Many people with stroke-related aphasia recover at least some capacity to use language within a year. One proposed explanation for such recoveries is that the right side of the brain, which is not usually the major language center, develops its latent language capabilities to compensate for the damage to the left side. Which of the following, if true, most strongly supports the explanation? (A) In a study of local brain activity in people performing a language task, people with strokerelated aphasia showed higher activity levels in the right half of the brain than people who did not have aphasia. (B) A blow to the head injuring the left half of the brain can result in impairment of the capacity to use language indistinguishable from that produced by a stroke. (C) Among people with stroke-related aphasia, recovering lost capacity to use language does not lead to any impairment of those capacities normally controlled by the right half of the brain. (D) A stroke that damages the left half of the brain often causes physical impairments of the right side of the body that lessen over time. (E) Studies of numerous people with aphasia have indicated that the functions that govern language production and those that govern language comprehension are located in separate areas of the brain. Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Question 2 You've got 0 points In the arid land along the Colorado River, use of the river's water supply is strictly controlled: farms along the river each have a limited allocation that they are allowed to use for irrigation. But the trees that grow in narrow strips along the river's banks also use its water. Clearly, therefore, if farmers were to remove those trees, more water would be available for crop irrigation. Which of the following, if true, most seriously weakens the argument? (A) The trees along the river's banks shelter it from the sun and wind, thereby greatly reducing the amount of water lost through evaporation. (B) Owners of farms along the river will probably not undertake the expense of cutting down trees along the banks unless they are granted a greater allocation of water in return. (C) Many of the tree species currently found along the river's banks are specifi cally adapted to growing in places where tree roots remain constantly wet. (D) The strip of land where trees grow along the river's banks would not be suitable for growing crops if the trees were removed. (E) The distribution of water allocations for irrigation is intended to prevent farms farther upstream from using water needed by farms farther downstream. Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Question 3 You've got 0 points Near Chicago a newly built hydroponic spinach "factory," a completely controlled environment for growing spinach, produces on 1 acre of fl oor space what it takes 100 acres of fi elds to produce. Expenses, especially for electricity, are high, however, and the spinach produced costs about four times as much as washed California fi eld spinach, the spinach commonly sold throughout the United States. Which of the following, if true, best supports a projection that the spinach-growing facility near Chicago will be profi table? (A) Once the operators of the facility are experienced, they will be able to cut operating expenses by about 25 percent. (B) There is virtually no scope for any further reduction in the cost per pound for California field spinach. (C) Unlike washed fi eld spinach, the hydroponically grown spinach is untainted by any pesticides or herbicides and thus will sell at exceptionally high prices to such customers as health food restaurants. (D) Since spinach is a crop that ships relatively well, the market for the hydroponically grown spinach is no more limited to the Chicago area than the market for California fi eld spinach is to California. (E) A second hydroponic facility is being built in Canada, taking advantage of inexpensive electricity and high vegetable prices. Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Question 4 You've got 1 point Automobile Dealer's Advertisement: The Highway Traffi c Safety Institute reports that the PZ 1000 has the fewest injuries per accident of any car in its class. This shows that the PZ 1000 is one of the safest cars available today. Which of the following, if true, most seriously weakens the argument in the advertisement? (A) The Highway Traffi c Safety Institute report listed many cars in other classes that had more injuries per accident than did the PZ 1000. (B) In recent years many more PZ 1000s have been sold than have any other kind of car in its class. (C) Cars in the class to which the PZ 1000 belongs are more likely to be involved in accidents than are other types of cars. (D) The difference between the number of injuries per accident for the PZ 1000 and that for other cars in its class is quite pronounced. (E) The Highway Traffi c Safety Institute issues reports only once a year. Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Question 5 You've got 0 points Which of the following most logically completes the reasoning? Either food scarcity or excessive hunting can threaten a population of animals. If the group faces food scarcity, individuals in the group will reach reproductive maturity later than otherwise. If the group faces excessive hunting, individuals that reach reproductive maturity earlier will come to predominate. Therefore, it should be possible to determine whether prehistoric mastodons became extinct because of food scarcity or human hunting, since there are fossilized mastodon remains from both before and after mastodon populations declined, and . (A) there are more fossilized mastodon remains from the period before mastodon populations began to decline than from after that period (B) the average age at which mastodons from a given period reached reproductive maturity can be established from their fossilized remains (C) it can be accurately estimated from fossilized remains when mastodons became extinct (D) it is not known when humans fi rst began hunting mastodons (E) climate changes may have gradually reduced the food available to mastodons Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Question 6 You've got 0 points Editorial: The mayor plans to deactivate the city's fi re alarm boxes, because most calls received from them are false alarms. The mayor claims that the alarm boxes are no longer necessary, since most people now have access to either public or private telephones. But the city's commercial district, where there is the greatest risk of fi re, has few residents and few public telephones, so some alarm boxes are still necessary. Which of the following, if true, most seriously weakens the editorial's argument? (A) Maintaining the fi re alarm boxes costs the city more than fi ve million dollars annually. (B) Commercial buildings have automatic fi re alarm systems that are linked directly to the fi re department. (C) The fi re department gets less information from an alarm box than it does from a telephone call. (D) The city's fi re department is located much closer to the residential areas than to the commercial district. (E) On average, almost 25 percent of the public telephones in the city are out of order. Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Question 7 You've got 0 points State spokesperson: Many businesspeople who have not been to our state believe that we have an inadequate road system. Those people are mistaken, as is obvious from the fact that in each of the past six years, our state has spent more money per mile on road improvements than any other state. Which of the following, if true, most seriously undermines the reasoning in the spokesperson's argument? (A) In the spokesperson's state, spending on road improvements has been increasing more slowly over the past six years than it has in several other states. (B) Adequacy of a state's road system is generally less important to a businessperson considering doing business there than is the availability of qualifi ed employees. (C) Over the past six years, numerous businesses have left the spokesperson's state, but about as many businesses have moved into the state. (D) In general, the number of miles of road in a state's road system depends on both the area and the population of the state. (E) Only states with seriously inadequate road systems need to spend large amounts of money on road improvements. Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Question 8 You've got 0 points Company Alpha buys free-travel coupons from people who are awarded the coupons by Bravo Airlines for fl ying frequently on Bravo airplanes. The coupons are sold to people who pay less for the coupons than they would pay by purchasing tickets from Bravo. This marketing of coupons results in lost revenue for Bravo. To discourage the buying and selling of free-travel coupons, it would be best for Bravo Airlines to restrict the (A) number of coupons that a person can be awarded in a particular year (B) use of the coupons to those who were awarded the coupons and members of their immediate families (C) days that the coupons can be used to Monday through Friday (D) amount of time that the coupons can be used after they are issued (E) number of routes on which travelers can use the coupons Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Question 9 You've got 0 points Pro-Tect Insurance Company has recently been paying out more on car-theft claims than it expected. Cars with special antitheft devices or alarm systems are much less likely to be stolen than are other cars. Consequently Pro-Tect, as part of an effort to reduce its annual payouts, will offer a discount to holders of car-theft policies if their cars have antitheft devices or alarm systems. Which of the following, if true, provides the strongest indication that the plan is likely to achieve its goal? (A) The decrease in the risk of car theft conferred by having a car alarm is greatest when only a few cars have such alarms. (B) The number of policyholders who have fi led a claim in the past year is higher for Pro-Tect than for other insurance companies. (C) In one or two years, the discount that Pro-Tect is offering will amount to more than the cost of buying certain highly effective antitheft devices. (D) Currently, Pro-Tect cannot legally raise the premiums it charges for a given amount of insurance against car theft. (E) The amount Pro-Tect has been paying out on cartheft claims has been greater for some models of car than for others. Answer 1 Answer 2 Answer 3 Answer 4 Answer 5 Question 10 You've got 1 point Toughened hiring standards have not been the primary cause of the present staffi ng shortage in public schools.
