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.
There is no relationship with other floor coverings.
(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.
It strengthens the conclusion, instead of weakening.
(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.
