41	In comparison to the standard typewriter keyboard, the EFCO keyboard, which places the most-used keys nearest the typist`s strongest fingers, allows faster typing and results in less fatigue. Therefore, replacement of standard keyboards with the EFCO keyboard will result in an immediate reduction of typing costs.Which of the following, if true, would most weaken the conclusion drawn above?
42	Researchers have found that when very overweight people, who tend to have relatively low metabolic rates, lose weight primarily through dieting, their metabolisms generally remain unchanged. They will thus burn significantly fewer calories at the new weight than do people whose weight is normally at that level. Such newly thin persons will, therefore, ultimately regain weight until their body size again matches their metabolic rate.The conclusion of the argument above depends on which of the following assumptions?
43	Half of the subjects in an experiment-the experimental group-consumed large quantities of a popular artificial sweetener. Afterward, this group showed lower cognitive abilities than did the other half of the subjects-the control group who did not consume the sweetener. The detrimental effects were attributed to an amino acid that is one of the sweetener's principal constituents.Which of the following, if true, would best support the conclusion that some ingredient of the sweetener was responsible for the experimental results?
44	Half of the subjects in an experiment-the experimental group-consumed large quantities of a popular artificial sweetener.Afterward, this group showed lower cognitive abilities than did the other half of the subjects-the control group.who did not consume the sweetener.The detrimental effects were attributed to an amino acid that is one of the sweetener's principal constituents.Which of the following, if true, would best help explain how the sweetener might produce the observed effect?
45	The recent decline in the value of the dollar was triggered by a prediction of slower economic growth in the coming year. But that prediction would not have adversely affected the dollar had it not been for the government's huge budget deficit, which must therefore be decreased to prevent future currency declines.Which of the following, if true, would most seriously weaken the conclusion about how to prevent future currency declines?
46	Neither a rising standard of living nor balanced trade, by itself, establishes a country`s ability to compete in the international marketplace. Both are required simultaneously since standards of living can rise because of growing trade deficits and trade can be balanced by means of a decline in a country`s standard of living.If the facts stated in the passage above are true, a proper test of a country`s ability to be competitive is its ability to
47	Traditionally, decision making by managers that is reasoned step-by-step has been considered preferable to intuitive decision making.However, a recent study found that top managers used intuition significantly more than did most middle-or lower-level managers.This confirms the alternative view that intuition is actually more effective than careful, methodical reasoning.The conclusion above is based on which of the following assumptions?
48	Certain messenger molecules fight damage to the lungs from noxious air by telling the muscle cells encircling the lungs'airways to contract.This partially seals off the lungs.An asthma attack occurs when the messenger molecules are activated unnecessarily, in response to harmless things like pollen or household dust.Which of the following, if true, points to the most serious flaw of a plan to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules referred to above?
49	Start-up companies financed by venture capitalists have a much lower failure rate than companies financed by other means. Source of financing, therefore, must be a more important causative factor in the success of a start-up company than are such factors as the personal characteristics of the entrepreneur, the quality of strategic planning, or the management structure of the company.Which of the following, if true, most seriously weakens the argument above?
50	When people evade income taxes by not declaring taxable income, a vicious cycle results. Tax evasion forces lawmakers to raise income tax rates, which causes the tax burden on nonevading taxpayers to become heavier. This, in turn, encourages even more taxpayers to evade income taxes by hiding taxable income.The vicious cycle described above could not result unless which of the following were true?
51	Because postage rates are rising, Home Decorator magazine plans to maximize its profits by reducing by one-half the number of issues it publishes each year.The quality of articles, the number of articles published per year, and the subscription price will not change.Market research shows that neither subscribers nor advertisers will be lost if the magazine's plan is instituted.Which of the following, if true, provides the strongest evidence that the magazine's profits are likely to decline if the plan is instituted?
52	When three Everett-owned Lightning-built airplanes crashed in the same month, the Everett company ordered three new Lightning-built airplanes as replacements. This decision surprised many in the airline industry because, ordinarily when a product is involved in accidents, users become reluctant to buy that product.Which of the following, if true, provides the best indication that the Everett company's decision was logically well supported?
53	Unlike the wholesale price of raw wool, the wholesale price of raw cotton has fallen considerably in the last year. Thus, although the retail price of cotton clothing at retail clothing stores has not yet fallen, it will inevitably fall.Which of the following, if true, most seriously weakens the argument above?
54	The pharmaceutical industry argues that because new drugs will not be developed unless heavy development costs can be recouped in later sales, the current 20 years of protection provided by patents should be extended in the case of newly developed drugs. However, in other industries new-product development continues despite high development costs, a fact that indicates that the extension is unnecessary.Which of the following, if true, most strongly supports the pharmaceutical industry`s argument against the challenge made above?
55	The cotton farms of Country Q became so productive that the market could not absorb all that they produced. Consequently, cotton prices fell. The government tried to boost cotton prices by offering farmers who took 25 percent of their cotton acreage out of production direct support payments up to a specified maximum per farm.The government's program, if successful, will not be a net burden on the budget. Which of the following, if true, is the best basis for an explanation of how this could be so?
56	Robot satellites relay important communications and identify weather patterns. Because the satellites can be repaired only in orbit, astronauts are needed to repair them. Without repairs, the satellites would eventually malfunction. Therefore, space flights carrying astronauts must continue.Which of the following, if true, would most seriously weaken the argument above?
57	Since the deregulation of airlines, delays at the nation's increasingly busy airports have increased by 25 percent.To combat this problem, more of the takeoff and landing slots at the busiest airports must be allocated to commercial airlines.Which of the following, if true, casts the most doubt on the effectiveness of the solution proposed above?
58	The proposal to hire ten new police officers in Middletown is quite foolish. There is sufficient funding to pay the salaries of the new officers, but not the salaries of additional court and prison employees to process the increased caseload of arrests and convictions that new officers usually generate.>Which of the following, if true, will most seriously weaken the conclusion drawn above?
59	Bank depositors in the United States are all financially protected against bank failure because the government insures all individuals' bank deposits.An economist argues that this insurance is partly responsible for the high rate of bank failures, since it removes from depositors any financial incentive to find out whether the bank that holds their money is secure against failure.If depositors were more selective.then banks would need to be secure in order to compete for depositors' money.Which of he following, if true, most seriously weakens the economist s argument?
60	Large national budget deficits do not cause large trade deficits.If they did, countries with the largest budget deficits would also have the largest trade deficits.In fact, when deficit figures are adjusted so that different countries are reliably comparable to each other, there is no such correlation.If the statements above are all true, which of the following can properly be inferred on the basis of them?
