3. 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. Thus as
the population ages, companies producing carpet
will be able to gain market share in the carpet market
only through purchasing competitors, and not
through more aggressive marketing.
Which one of the following, if true, casts the most
doubt on the conclusion above?
--BIBLE WEAKEN NO.3
(A) Most of the major carpet producers market
other floor coverings as well.
(B) Most established carpet producers market
several different brand names and varieties,
and there is no remaining niche in the
market for new brands to fill.
(C) Two of the three mergers in the industry’s last
ten years led to a decline in profits and
revenues for the newly merged companies.
(D) Price reductions, achieved by cost-cutting in
production, by some of the dominant firms
in the carpet market are causing other
producers to leave the market altogether.
(E) The carpet market is unlike most markets in
that consumers are becoming increasingly
resistant to new patterns and styles.

2.
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

(A) Some areas of ocean in the Southern Hemisphere do not contain sufficient nutrients to support large seaweed farms.
(B) When a seaweed plant is burned, it releases an amount of carbon dioxide comparable to the amount it has absorbed in its lifetime.
(C) Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel.
(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.
(E) Seaweed farms would make more money by farming seaweed to sell as nutritional supplements than by farming seaweed to sell as fuel.

3.
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?
-- PREP07 CR1 NO.10
(A) In 1994 Videorama rented out more videos than it sold.
(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.

4.
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
(A) Gold is the background color on the label of many of the wines produced by Danville Winery.
(B) When the bottles are viewed side by side, Danville Winery's bottle is perceptibly taller than Mourdet Winery's.
(C) Danville Winery, unlike Mourdet Winery, displays its wine's label prominently in advertisements.
(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.
(E) Many popular wines are sold in bottles of a standard design.

5.
Finding of a survey of Systems magazine subscribers: Thirty percent of all merchandise orders placed by subscribers in response to advertisements in the magazine last year were placed by subscribers under age thirty-five.

Finding of a survey of advertisers in Systems magazine: Most of the merchandise orders placed in response to advertisements in Systems last year were placed by people under age thirty-five.

For both of the findings to be accurate, which of the following must be true?
-- PREP07 CR1 NO.12
(A) More subscribers to Systems who have never ordered merchandise in response to advertisements in the magazine are age thirty-five or over than are under age thirty-five.
(B) Among subscribers to Systems, the proportion who are under age thirty-five was considerably lower last year than it is now.
(C) Most merchandise orders placed in response to advertisements in Systems last year were placed by Systems subscribers over age thirty-five.
(D) Last year, the average dollar amount of merchandise orders placed was less for subscribers under age thirty-five than for those age thirty-five or over.
(E) Last year many people who placed orders for merchandise in response to advertisements in Systems were not subscribers to the magazine.

【精练题解释】
This is another difficult problem but very typical of the LSAT. As always, the
key to success is to isolate the conclusion, which appears in the last sentence:
“companies producing carpet will be able to gain market share in the carpet
market only through purchasing competitors.” As you should have noted while
reading, the conclusion contains a conditional indicator and is thereby
conditional in nature. The conclusion can be diagrammed as:
GMS = gain market share in the carpet market
C = purchasing competitors
GMS --->C
According to the author, to gain market share in the carpet market a company
must purchase a competitor. Answer choice (C) is often selected by students,
but it does not attack this idea. To attack a conditional statement you must show
that the necessary condition is not actually necessary for the sufficient condition
to occur. Answer choice (C) simply suggests that when companies purchase
their competitors the endeavor is often financially unsuccessful. Essentially,
answer choice (C) fails to prove that purchasing competitors is unnecessary to
gain market share. Answer choice (D), on the other hand, does suggest a way
for companies to gain market share without purchasing competitors, thereby
attacking the conditional statement given in the stimulus. Thus, answer choice
(D) is correct.
Answer choice (A): This answer goes beyond the scope of the argument, which
is limited to the carpet market (and not other floor coverings).
Answer choice (B): This is an Opposite answer that strengthens the argument.
If there are no remaining niches to fill, then there is no way to expand other than
to purchase a competitor.
Answer choice (C): This attractive answer is wrong for two very strong
reasons:
1. A Shell Game is played with the details of the conclusion. The
conclusion is about market share. Answer choice (C) is about a
decline in profits and revenues. The two are not the same, and so the
information in the answer choice does not weaken the conclusion.
2. Even if you assume that market share is the same thing as profits and
revenues, a second Shell Game is played because the answer then
attacks a conclusion that is similar but different than the given
conclusion.
If the conclusion were as follows:
C ---> GMS
then answer choice (C) would be correct (again, assuming market
share is the same thing as profits and revenues). But, the above is a
Mistaken Reversal of the conclusion, and so the attack is made on a
statement that uses the same terms as the conclusion but puts them in
a different relationship. This is a great example of the cleverness
displayed by the test makers. Fortunately you can avoid this answer if
you know what to look for when attacking conditional reasoning.
More on this topic in the next section.
One point worth noting is that it is no accident that the most tempting wrong
answer choice appears just before the correct answer. This is a classic LSAT
trick, and one that is very effective because most test takers relax once they find
an answer they feel is attractive. This makes them less likely to closely examine
the answers that follow. Never relax during the LSAT!
Answer choice (D): This is the correct answer. If price reductions drive out
some of the carpet producers, then other producers can take the market share
left behind. This scenario shows that a company can gain market share without
purchasing a competitor, thus attacking the necessary condition in the
conclusion.
Answer choice (E): This Opposite answer strengthens the argument. If the
consumers are resistant to new styles, then one fewer possibility exists if a
company is trying to increase market share. By eliminating this option, the
conclusion is strengthened (if you eliminate an idea that would hurt the
argument, that strengthens the argument because it has fewer “competitors.”
More on this later).

P: The consumers only change their carpets in their 20s/30s and 40s/50s.
C: The carpet company can only gain market share from purchasing its competitors, yet not from the carpet market growth.
Prephrase:
The carpet company's competitor have the price as same as this carpet company.
The exportation of carpet can induce more profit for the carpet company.
The promotion plan of the carpet company can be achieved by replacing old carpet with the new ones in a cheaper price.
Analysis:
(A) Most of the major carpet producers market
other floor coverings as well.
----------------------------------------------------------we don't care if the producer market other floor covering or not, since this is not the main point of the passage.
(B) Most established carpet producers market
several different brand names and varieties,
and there is no remaining niche in the
market for new brands to fill.
----------------------------------------------------------new brand names and varieties cannot conclude the carpet company can gain market share through purchasing competitors.
(C) Two of the three mergers in the industry’s last
ten years led to a decline in profits and
revenues for the newly merged companies.
-----------------------------------------------------------this is one example, but it cannot represent for the whole.
(D) Price reductions, achieved by cost-cutting in
production, by some of the dominant firms
in the carpet market are causing other
producers to leave the market altogether.
-----------------------------------------------------------contender.
(E) The carpet market is unlike most markets in
that consumers are becoming increasingly
resistant to new patterns and styles.
------------------------------------------------------------new patterns and styles are irrelevant,this is to support the conclusion.

分析不足：
reasons:
1. A Shell Game is played with the details of the conclusion. The
conclusion is about market share. Answer choice (C) is about a
decline in profits and revenues. The two are not the same, and so the
information in the answer choice does not weaken the conclusion.
对C的理解稍微还不够深刻，其实是shell game，C不能说明market share的增加是由于purchasing competitors引起的，所以即便是profit/revenue下降等等，都不够充分说明weaken的效果。

其次，对于D为什么是对的理解也不到位，用了POE方法排出，但是不能体会精髓！
Answer choice (D): This is the correct answer. If price reductions drive out
some of the carpet producers, then other producers can take the market share
left behind. This scenario shows that a company can gain market share without
purchasing a competitor, thus attacking the necessary condition in the
conclusion.

问题？？？
但是highlight部分我还是没太看明白，D到底是怎么证明carpet company can gain market share without purchasing a competitor的？要我看，最多证明carpet company是不能从purchasing competior 身上获利而已阿~~求解！

background: There is relatively little room for growth in the overall carpet market, which is tied to the size of the population.
premise: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.
conclusion:
Thus as the population ages, companies producing carpet will be able to gain market share in the carpet market only through purchasing competitors, and not through more aggressive marketing.

整体：
20、30 岁买一次，50、60岁买一次 ——》gain market share in the carpet market only through purchasing competitors, and not through more aggressive marketing.

pre：每年不都是有新一批的人长大2、30岁，5、60岁么？（请问我的pre跟答案一点关系都没有，大家都是怎么pre的啊？谢谢）

选了：d (是那种看了答案觉得应该是d)

选项分析：
a：market other floor covering as well 与 through 什么来gain market share无关
b：market several brands 也不会对gain market share产生影响，因为它是受人口限制的，人们只是在2、30和5、60岁的时候买一次。。。
c：mergers 三个中的两个导致newly merger利润和收入下降与gain market share无关。
d：主要的firm通过cut price让一些厂家离开了。。这是gain market 的另一手段。weaken了结论
e：消费者对新pattern的抵制，但是还是在2、30和5、60岁的时候买一次。。。对结论gain market share没有什么影响。。。

2、
目的：to remove excess carbon dioxide from the atmosphere
方法：to establish giant floating seaweed farms in the oceans. When the seaweed plants die, they will be disposed of by being burned for fuel.

pre：seaweed被burn了以后产生的carbon dioxide肿么办呢

a：在一定程度上不能贯彻plan的实施，削弱，没有b强
b：最削弱
c：some people在plan中不起作用，起作用了也是削弱plan的实施，但没有b强
d：范围太大，且跟plan无关
e：对题目所给条件的驳斥，题目已经说了they will be disposed of by being burned for fuel.而且即使这样的话，也是利于plan的实施，是增强。。

4、
p：Danville uses a similar bottle. Thus, it is likely that many customers intending to buy our wine will mistakenly buy theirs instead.
c：The two bottles can be readily distinguished: the label on ours, but not on theirs, is gold colored.

pre：关于区分bottle的方法影响消费者的决定

a：更加显示出两者区别，增加
b：同上
c：同上
d：影响消费者决定的因素与dw的说法不一致，削弱
e：无关

1/36’’ D
Background: because the size of population, the room left for the growth of carpet market is so little. Most people only buy carpet only once or twice through their life.
Premise: in order to gain market, the carpet companies only need to buy the competitors, not through the aggressive marketing.
Prephrase: what if the consumers are tired of the tedious styles, and turn to the foreign carpet manufacturer?
A: whether most of the major carpet producers market other floor coverings is irrelevant to the argument.
B: if there is no room for the new brands, it makes sense that purchasing competitors to gain market share, and to market aggressively is not that necessary. This supports the argument, not weakens it.
C: if only the newly merged companies suffered loss of revenue, while the companies merged for year kept benefit, the strategy of purchasing competitors works, then ,the argument is supported.
D: as many companies faded out from the carpet market, the market will be rearranged, the market will be divided by the dominant firms, there is no need to buy the competitors. The argument is weakened.
E: if the consumers are only interested in the old patterns and styles, then the only way to gain market share is to purchase competitors. The argument is supported.
2/39’’ B
Background: scientists are trying to remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life.
Premise: one proposition is to found immense floating seaweed farms in the oceans, and burn them for fuel when they die.
Prephrase: during their growth, the carbon dioxide is also let out, when they are burned, the large amount of carbon dioxide will comes out.
A: the atmosphere is a whole body, and incapability will be compensated by the farms in other ocean areas, so it is not the weakness of the plan.
B: this outcome signifies that the plan does nothing change to the total amount of carbon dioxide in the atmosphere.
C: the point is the carbon dioxide, not whether the fuel will be accepted.
D: this is irrelevant to the excess carbon dioxide in the atmosphere.
E: this does not support or weaken the plan.
3/59’’ E
Background: the number of rented videos in 1994 is 10000 fewer than that in 1993.
Premise: J said the decline was due to the opening of Videorama, which only provided video rental, but also sold video. B said as Videorama only sold 4000 videos, there must be other explanation to the decline.
Prephrase: the sold videos are lent to other people by the consumer, this make the number of people renting videos declines.
A: it is paradox to J’s argument.
B: this is the other explaination.
C: it will promote the video rental, not consistent with the fact.
D: it is personal habit, irrelevant to the argument.
E: many people are able to borrow videos from their friends, then less people will rent video from the shop.
4/50’’ D
Background: D’s new wine was introduced to compete with the most popular wine of another company. Their bottles are alike.
Premise: M thinks that customers will mistakenly buy the competitor’s wine. D thinks that the gold colored label on the bottles will make their wine distinguished by the customers.

关于逻辑链的第三题(video rental)有问题想请教一下,Brad的话中说videorama只sell了400,而其他的outlets确损失了10000,所以这个损失不能说是因为videorama的开张造成的。

题目是让weaken Brad的观点,我一开始是觉得如果如果Videorama租出的比卖出的多,那就能弥补这个当中购得差额了,所以一开始选了A。后来看了大家的解释后觉得E确实是一个更佳的答案。

那我想请问A为什么是错的呢？是因为它说借出的更多，到底多多少，是不是不够充分？还是说因为它没有针对题干中Brad的话提出质疑（题干只是说了卖掉的和减少的，并没有设计租出的量）呢？

可能问的比较罗嗦，呵呵，不好意思，希望能够得到回答，谢谢咯

Conclusion: companies should through purchasing competitors to gain market share, not through more aggressive marketing.
3. what if there are less companies.
4. C
A, 我觉得是无关选项。题目问的是gain market share in the carpet market.
B, 这个选项其实应该是支持文中结论吧。因为市场是小的，那么只能通过并购来提高市场占有量。哦，这个只是说明一个事实。并没有说他不成功的原因/
C，说明的一个事实，就75%的合并都是不成功的。应该是这个吧。
D，这个应该也是支持，说明merger不是唯一的方法。应该选这个的！
E，无关选项吧。

2. scientists want to remove EXCESS carbon dioxide by increasing the amount that is absorbed plants. and this plan is establish giant floating seaweed, after the seaweeds die, they will be disposed of by being burned for fuel.
3. what if those seaweed will absorbed more than excess carbon dioxide? What if the seaweed will product more carbon dioxide after they die?
4. B
A, 无关选项。题目并没有问实行这个计划的可行性。而是问如果这个计划可以实施，会产生什么样的不好处。
B，如果这种seaweeds 死后会产生更多CD的话，那么这个计划就是徒劳无功的。
C，无关选项，这已经是之后要考虑的问题。
D，这是提供一个事实，证明CD太多了，植物吸收不来。
E，题目并没有问道cost的问题。所以应该也是无关。

4. E
A, 这应该是一个track的选项，可是B对比的是V卖出去的和C失去的租界订单，所以V租出去的应该是没有关系的。
B，题中并没有提到，无关选项。
C，无关
D，无关
E，说的多好呀，还不准我买了之后借给我朋友啦。

4. D
A, 无关选项。DW的label的颜色没有什么可考察性。
B，这个是支持DW的说法的。

Jennifer: Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993.

BG：carpet marketing is limited.It is relative to the population.
Premise:people only use carpet when they are fifty to sixty years old or at certain young age.
Conclusion: carpet corporations must purchase their competitors to overcome the difficulty.
If it is not necessary to purchase competitors then the argument will be attacked.
choice

A irrelevant information,the focus is carpet market,not another floor covering.
B strenghten the plan
C strenghten the plan,cause the profits and revenue have already shrinked.
D weaken the plan,corporations don't have to merge eachother,the best corporation will stay and control the market by forcing other corporations to leave through price reduction.
E strenghten the plan
本题的启示：
1.无关的选项通常都是谈到一个相关的话题，但并非是结论中的中心。抓住结论的关键词（topic）无关的选项就会被排除，本题的无关选项是A。
2.shell game（小把戏，抑或叫诡辩）的识别：通常这种把戏会针对结论中的细节下手，本题C项是将结论中的topic：gain market share 换成了 increase profits and revenues。另一种可能是这种诡辩会对推理的方向下手，本题C项就是将推理方向调换，如果并购，那么利润会上升。而结论中需要反驳的推理是如何证明gain market share--->purchase competitors 是错的。这在逻辑上将其实就是逆命题和命题的真假并不总是同步的。
原题如下：供参考之用
3. 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. Thus as
the population ages, companies producing carpet
will be able to gain market share in the carpet market
only through purchasing competitors, and not
through more aggressive marketing.
Which one of the following, if true, casts the most
doubt on the conclusion above?
--BIBLE WEAKEN NO.3
(A) Most of the major carpet producers market
other floor coverings as well.
(B) Most established carpet producers market
several different brand names and varieties,
and there is no remaining niche in the
market for new brands to fill.
(C) Two of the three mergers in the industry’s last
ten years led to a decline in profits and
revenues for the newly merged companies.
(D) Price reductions, achieved by cost-cutting in
production, by some of the dominant firms
in the carpet market are causing other
producers to leave the market altogether.
(E) The carpet market is unlike most markets in
that consumers are becoming increasingly
resistant to new patterns and styles.

If the seaweed is burned and producing carbon dioxide again,the plan fails.

D irrelevant information,it has nothing to do with the way or the stimulus to buy videos.The key problem is why selling videos lead to the rental decline.
E correct.because selling videos will broadly decline the the number of potential customers who want to see videos.
本题启示：错选无关信息的选项常常是因为造成了错误的遐想。
克服错误的遐想的方式是：明确谈论对象，将对象间的逻辑简化。本题逻辑：反驳光碟卖出数量的上升无法填补出租数量下降。因此，辩论关键是证明光碟卖出数量是可以弥补出租数量下降的。

C: The decline in rentals was probably due almost entirely to the February 1994 opening of Videorama

: 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

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

Background: There's little room of carpet market, which is tied to the size of population. People only buy carpet once or twice in their whole lief.
Premise: As people get old.
Conclusion: Carpet company will get more profit only through purchasing competitor (?), not aggressive marketing.
Prephrase:
As the first purchased customers getting old, there'll also be some new customers growing to the age of 20s or 30s. - Aggressive marketing will still work.
Marketing overseas in a new market?
(WRONG GUESS)
Didn't understand the key point of this question: market share.
Answers:
(A) "floor covering" is IRRELEVANT
(B) "no remaining niche for a new brand" ~~IRRELEVANT~~ - SUPPORT
This is an Opposite answer that strengthens the argument.
If there are no remaining niches to fill, then there is no way to expand other than
to purchase a competitor.
(C) ~~"2/3 emerged companies declined in profit" explain the market is hard to get in, but doesn't doubt the conclusion.~~ (Didn't understand Answer-C: MERGER-NOT imerge)
Answer choice (C) simply suggests that when companies purchase
their competitors the endeavor is often financially unsuccessful. Essentially,
answer choice (C) fails to prove that purchasing competitors is unnecessary to
gain market share.
(D) CORRECT
~~"the dominant company cut price through lower cost so that others leave the market" doesn't doubt the conclusion.~~
* Cutting down the cost -> Lower prices -> Competitors leaving -> Bigger market share

3. 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. Thus as
the population ages, companies producing carpet
will be able to gain market share in the carpet market
only through purchasing competitors, and not
through more aggressive marketing.
Which one of the following, if true, casts the most
doubt on the conclusion above?
(A) Most of the major carpet producers market
other floor coverings as well.
Whether the producers market other products has no bearing on the carpet market.

(B) Most established carpet producers market
several different brand names and varieties,
and there is no remaining niche in the
market for new brands to fill.
The truth doesn’t weaken the conclusion got by the author; no remaining niche market can leads to both merging and fierce competition.

(C) Two of the three mergers in the industry’s last
ten years led to a decline in profits and
revenues for the newly merged companies.
The author’s conclusion focus on the market share got by merging rather than revenues.

(D) Price reductions, achieved by cost-cutting in
production, by some of the dominant firms
in the carpet market are causing other
producers to leave the market altogether.
This truth weakens the author’s conclusion soundly; since price competition leads to some companies’ failure, the author’s claim that companies cannot gain market share through aggressive market is invalid.

(E) The carpet market is unlike most markets in
that consumers are becoming increasingly
resistant to new patterns and styles.
Whether customers are resistant to new patterns and styles is irrelevant with the author’s conclusion.

逻辑链：
Truth 1: Growth room of carpet market is little.
Truth 2: The frequency of purchase is low, as the product is enduring.
Supposition: Companies will be only able to gain market share by merging competitors rather than by marketing more aggressively.
Weaken point: There are companies that failed in the market because of aggressive competition.

Aim: To remove excess carbon dioxide in air.
Proposed plan: To establish giant floating seaweed farms in the oceans. When they died, can be disposed of by being burned for fuel.
Weaken point: When they were burned, they release carbon dioxide as much as they absorb.

Truth: Video rental outlet was 10000 fewer in 1994 than that in 1993.
J said: For video rental shops also sell them cheaply.
B said: But the number sold is only 4000, while the number of declined rental is 10000.
Weaken B: People buy videos frequently borrow them to their friends.

Truth: DW’s new wine is similar in appearance with MW’s wine.
MW: Customers will mistake DW’s wine for MW’s wine.
DW: The label on ours is different from that of theirs.
Weaken DW: Customers purchase a bottle of wine on the basis of a general impression.

Finding 1: 30% of orders placed by subscribers in response to AD in the magazine last year were placed by subscribers under 35.
Finding 2: Most of orders placed in response to AD in the magazine last year were placed by people under 35.
Support point: Most subscribers under 35 place orders in response to AD in the magazine are not subscribers of the magazine.

(C) Two of the three mergers in the industry’s last
ten years led to a decline in profits and
revenues for the newly merged companies.

It tells that merging perhaps is bad. However, we should notice that the phenomenon is not sufficient to represent the whole situation.
(D) Price reductions, achieved by cost-cutting in
production, by some of the dominant firms
in the carpet market are causing other
producers to leave the market altogether.

It strengthens the conclusion that the carpet market needs merging, rather than more aggressive marketing.

It reveals that if firms find ways to cut cost in production, they will benefit from the action, causing other producers to leave the market altogether.
(E) The carpet market is unlike most markets in
that consumers are becoming increasingly
resistant to new patterns and styles.

If ‘in that’ is referred to most markets, the answer means that the consumers in the carpet market tend to like more aggressive markets, rather than merging. So it is the best answer.

It means that the consumers in the carpet market are becoming increasingly resistant to new patterns and styles. So we need no more aggressive marketing. It strengthens the consluion.

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

(A) Some areas of ocean in the Southern Hemisphere do not contain sufficient nutrients to support large seaweed farms.

Although the argument seems to weaken the plan, the phenomenon is unrepresentative to reveal the whole condition, considering that other areas of ocean may contain sufficient nutrients.
(B) When a seaweed plant is burned, it releases an amount of carbon dioxide comparable to the amount it has absorbed in its lifetime.

The purpose of the plan is to remove excess carbon dioxide. If the amount of carbon dioxide cannot be reduced through the plan, there is no reason to advocate the plan. So it weakens the argument.
(C) Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel.

We need not consider that whether some people would be reluctant to conduct the plan.
(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.

It seems to relate with the first sentence in the argument, but it cannot decide the availability of the plan, because the argument talks about the ‘excess carbon dioxide’.
(E) Seaweed farms would make more money by farming seaweed to sell as nutritional supplements than by farming seaweed to sell as fuel.
There is no relationship with money.

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?
-- PREP07 CR1 NO.10

(A)In 1994 Videorama rented out more videos than it sold.

Videorama is unrepresentative to the video rental outlets in Centerville. Besides, the condition in Videorama is opposite to the whole trend.
(B) In 1994 two new outlets that rent but that do not sell videos opened in Centerville.

The two new outlets cannot help us to understand more about the real reason of the decline.
(C) Most of the video rental outlets in Centerville rent videos at a discount on certain nights of the week.

If the fact is true, the revenue in rentals should rise, because the discount stimulates the demand.
(D) People often buy videos of movies that they have previously seen in a theater.

If the fact is true, the revenue in rentals should rise.
(E) People who own videos frequently loan them to their friends.

It most seriously weakens the objection provided by Brad, because if the people who own videos frequently loan them to other people, even 4,000 is smaller than 10,000, people who need to rent videos from rental outlets can just borrow them from their friends, thus weakening the objection.

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

(A) Gold is the background color on the label of many of the wines produced by Danville Winery.

It cannot weaken Danville Winery’s response.
(B) When the bottles are viewed side by side, Danville Winery's bottle is perceptibly taller than Mourdet Winery's.

It strengthens DW’s response, since we can see the distinction between them.
(C) Danville Winery, unlike Mourdet Winery, displays its wine's label prominently in advertisements.

It cannot weaken DW’s response, because displaying label prominently in advertisements has no relationship with similarity of the bottle.
(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.

Since consumers will have the most impression with the bottle, it weakens DW’s response. So it is the best answer.
(E) Many popular wines are sold in bottles of a standard design.
It weakens MW’s reason, rather than DW’s response.

Finding of a survey of Systems magazine subscribers: Thirty percent of all merchandise orders placed by subscribers in response to advertisements in the magazine last year were placed by subscribers under age thirty-five.

Finding of a survey of advertisers in Systems magazine: Most of the merchandise orders placed in response to advertisements in Systems last year were placed by people under age thirty-five.

For both of the findings to be accurate, which of the following must be true?
-- PREP07 CR1 NO.12

(A) More subscribers to Systems who have never ordered merchandise in response to advertisements in the magazine are age thirty-five or over than are under age thirty-five.

We know nothing about subscribers thirty-five or older.
(B) Among subscribers to Systems, the proportion who are under age thirty-five was considerably lower last year than it is now.

There is no comparison with subscribers between last year and this year.
(C) Most merchandise orders placed in response to advertisements in Systems last year were placed by Systems subscribers over age thirty-five.

The second sentence tells us that most merchandise orders were placed by people under age 35.
(D) Last year, the average dollar amount of merchandise orders placed was less for subscribers under age thirty-five than for those age thirty-five or over.

We know nothing about the average dollar amount of merchandise orders.
(E) Last year many people who placed orders for merchandise in response to advertisements in Systems were not subscribers to the magazine.

It seems to irrelevant to the argument, but if you consider more deeply, you’ll find that it is the best answer. Because 30% of the orders placed by subscribers were under 35, and most of the orders placed by people were under 35, there are more people who placed the orders were not subscribers.
