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。。


3、1’13‘’
没有感觉?


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


5、
没有感觉


请问下大家:想第3、5题这种题目读完了没有任何感觉。也不知道思路是什么。。要肿么练习呢。。。谢谢

来做作业喽~~看这这么高的人气还是很开心的说哈~~吼吼~~~
1.【40s】【前提结论型】
P:the room of the market for the C Company to expand is hard-->people only buy twice C product in their whole life.-->the market share is tied to the population.
C:there is no way to improve the market share only through defeat other competitors.
weaken: there is a report that in the future the population age from 20-60 will more than the past.[find reason to support that the marking in fact is aggressive]
A:

A) Most of the major carpet producers market
other floor coverings as well.-->irrelevant with the floor
(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.--> irrelevant wit the new brands.【X-->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.-->support【market share<-->profits】
(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.-->support【R】
(E) The carpet market is unlike most markets in
that consumers are becoming increasingly
resistant to new patterns and styles.-->R【x--> support,连选项的意思都搞错了,泪奔啊。。。】
LSAT的逻辑真是做的有够重伤的,想起以前抓那个lsat的阅读的时候也是。。。。。
哎哎。。。总结下我这道题的错误点:
首先还是结论重心木有抓住,攻击点攻击错了,是要攻击通过并购这种方式并不是唯一的增加市场份额的选择,而不是攻击市场不够aggressive。。。哎。。想偏到十万八千里了。
C选项真的很阴险,还是要紧扣结论关系才能作对,就是方式:并购——》目的:扩大市场份额的关系。

(C) Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel.-->same as A.
