在做GWD的题目时，遇到一些题目，没有看明白，希望大家帮帮忙~谢谢~
1A product that represents a clear technological advance over competing products can generally command a high price. Because technological advances tend to be quickly surpassed and companies want to make large profits while they still can, many companies charge the greatest price the market will bear when they have such a product. But large profits on the mew product will give competitors a strong incentive to quickly match the mew product’s capabilities. Consequently, the strategy to maximize overall profit from a new product is to charge less than the greatest possible price.

In the argument above, the two portions in boldface play which of the following roles?

A. The first is an assumption that forms the basis for a course of action that the argument criticizes; the second presents the course of action endorsed by the argument.

B. The first is a consideration raised to explain the appeal of a certain strategy; the second is a consideration raised to call into question the wisdom of adopting that strategy.

C. The first is an assumption that has been used to justify a certain strategy; the second is a consideration that is used to cast doubt on that assumption.

D. The first is a consideration raised in support of a strategy the argument endorses; the second presents grounds in support of that consideration.

E. The first is a consideration raised to show that adopting a certain strategy is unlikely to achieve the intended effect; the second is presented to explain the appeal of that strategy.

正确答案是B。。。。。额，没有怎么看懂题目的意思？？尤其是那一句，large profits.....?
GWD1-Q33:

A company plans to develop a prototype weeding machine that uses cutting blades with optical sensors and microprocessors that distinguish weeds from crop plants by differences in shade of color. The inventor of the machine claims that it will reduce labor costs by virtually eliminating the need for manual weeding.

Which of the following is a consideration in favor of the company’s implementing its plan to develop the prototype?
A. There is a considerable degree of variation in shade of color between weeds of different species.

B. The shade of color of some plants tends to change appreciably over the course of their growing season.

C. When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds.

D. Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics.

E. Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.
这个题目。。。正确答案是D，可是我真的没有搞明白D的逻辑？？甚至连意思好像都不太明白？
GWD1-Q40:

Until mow, only injectable vaccines against influenza have been available.

arents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated. A new influenza vaccine, administered painlessly in a nasal spray, is effective for children. However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray.

Which of the following is an assumption on which the argument depends?
A. Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.

B. The new vaccine uses the same mechanism to ward off influenza as jnjectable vaccines do.

C. The injectable vaccine is affordable for all adults.

D. Adults do not contract influenza primarily from children who have influenza.

E. The nasal spray vaccine is mot effective when administered to adults.
比较迷惑的一道题，没有搞明白逻辑，我用的是LAWYER的方法，对于充分性的假设题，原则是：文章+选项=must be true.然而，答案是D,我不知道我的判断是否正确，（文章是否是充分型）但是D选项的逻辑好像不太能明白？希望能帮我解释一下，谢谢~~

句子作用题不用读懂题目。

A、B、C为黑体字部分。
在A、B间找有没有转折连词however（大小写均可）、But（大写）、Yet（大写），以及表示原因的because, since等。
A However B 结构：黑体字在However前，与作者立场相反；在However后，与作者立场一致.
A However B However C结构：A和C无关，B与C相反，C为作者态度
But，Yet=However，小写but, yet就当没看到。
Although就当没看到。
Nevertheless，Nonetheless，表然而，部分转折，与However答案类似，但必有区分度。
Because A, B/B, since A结构：A是evidence和explanation去support和explain; B是conclusion, claim, position
conclude, clearly, therefore, B结构： B是结论
选项中的argument指的是整篇文章
如果文中无however, But, Yet大转折词，选项中不应有反对、质疑、拒绝。
