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.

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.

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.

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.

Key: D B E D E 答案在此处，把前面的选中就可以看到了~被设成白色的啦~

【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).

精练-------〉45s（第一遍没读懂）-----------weaken
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！

1.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: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.
maybe more aggressive marketing will attract consumers who originally want to buy carpets once~(这个理由不成立吧...)
(A) Most of the major carpet producers market other floor coverings as well.
--it's about the carpet market--irrelevant
(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.
--i don't know~maybe~irrelevant?--support
(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.
--not about competitors-,but still gain market shares-right
(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.
--competitors--support--right
(E) The carpet market is unlike most markets in that consumers are becoming increasingly resistant to new patterns and styles.

--it has nothing to do with the choice of consumers--irrelevant--support
