1. The value of a product is determined by the ratio of its quality to its price. The higher the value of a product, the better will be its competitive position. Therefore, either increasing the quality or lowering the price of a given product will increase the likelihood that consumer will select that product rather than a competing one.
Which of the following, if true, would most strengthen the conclusion drawn above?
(A) It is possible to increase both the quality and the price of a product without changing its competitive position.
(B) For certain segments of the population of consumers, higher-priced brands of some product lines are preferred to the lower-priced brands.
(C) Competing products often try to appeal to different segments of the population of consumers.
(D) The competitive position of a product can be affected by such factors as advertising and brand loyalty.
(E) Consumers' perceptions of the quality of a product are based on the actual quality of the product.
为什么A不对,C是怎样加强的?
2. The excessive number of safety regulation that the federal government has placed on industry poses more serious hardships for big businesses than for small ones. Since large companies do everything on a more massive scale, they must alter more complex operations and spend much more money to meet governmental requirements.
Which of the following , if true, would most weaken the argument above?
(A) Small companies are less likely than large companies to have the capital reserves for improvements.
(B) The operation codes are uniform, established without reference to size of company.
(C) Safety regulation codes are uniform, established without reference to size of company.
(D) Large companies typically have more of their profits invested in other businesses than do small companies.

我觉得C比A更能削弱argument
3.The population of elephant seals,reduced by hunting to perhaps a few dozen animals early in this century,has soared under federal protection during the last few decades.However,because the species repopulated itself through extensive inbreeding,it now exhibits a genetic uniformity that is almost unparalleled in other species of mammals,and thus it is in far greater danger of becoming extinct than are most other species.
Given the information in the passage above,which of the following is most likely the reason that other species of mammals are less likely that elephant seals to become extint?
(A)Other species of mammals have large populations,so the loss of a few members of the species is not significant.
(B)Other species of mammals have increased their knowledge of dangers through the experience of generation after generation of animals.
(C)In other species of mammals,hunters can readily distinguish between males of between young animals and adults.
(D)In other species of mammals,some members of the species are genetically better equipped to withstand a disease or event that destroys other members of the species.
(E)Other species of mammals have retained habits of caution and alertness because they have not been protected as elephant species.
虽然用排除法选出D,但不太清楚the line of reasoning
17. Advertiser: The revenue that newspapers and magazines earn by publishing advertisements allows publishers to keep the prices per copy of their publications much lower than would otherwise be possible. Therefore, consumers benefit economically from advertising.
Consumer: But who pays for the advertising that pays for low-priced newspapers and magazines? We consumers do, because advertisers pass along advertising costs to us through the higher prices they charge for their products.
Which of the following best describes how the consumer counters the advertiser's argument?
(A) By alleging something that, if true, would weaken the plausibility of the advertiser's conclusion
(B) By questioning the truth of the purportedly factual statement on which the advertiser's conclusion is based
(C) By offering an interpretation of the advertiser's opening statement that, if accurate, shows that there is an implicit contradiction in it
(D) By pointing out that the advertiser's point of view is biased
(E) By arguing that the advertiser too narrowly restricts the discussion to the effects of advertising that are economic
而C的意思是:消费者提出了一种对Advertiser's opening statement 的解释,指出了opening statement 中内在的矛盾. 但实际上消费者并没有指出Advertiser's statement 中有什么内在矛盾阿?? 如果C改成 By offering an interpretation of the advertiser's statement to show the actual origin of the advertising costs.
