总共数量超过10000，所以不能支持entirely, 而且不能直接削弱Brad对于sold数量问题的怀疑…而E，买到之后借给朋友能够解释少了租出的部分，所以削弱Brad说的因为只卖出4000就不能归因于opening of Videorama。。。。
