2、presents 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 ha

3、ve such a product. But large profits on the mew product will give competitors a strong incentive to quickly match the mew products 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

4、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.

5、trategy; 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

6、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.-GWD

7、1-Q22:City Official: At City Hospital, uninsured patients tend to have shorter stays and fewer procedures performed than do insured patients, even though insured patients, on average, have slightly less serious medical problems at the time of admission to the hospital than uninsured patients have. C

8、ritics of the hospital have concluded that the uninsured patients are not receiving proper medical care. However, this conclusion is almost certainly false. Careful investigation has recently shown two things: insured patients have much longer stays in the hospital than necessary, and they tend to h

9、ave more procedures performed than are medically necessary.In the city officials argument, the two boldface portions play which of the following roles?A.

12、when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years. Since many local businesses in Florida cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses.Which of the following, if tru

13、e, most seriously weakens the argument?A. Florida attracts more people who move from one state to another when they retire than does any other state.B. The number of people who move out of Florida to accept employment in other states has increased over the past ten years.C. There are far more local

14、businesses in Florida that cater to tourists than there are local businesses that cater to retirees.D.

15、 to live in another state was greater last year than it was ten years ago.-GWD1-Q14:That the application of new technology can increase the productivity of existing coal mines is demonstrated by the case of Tribnias coal industry. Coal output per miner in Tribnia is double what it was five years ago

16、, even though no new mines have opened.Which of the following can be properly concluded from the statement about coal output per miner in the passage?A. If the number of miners working in Tribnian coal mines has remained constant in the past five years, Tribnias total coal production has doubled in

17、that period of time.B. Any individual Tribnian coal mine that achieved an increase in overall output in the past five years has also experienced an increase in output per miner.C. If any new coal mines had opened in Tribnia in the past five years, then the increase in output per miner would have bee

18、n even greater than it actually was.D. If any individual Tribnian coal mine has not increased its output per miner in the past five years, then that mines overall output has declined or remained constant.E. In Tribnia the cost of producing a given quantity of coal has declined over the past five yea

19、rs. -GWD1-Q15:In parts of South America, vitamin-A deficiency is a serious health problem, especially among children. In one region, agriculturists are attempting to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in beta-carotene, which the

20、 body converts into vitamin A. The plan has good chances of success, since sweet potato is a staple of the regions diet and agriculture, and the varieties currently grown contain little beta-carotene.Which of the following, if true, most strongly supports the prediction that the plan will succeed?A.

21、 The growing conditions required by the varieties of sweet potato currently cultivated in the region are conditions in which SPK004 can flourish.B. The flesh of SPK004 differs from that of the currently cultivated sweet potatoes in color and texture, so traditional foods would look somewhat differen

22、t when prepared from SPK004.C. There are no other varieties of sweet potato that are significantly richer in beta-carotene than SPK004 is.D. The varieties of sweet potato currently cultivated in the region contain some important nutrients that are lacking in SPK004.E. There are other vegetables curr

23、ently grown in the region that contain more beta-carotene than the currently cultivated varieties of sweet potato do.-GWD1-Q17:The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatoni

24、c scalethe seven-note musical scale used in much of Western music since the Renaissance. Musicologists therefore hypothesize that the diatonic musical scale was developed and used thousands of years before it was adopted by Western musicians.Which of the following, if true, most strongly supports th

25、e hypothesis?A. Bone flutes were probably the only musical instrument made by Neanderthals.B. No musical instrument that is known to have used a diatomic scale is of an earlier date than the flute found at the Neanderthal campsite.C. The flute was made from a cave-bear bone and the campsite at which

26、 the flute fragment was excavated was in a cave that also contained skeletal remains of cave bears.D. Flutes are the simplest wind instrument that can be constructed to allow playing a diatonic scale.E. The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a f

27、lute capable of playing a complete diatonic scale.-GWD1-Q18:It is illegal to advertise prescription medications in Hedland except in professional medical journals or by mail directly to physicians. A proposed law would allow general advertising of prescription medications. Opponents object that, in

28、general, laypersons lack the specialized knowledge to evaluate such advertisements and might ask their physicians for inappropriate medications. But since physicians have the final say as to whether to prescribe a medication for a patient, the objection provides no grounds for concern.Which of the f

29、ollowing would it be most useful to establish in order to evaluate the argument?A. Whether nonprescription medications can interact with and block the action of any prescription medications that could be advertised to the general publicB. Whether most prescription medication advertisements directed

30、at the general public would be advertisements for recently developed medications newly available by prescriptionC. Whether prescription medication advertisements directed at the general public would appear on television and radio as well as in printD. Whether physicians are more likely to pay attent

31、ion to advertising directed to the general public than to advertising directed to physiciansE. Whether physicians are likely to succumb to pressure from patients to prescribe inappropriate medications-GWD1-Q31:Which of the following most logically completes the argument below?Davison River farmers a

32、re currently deciding between planting winter wheat this fall or spring wheat next spring. Winter wheat and spring wheat are usually about equally profitable. Because of new government restrictions on the use of Davison River water for irrigation, per acre yields for winter wheat, though not for spr

33、ing wheat, would be much lower than average. Therefore, planting spring wheat will be more profitable than planting winter wheat, since.A. the smaller-than-average size of a winter wheat harvest this year would not be compensated for by higher winter wheat pricesB. new crops of spring wheat must be

34、planted earlier than the time at which standing crops of winter wheat are ready to be harvestedC. the spring wheat that farmers in the Davison River region plant is well adapted to the soil of the regionD. spring wheat has uses that are different from those of winter wheatE. planting spring wheat is

35、 more profitable than planting certain other crops, such as rye-GWD1-Q39:Which of the following most logically completes the passage below?Heavy rains during Centralias corn planting season prevented some farmers there from planting corn. It is now the planting season for soybeans, another of Centra

36、lias principal crops, and those fields originally intended for corn are dry enough for planting. Nonetheless, even though soybean prices are unusually high at present, the farmers will leave most of these fields empty rather than plant them with soybeans, since .A. the extensive rains have led to an

37、 increase in the price of corn B. some Centralian farmers anticipate serious financial losses due to the extremely wet spring planting seasonC. chemicals that were used to prepare the fields for corn planting would stunt the growth of soybeansD. the majority of Centralias corn farmers were able to p

38、lant corn as they had intended, despite the wet planting seasonE. many Centralian farmers grow both corn and soybeans-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 differenc

39、es 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 companys implementing its plan to develop the prototype?A. There is a considerable degree of variati

40、on 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

41、 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 s

42、eason when extensive weeding is not necessary.-GWD1-Q40:Until mow, only injectable vaccines against influenza have been available. Parents 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

43、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

44、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.-GWD-TN-2GWD3-Q2:Hunter: Hunters alone are blamed for the decline in Greenrock National Forests deer population over the pas
