Companies O and P each have the same number of employees who work the same number of hours per week. According to records maintained by each company, the employees of Company O had fewer job-related accidents last year than did the employees of Company P. Therefore, employees of Company O are less likely to have job-related accidents than are employees of Company P.Which of the following, if true, would most weaken the conclusion above?
Adult female rats who have never before encountered rat pups will start to show maternal behaviors after being confined with a pup for about seven days. This period can be considerably shortened by disabling the female's sense of smell or by removing the scent-producing glands of the pup.Which of the following hypotheses best explains the contrast described above?
Sales of telephones have increased dramatically over the last year. In order to take advantage of this increase, Mammoth Industries plans to expand production of its own model of telephone, while continuing its already very extensive advertising of this product.Which of the following, if true, provides most support for the view that Mammoth Industries cannot increase its sales of telephones by adopting the plan outlined above?
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.The economist's argument makes which of the following assumptions?
A drug that is highly effective in treating many types of infection can, at present, be obtained only from the bark of the ibora, a tree that is quite rare in the wild. It takes the bark of 5,000 trees to make one kilogram of the drug. It follows, therefore, that continued production of the drug must inevitably lead to the ibora's extinction.Which of the following, if true, most seriously weakens the argument above?
Manufacturers sometimes discount the price of a product to retailers for a promotion period when the product is advertised to consumers.Such promotions often result in a dramatic increase in amount of product sold by the manufacturers to retailers.Nevertheless.the manufacturers could often make more profit by not holding the promotions.Which of the following, if true, most strongly supports the claim above about the manufacturers' profit?
Excavation of the ancient city of Kourion on the island of Cyprus revealed a pattern of debris and collapsed buildings typical of towns devastated by earthquakes. Archaeologists have hypothesized that the destruction was due to a major earthquake known to have occurred near the island in AD 365.Which of the following, if true, most strongly supports the archaeologists' hypothesis?
According to a review of 61 studies of patients suffering from severely debilitating depression, a large majority of the patients reported that missing a night's sleep immediately lifted their depression. Yet sleep-deprivation is not used to treat depression even though the conventional treatments, which use drugs and electric shocks, often have serious side effects.Which of the following, if true, best explains the fact that sleep-deprivation is not used as a treatment for depression?
In many corporations, employees are being replaced by automated equipment in order to save money. However, many workers who lose their jobs to automation will need government assistance to survive, and the same corporations that are laying people off will eventually pay for that assistance through increased taxes and unemployment insurance payments.Which of the following, if true, most strengthens the author's argument?
United States hospitals have traditionally relied primarily on revenues from paying patients to offset losses from unreimbursed care.Almost all paying patients now rely on governmental or private health insurance to pay hospital bill. Recently, insurers have been strictly limiting what they pay hospitals for the care of insured patients to amounts at or below actual costs.Which of the following conclusions is best supported by the information above?
On Pacific islands, a newly arrived gecko species, the house gecko, is displacing the previously established mourning gecko in urban areas, but populations of the two species are more stable in rural areas far from human settlement. The house gecko does not attack the mourning gecko, but in areas where insects congregate it prevents the mourning gecko from feeding on them.Which of the following contributes most to an explanation of the difference between gecko populations in urban and rural areas?
Downtown Villieu was once a flourishing business district, but most Villieu-area businesses are now located only in the suburbs. The office buildings downtown lack the modern amenities most business operators demand today. To lure more businesses downtown, Villieu officials plan to have several modern office buildings constructed and to offer reduced local tax rates to any business that leases space in a new downtown building.Which of the following, if true, most threatens the plan's likelihood of success?
Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested. NorthernAir depends for its success on economy and quick turnaround and consequently is planning to replace its largeplanes with Skybuses, whose novel aerodynamic design is extremely fuel efficient. The Skybus' fuel efficiency results in both lower fuel costs and reduced time spent refueling.Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses?
Which of the following most logically completes the argument?A new machine for harvesting corn will allow rows to be planted only fifteen inches apart, instead of the usual thirty inches. Corn planted this closely will produce lower yields per plant. Nevertheless, the new machine will allow corn growers to double their profits per acre because __________.
Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of ice and enough seawater, which contains nutrients, reaches that layer after splashing onto the surface. Even though moderate snow cover reduces the sunlight that filters into the top layer, sea ice with moderate snow cover typically contains even more algae in the top layer than does sea ice with less snow cover.Which of the following, if true, most helps to explain the apparent discrepancy?
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 does not have the same financial incentive to adopt such a policy, because ______.
United Lumber will use trees from its forests for two products. The tree trunks will be used for lumber and the branches converted into wood chips to make fiberboard. The cost of this conversion would be the same whether done at the logging site, where the trees are debranched, or at United's factory. However, wood chips occupy less than half the volume of the branches from which they are made.The information given, if accurate, most strongly supports which of the following?
Which of the following most logically completes the argument?Utrania was formerly a major petroleum exporter, but in recent decades economic stagnation and restrictive regulations inhibited investment in new oil fields. In consequence, Utranian oil exports dropped steadily as old fields became depleted. Utrania's currently improving economic situation, together with less-restrictive regulations, will undoubtedly result in the rapid development of new fields. However, it would be premature to conclude that the rapid development of new fields will result in higher oil exports, because __________.
Beta Corporation claims that it no longer has enough work for the 60 computer data-entry workers that it is laying off. These workers have heard, however, that the company is buying 100 new computers. So the workers concluded that the company's real reason for laying them off is to fill their jobs with lower-paid workers.Which of the following, if true, would most undermine the workers' conclusion?
