第一部分是OG习题
1.
Snowmaking machines work by spraying a mistthat freezes immediately on contact with cold air. Because the sudden freezingkills bacteria, QuickFreeze is planning to market a wastewater purificationsystem that works on the same principle. The process works only whentemperatures are cold, however, so municipalities using it will still need tomaintain a conventional system.
Which of the following, if true, providesthe strongest grounds for a prediction that municipalities will buyQuickFreeze's purification system despite the need to maintain a conventionalpurification system as well?
A Bacteriaare not the only impurities that must be removed from wastewater.
B Manymunicipalities have old wastewater purification systems that need to bereplaced.
C  Conventional wastewater purification systemshave not been fully successful in killing bacteria at cold temperatures.
D  During times of warm weather, when it is notin use, QuickFreeze's purification system requires relatively littlemaintenance.
E  Placeswhere the winters are cold rarely have a problem of water shortage.

2.
Homeowners aged 40 to 50 are more likely topurchase ice cream and are more likely to purchase it in larger amounts thanare members of any other demographic group. The popular belief that teenagerseat more ice cream than adults must, therefore, be false.

The argument is flawed primarily becausethe author
A  fails to distinguish between purchasing andconsuming
B  does not supply information about homeownersin age groups other than 40 to 50
C  depends on popular belief rather than ondocumented research findings
D  does not specify the precise amount of icecream purchased by any demographic group
E  discussesice cream rather than more nutritious and healthful foods

第二部分是prep07题

2.
Economist:  Onaverage, the emergency treatment for an elderly person for injuries resultingfrom a fall costs $11,000.  A newtherapeutic program can significantly reduce an elderly person's chances offalling.  Though obviously desirable formany reasons, this treatment program will cost $12,500 and thus cannot bejustified.
Which of the following, if true, most seriouslyundermines the conclusion of the argument?
(A) Among elderly people who had followed the program foronly a few months, the number of serious falls reported was higher than it wasfor people who had followed the program for its recommended minimum length ofone year.
(B) Falls resulting in serious injuries are less commonamong elderly people living in nursing homes than they are among elderly peoplewho live alone at home.
(C) A frequent result of injuries sustained in falls islong-term pain, medication for which is not counted among the averageper-person costs of emergency treatment for elderly people's injuries from suchfalls.
(D) The new therapeutic program focuses on therapiesother than medication, since overmedication can cause disorientation and henceincrease the likelihood that an elderly person will have a serious fall.
(E) A significant portion of the cost of the newtherapeutic program is represented by regular visits by health care professionals,the costs of which tend to increase more rapidly than do those of otherelements of the program.

10.
Jennifer:  Videorental outlets in Centerville together handled 10,000 fewer video rentals in1994 than in 1993.  The decline inrentals was probably due almost entirely to the February 1994 opening ofVideorama, the first and only video rental outlet in the area that, in additionto renting videos, also sold them cheaply.

Brad:  There mustbe another explanation:  as you yourselfsaid, the decline was on the order of 10,000 rentals.  Yet Videorama sold only 4,000 videos in 1994.

Which of the following, if true, would most seriouslyweaken the force of the objection that Brad presents to Jennifer's explanation?

(A) In 1994 Videorama rented out more videos than itsold.
(B) In 1994 two new outlets that rent but that do notsell videos opened in Centerville.
(C) Most of the video rental outlets in Centerville rentvideos at a discount on certain nights of the week.
(D) People often buy videos of movies that they havepreviously seen in a theater.
(E) People who own videos frequently loan them totheir friends.

第三部分是GWD题

A productthat represents a clear technological advance over competing products cangenerally command a high price.  Because technological advances tend to be quicklysurpassed and companies want to make large profits while they still can,many companies charge the greatest price the market will bear when they havesuch a product.  But large profits on the mew product will give competitors a strongincentive to quickly match the mew product’s capabilities.  Consequently, the strategy to maximizeoverall profit from a new product is to charge less than the greatest possibleprice.
In theargument above, the two portions in boldfaceplay which of the following roles?
A.   The first is an assumption that forms thebasis for a course of action that the argument criticizes; the second presents thecourse of action endorsed by the argument.
B.   The first is a consideration raised toexplain the appeal of a certain strategy; the second is a consideration raisedto call into question the wisdom of adopting that strategy.
C.   The first is an assumption that has beenused to justify a certain strategy; the second is a consideration that is usedto cast doubt on that assumption.
D.   The first is a consideration raised insupport of a strategy the argument endorses; the second presents grounds insupport of that consideration.
E.    The first is a consideration raised to showthat adopting a certain strategy is unlikely to achieve the intended effect;the second is presented to explain the appeal of that strategy.

In partsof South America, vitamin-A deficiency is aserious health problem, especially among children.  In one region, agriculturists are attemptingto improve nutrition by encouraging farmers to plant a new variety of sweetpotato called SPK004 that is rich in beta-carotene, which the body convertsinto vitamin A.  The plan has goodchances of success, since sweet potato is a staple of the region’s diet andagriculture, and the varieties currently grown contain little beta-carotene.
Which ofthe following, if true, most strongly supports the prediction that the planwill succeed?
A.   The growing conditions required by thevarieties of sweet potato currently cultivated in the region are conditions inwhich SPK004 can flourish.
B.   The flesh of SPK004 differs from that of thecurrently cultivated sweet potatoes in color and texture, so traditional foodswould look somewhat different when prepared from SPK004.
C.   There are no other varieties of sweet potatothat are significantly richer in beta-carotene than SPK004 is.
D.   The varieties of sweet potato currentlycultivated in the region contain some important nutrients that are lacking inSPK004.
E.    There are other vegetables currently grownin the region that contain more beta-carotene than the currently cultivatedvarieties of sweet potato do.
