2-1 Hunter: Hunters alone are blamed for the decline in Greenrock National Forest’s deer population over the past ten years. Yet clearly, black bears have also played an important role in this decline. In the past ten years, the forest’s protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer. In the hunter’s argument, the boldface portion plays which of the following roles? - It is the main conclusion of the argument.
- It is an objection that has been raised against the main conclusion of the argument.
- It is a judgment that the argument opposes.
- It is a finding that the argument seeks to explain.
- It provides evidence in support of the main conclusion of the argument.
2-2 Which of the following most logically completes the passage? Garnet and RenCo each provide health care for their employees. Garnet pays for both testing of its employees’ cholesterol levels and treatment of high cholesterol. This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment. However, RenCo dose not have the same financial incentive to adopt such a policy, because ______. - early treatment of high cholesterol dose not entirely eliminate the possibility of a stroke later in life
- the mass media regularly feature stories encouraging people to maintain diets that are low in cholesterol
- RenCo has significantly more employees than Garnet has
- RenCo’s employees are unlikely to have higher cholesterol levels than Garnet’s employees
- the average length of time an employee stays with RenCo is less than it is with Garnet
2-3 Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit-card logo. Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available. Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies? - The effect noted in the studies is not limited to patrons who have credit cards.
- Patrons who are under financial pressure from their credit-card obligations tend to tip less when presented with a restaurant bill on a tray with credit-card logo than when the tray has no logo.
- In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.
- In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.
- The percentage of restaurant bills paid with given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is prepared.
2-4 Economist: Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there become useless for grazing after just a few years. The company has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact. Thus, some environmentalists conclude that Tropicorp has not acted wholly out of economic self-interest. However, these environmentalists are probably wrong. The initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch. Furthermore, there is a shortage of workers employable in rubber-tapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching. In the economist’s argument, the two boldfacedportions play which of the following roles? - The first supports the conclusion of the economist’s argument; the second calls that conclusion into question.
- The first states the conclusion of the economist’s argument; the second supports that conclusion.
- The first supports the environmentalists’ conclusion; the second states that conclusion.
- The first states the environmentalists’ conclusion; the second states the conclusion of the economist’s argument.
- Each supports the conclusion of the economist’s argument.
2-5 (Weaken题变体) Brochure: Help conserve our city’s water supply. By converting the landscaping in your yard to a water-conserving landscape, you can greatly reduce your outdoor water use. A water-conserving landscape is natural and attractive, and it also saves you money. Criticism: For most people with yards, the savings from converting to a water-conserving landscape cannot justify the expense of new landscaping, since typically the conversion would save less than twenty dollars on a homeowner’s yearly water bills. Which of the following, if true, provides the best basis for a rebuttal of the criticism? - Even homeowners whose yards do not have water-conserving landscapes can conserve water by installing water-saving devices in their homes.
- A conventional landscape generally requires a much greater expenditure on fertilizer and herbicide than does a water-conserving landscape.
- A significant proportion of the residents of the city live in buildings that do not have yards.
- It costs no more to put in water-conserving landscaping than it does to put in conventional landscaping.
- Some homeowners use more water to maintain their yards than they use for all other purposes combined.
2-6 Which of following most logically completes the argument? The last members of a now-extinct species of a European wild deer called the giant dear lived in Ireland about 16,000 years ago. Prehistoric cave paintings in France depict this animal as having a large hump on its back. Fossils of this animal, however, do not show any hump. Nevertheless, there is no reason to conclude that the cave paintings are therefore inaccurate in this regard, since ______. - some prehistoric cave paintings in France also depict other animals as having a hump
- fossils of the giant deer are much more common in Ireland than in France
- animal humps are composed of fatty tissue, which dose not fossilize
- the cave paintings of the giant deer were painted well before 16,000 years ago
- only one currently existing species of deer has any anatomical feature that even remotely resembles a hump
2-7 Shipping Clerk: The five specially ordered shipments sent out last week were sent out on Thursday. Last week, all of the shipments that were sent out on Friday consisted entirely of building supplies, and the shipping department then closed for the weekend. Four shipments were sent to Truax Construction last week, only three of which consisted of building supplies. If the shipping clerk’s statements are true, which of the following must also be true? - At least one of the shipments sent to Truax Construction last week was specially ordered.
- At least one of last week’s specially ordered shipments did not consist of building supplies.
- At least one of the shipments sent to Truax Construction was not sent out on Thursday of last week.
- At least one of the shipments that were sent out on Friday of last week was sent to Truax Construction.
- At least one of the shipments sent to Truax Construction last week was sent out before Friday.
2-8 Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting. In an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years. Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes. The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan? - The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.
- Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously.
- The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years.
- The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years.
- The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years.
2-9 Newspaper editorial: In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher. Part of this effort has been to deny inmates the access they formerly had to college-level courses. However, this action is clearly counter to the governor’s ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates. Which of the following is an assumption on which the argument depends? - Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.
- Former inmates are no more likely to commit crimes than are members of the general population.
- The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released.
- Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.
- The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.
2-10 Kate: The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations. Scott: The population of the spruce budworm, the warbler’s favorite prey in North America, has been dropping. This is a more likely explanation of the warbler’s decline. Which of the following, if true, most seriously calls Scott’s hypothesis into question? - The numbers of the Baltimore oriole, a songbird that dose not eat budworms but is as dependent on South American coffee plantations as is the Tennessee warbler, are declining.
- The spruce-budworm population has dropped because of a disease that can infect budworms but not Tennessee warblers.
- The drop in the population of the spruce budworm is expected to be only temporary.
- Many Tennessee warbler have begun migrating in the fall to places other than traditional coffee plantations.
- Although many North American songbirds have declined in numbers, no other species has experienced as great a decline as has the Tennessee warbler.
