这个看了两分钟……不是全明白，一开始选的D，后来改的C……桑心
There is relatively little room for growth in theoverall carpet market, which is tied to the size of thepopulation. Most who purchase carpet do so onlyonce or twice, first in their twenties or thirties, andthen perhaps again in their fifties or sixties. Thus asthe population ages, companies producing carpetwill be able to gain market share in the carpet marketonly through purchasing competitors, and notthrough more aggressive marketing.Which one of the following, if true, casts the mostdoubt on the conclusion above?--BIBLE WEAKEN NO.3
逻辑链：因为人买的少，carpet市场小——扩大市场份额只能通过合并竞争对手而不是自己积极扩大市场份额
问削弱：通过自己的策略扩大市场份额

(A )Most of the major carpet producers marketother floor coverings as well.——无关吧，这个只是说了carpet producer出售的一个情况，无法削弱
(B) Most established carpet producers marketseveral different brand names and varieties,and there is no remaining niche in themarket for new brands to fill.——同A，无关
(C) Two of the three mergers in the industry’s lastten years led to a decline in profits andrevenues for the newly merged companies.——无关
(D) Price reductions, achieved by cost-cutting inproduction, by some of the dominant firmsin the carpet market are causing otherproducers to leave the market altogether.——bingo！学营销的居然一开始没看出来，这就是通过价格战略扩大市场份额
(E) The carpet market is unlike most markets inthat consumers are becoming increasinglyresistant to new patterns and styles.——无关

Scientists are discussing ways to remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life.  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.Which of the following, if true, would indicate the most serious weakness in the plan above?-- PREP07 CR1 NO.9
逻辑链：为了降低CD——所以在海上种S，S死后被焚烧
问削弱：目的是减少CD，只要找出S计划实施之后CD还是没有减少就可以
(A) Some areas of ocean in the Southern Hemisphere do not contain sufficient nutrients to support large seaweed farms.——跟CD减少无关啊
(B) When a seaweed plant is burned, it releases an amount of carbon dioxide comparable to the amount it has absorbed in its lifetime.——bingo!这样CD还是没有减少，计划失败
(C) Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel.——也不管CD什么事
(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.——还是算是减少了对吧，属于suppor
t(E) Seaweed farms would make more money by farming seaweed to sell as nutritional supplements than by farming seaweed to sell as fuel.——也跟CD减少无关

这个我也错了一开始，选的AJennifer:  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?-- PREP07 CR1 NO.10

逻辑链：女：C在1994年销量下降了10000,因为另一个能租能卖又便宜的V营业了
男：有其他原因，因为94年V只卖了4000个
问削弱男的
思路：没有其他原因，就是因为V开了，找到填补6000的法子（原谅我逻辑一直很紊乱）
(A) In 1994 Videorama rented out more videos than it sold.——因为其他原因，理论上还是support了男的观点
(B) In 1994 two new outlets that rent but that do not sell videos opened in Centerville.——support男的
(C) Most of the video rental outlets in Centerville rent videos at a discount on certain nights of the week.——无语，无关
(D) People often buy videos of movies that they have previously seen in a theater.——也无关
(E) People who own videos frequently loan them to their friends.——bingo！解释了那6000去哪了，因为有的人买了videos借给朋友，可以填补6000的空缺

Mourdet Winery:  Danville Winery's new wine was introduced to compete with our most popular wine, which is sold in a distinctive tall, black bottle.  Danville uses a similar bottle.  Thus, it is likely that many customers intending to buy our wine will mistakenly buy theirs instead.Danville Winery:  Not so.  The two bottles can be readily distinguished:  the label on ours, but not on theirs, is gold colored.
Which of the following, if true, most undermines Danville Winery's response?-- PREP07 CR1 NO.11

逻辑链：MW：有个新的DW酒跟我们最popular的酒包装一样，消费者可能误选
DW：不会，因为我们的标签是金色哦
问削弱DW的
思路：肯定会让消费者误选即使是标签是金色的，也许是消费者不会管你标签是金色还是红色，他们对这个不感冒，只看大方向
(A) Gold is the background color on the label of many of the wines produced by Danville Winery.——无关
(B) When the bottles are viewed side by side, Danville Winery's bottle is perceptibly taller than Mourdet Winery's.——也无关
(C) Danville Winery, unlike Mourdet Winery, displays its wine's label prominently in advertisements.——细思极恐。。。这个的可持续影响等于是支持了DW的了，这里不讨论
(D) It is common for occasional purchasers to buy a bottle of wine on the basis of a general impression of the most obvious feature of the bottle.——bingo！消费者的关注点不在label上
(E) Many popular wines are sold in bottles of a standard design.——无关

(B) When a seaweed plant is burned, it releases an amount of carbon dioxide comparable to the amount it has absorbed in its lifetime. 正解 削弱，吸收的都被释放出来了，没有任何作用
(C) Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel. 无关，跟new fuel无关吧，讨论的是这种plants吸收CD的功效，有效了 则plan起作用了
(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. 不能削弱，可以吸收则已经减少了CD 是起作用的
