Statistician: A financial magazine claimed that its
survey of its subscribers showed that North
Americans are more concerned about their
personal finances than about politics. One
question was: “Which do you think about
more: politics or the joy of earning money?”
This question is clearly biased. Also, the readers
of the magazine are a self-selecting sample.
Thus, there is reason to be skeptical about the
conclusion drawn in the magazine’s survey.
Each of the following, if true, would strengthen the
statistician’s argument EXCEPT:

逻辑链：C：the survey in this magazine is biased
R:the question and the sample is biased and non-represent
问weaken ：也就是说survey是公正的，说他biased从问题和样本出发，那么找一个可以改变这个的因素

(A) The credibility of the magazine has been called
into question on a number of occasions.——support
(B) The conclusions drawn in most magazine
surveys have eventually been disproved.——support
(C) Other surveys suggest that North Americans are
just as concerned about politics as they are
about finances.——support注意：just as 就是一样，跟原来杂志中的more不一样哦，不要搞混了
(D) There is reason to be skeptical about the results
of surveys that are biased and
unrepresentative.——support
(E) Other surveys suggest that North Americans are
concerned not only with politics and
finances, but also with social issues.——weaken！这算是正面评价咩！

Beta Corporation claims that it no longer has enough work for the 60 computer data-entry workers that it is laying off.  These workers have heard, however, that the company is buying 100 new computers.  So the workers concluded that the company's real reason for laying them off is to fill their jobs with lower-paid workers.
Which of the following, if true, would most undermine the workers' conclusion?
逻辑链：C：company lays works inorder to employs less paid worker
P:company has no more work,but it buys many new computers
问削弱:因果型结构，问削弱，就是其实不是为了找更便宜的工人，而且真的是没有更多的工作来做了。
那么为什么买电脑？有别的用途。用电脑代替人？选项会出现新电脑的用途。

(A)Most of the workers being laid off know how to enter data on a number of different computer systems.——irrelevant
(B) Orders for almost all of Beta Corporation products have increased over the past year.——irrelevant
(C) A recent memorandum from the president of Beta Corporation requested that all data generated by the company be stored in computerized form.——irrelevant，如果这样的话还要买电脑干嘛？
(D) Beta Corporation's computer data-entry workers are more experienced and hence more highly paid than people doing comparable work in other companies.——irrelevant
(E) Beta Corporation's new computers will allow its current management and sales staff to perform many of the tasks that the data-entry workers were previously doing.——bingo！解雇一部分人，让留下来的其他职位的人填补这个口子，分担工作。

Which of the following most logically completes the passage?
For the past several years, a certain technology has been widely used to transmit data among networked computers.  Recently two data transmission companies, Aptron and Gammatech, have each developed separate systems that allow network data transmission at rates ten times faster than the current technology allows.  Although the systems are similarly priced and are equally easy to use, Aptron's product is likely to dominate the market, because __________.
逻辑链：C: A’s product dominate the market than G’s
P: AandG have the same priced and easy to use
问原因：类比，出现一个A比G的优势的选项
(A) Gammatech has been in the business of designing data transmission systems for several years more than Aptron has——这是weaken，砸场子来的吧
(B) the number of small businesses that need computer networking systems is likely to double over the next few years——irrelevant
(C) it is much more likely that Gammatech's system will be expandable to meet future needs——weaken
(D) unlike many data transmission companies, Aptron and Gammatech develop computers in addition to data transmission systems——共同的，irrelevant
(E) it is easier for users of the current data transmission technology to switch to Aptron's product than to Gammatech's——bingo！switch easily！妈妈再也不用担心我的智商！

Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive.  Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600.  However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.
Which of the following is an assumption on which the argument depends?
逻辑链：C：RDS station up, radio (with RDS) stable
P: radio （with RDS）can receive the special program,only this kind can receive
问assumption：相关因果性，前提说了R和RDS相关联，后者一个在变化时候，一个不再变化，但是前提看来二者是有相关性的，问假设，其实就是问取非削弱的那个选项切断了相关性。选项必须提到因果
(A) Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.——irrelevant
(B) In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.——irrelevant，问的是R的数据变化
(C) Equipping a radio station with RDS technology does not decrease the station's listening area.——那么为什么RDS还在up呢？
(D) In 1996 Verdlanders who did not own radios equipped to receive RDS could not receive any programming from the RDS radio stations that began broadcasting in Verdland after 1994.——bingo!取非削弱了原题，切断了相关性
(E) The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.——跟两个变量无关

Situation:  For five years the Souper restaurant chain has maintained rapid sales growth in Danport, primarily by opening new restaurants that draw patrons away from other restaurants in their vicinity.
Goal:  Souper wishes to achieve continued rapid sales growth in Danport over the next two years.
Proposal for consideration:  Continue to open new restaurants in Danport during the next two years at the same rate as in the last two years.

P sales up,due to attract partrons from other restaurants.

(B) The Souper chain has generally opened new restaurants in locations that are in the vicinity of a large number of other restaurants.——support
(C) Souper restaurants generally offer a much smaller variety of foods than many of the other restaurants in their vicinity.——irrelevant
(D) Virtually all potential sites for new Souper restaurants in Danport are located in the vicinity of existing Souper restaurants.——bingo！相煎何太急！
(E) Souper restaurants have always offered meals that are somewhat less expensive than meals at restaurants that compete with Souper for patrons.——support
