那我先来问一个~
GWD1-Q3:
A 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 who 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 new product will give competitors a strong incentive to quickly match the new 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.

Most of the world's supply of uranium currently comes from mines.  It is possible to extract uranium from seawater, but the cost of doing so is greater than the price that uranium fetches on the world market.  Therefore, until the cost of extracting uranium from seawater can somehow be reduced, this method of obtaining uranium is unlikely to be commercially viable.

Which of the following would it be most useful to determine in evaluating the argument?
a. Whether the uranium in deposits on land is rapidly being depleted
b. Whether most uranium is used near where it is mined
c. Whether there are any technological advances that show promise of reducing the cost of extracting uranium from seawater
d. Whether the total amount of uranium in seawater is significantly greater than the total amount of uranium on land
e. Whether uranium can be extracted from freshwater at a cost similar to the cost of extracting it from seawater

most useful to determine in evaluating the argument?<--我不懂这个题目要我evaluate什么。求解。

48. If the county continues to collect residential trash at current levels, landfills will soon be overflowing and parkland will need to be used in order to create more space. Charging each household a fee for each pound of trash it puts out for collection will induce residents to reduce the amount of trash they create; this charge will therefore protect the remaining county parkland。
Which of the following is an assumption made in drawing the conclusion above?
(A)Residents will reduce the amount of trash they put out for collection by reducing the number of products they buy.
(B) The collection fee will not significantly affect the purchasing power of most residents, even if their households do not reduce the amount of trash they put out.
(C） The collection fee will not induce residents to dump their trash in the parklands illegally.
(D) The beauty of county parkland is an important issue for most of the county’s residents.
(E) Landfills outside the county’s borders could be used as dumping sites for the county’s trash.

我觉得A和C 都对，可为啥A不对呢。。因为A说居民最终都减少了垃圾的排放，所以我认为支持了结论啊。。。跪求楼主解答！！

我的思路是先看问题假设，然后提干，collect residential trash.. landfills will over flow… so a plan: fee will help con: the trash will be reduced.
48. If the county continues to collect residential trash at current levels, landfills will soon be overflowing and parkland will need to be used in order to create more space.

Which of the following is an assumption made in drawing the conclusion above?
(A)Residents will reduce the amount of trash they put out for collection by reducing the number of products they buy. 这个没有用呀，或者说无关题目，只是再说citizens will reduce amount of trash…, by a meanà reduce what they bought. 这个和整体计划实行没有关，包括到原文最后一句话，也是一样的。

我认为这个需要搞清楚整个逻辑链条，
(B) The collection fee will not significantly affect the purchasing power of most residents, even if their households do not reduce the amount of trash they put out.
(C） The collection fee will not induce residents to dump their trash in the parklands illegally. 很明显，对的，因为这就是从题目逻辑条出发的意思是将不会非法倾倒垃圾
(D) The beauty of county parkland is an， important issue for most of the county’s residents.
(E) Landfills outside the county’s borders could be used as dumping sites for the county’s trash.

求解：新PREP逻辑，Part2-78，84，85

78.    (32009-!-item-!-188;#058&006754)

Kitchen magazine plans to license the use of its name by a line of cookware.  For a magazine, licensing the use of its name for products involves some danger, since if the products disappoint consumers, the magazine's reputation suffers, with consequent reductions in circulation and advertising.  However, experts have evaluated the cookware and found it superior to all other cookware advertised in Kitchen.  Therefore, Kitchen can collect its licensing fee without endangering its other revenues.
The argument above assumes which of the following?
A. No other line of cookware is superior to that which will carry the Kitchen name.
B. Kitchen will not license the use of its name for any products other than the line of cookware.
C. Makers of cookware will not find Kitchen a less attractive advertising vehicle because the magazine's name is associated with a competing product.
D. Consumers who are not regular readers of Kitchen magazine will be attracted to the cookware by the Kitchen name.
E. Kitchen is one of the most prestigious cooking-related magazines.
求解B为什么不选.

The general availability of high-quality electronic scanners and color printers for computers has made the counterfeiting of checks much easier.  In order to deter such counterfeiting, several banks plan to issue to their corporate customers checks that contain dots too small to be accurately duplicated by any electronic scanner currently available; when such checks are scanned and printed, the dots seem to blend together in such a way that the word “VOID” appears on the check.
A questionable assumption of the plan is that
A. in the territory served by the banks the proportion of counterfeit checks that are made using electronic scanners has remained approximately constant over the past few years
B. most counterfeiters who use electronic scanners counterfeit checks only for relatively large amounts of money
C. the smallest dots on the proposed checks cannot be distinguished visually except under strong magnification
D. most corporations served by these banks will not have to pay more for the new checks than for traditional checks
E. the size of the smallest dots that generally available electronic scanners are able to reproduce accurately will not decrease significantly in the near future
