1. Industry experts expect improvements in job safety
training to lead to safer work environments. A recent
survey indicated, however, that for manufacturers
who improved job safety training during the 1980s,
the number of on-the-job accidents tended to
increase in the months immediately following the
changes in the training programs.
Which one of the following, if true, most helps to
resolve the apparent discrepancy in the passage
above?
(A) A similar survey found that the number of onthe-
job accidents remained constant after job
safety training in the transportation sector
was improved.
(B) Manufacturers tend to improve their job safety
training only when they are increasing the
size of their workforce.
(C) Manufacturers tend to improve job safety
training only after they have noticed that the
number of on-the-job accidents has
increased.
(D) It is likely that the increase in the number of
on-the-job accidents experienced by many
companies was not merely a random
fluctuation.
(E) Significant safety measures, such as protective
equipment and government safety
inspections, were in place well before the
improvements in job safety training.

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?
A. It is the main conclusion of the argument.
B. It is an objection that has been raised against the main conclusion of the argument.
C. It is a judgment that the argument opposes.
D. It is a finding that the argument seeks to explain.
E. It provides evidence in support of the main conclusion of the argument.

Early in the twentieth century, Lake Konfa became very polluted. Recently fish populations have recovered as release of industrial pollutants has declined and the lake’s waters have become cleaner. Fears are now being voiced that the planned construction of an oil pipeline across the lake’s bottom might revive pollution and cause the fish population to decline again. However, a technology for preventing leaks is being installed. Therefore, provided this technology is effective, those fears are groundless.
The argument depends on assuming which of the following?
A. Apart from development related to the pipeline, there will be no new industrial development around the lake that will create renewed pollution in its waters.
B. There is no reason to believe that the leak-preventing technology would be ineffective when installed in the pipeline in Lake Konfa.
C. The bottom of the lake does not contain toxic remnants of earlier pollution that will be stirred into the water by pipeline construction.
D. Damage to the lake’s fish populations would be the only harm that a leak of oil from the pipeline would cause.
E. The species of fish that are present in Lake Konfa now are the same as those that were in the lake before it was affected by pollution.

Denoma, a major consumer-electronics maker, had a sizable decline in sales revenue for its most recent fiscal year. This result appears surprising, because electronics retailers report that although their overall sales were considerably lower than in the previous year, their sales revenue from Denoma models actually grew, largely thanks to some innovative and popular models that Denoma introduced.
Which of the following, if true, does most to explain the apparently surprising result?
A. Because of the need to educate the public about its new models’ capabilities, Denoma’s advertising spending was higher than normal over the period.
B. For the period at issue, Denoma’s major competitors reported declines in revenue that were, in percentage terms, greater than Denoma’s.
C. A significant proportion of Denoma’s revenue comes from making components for other consumer-electronics manufacturers.
D. Unlike some of its major competitors, Denoma has no lines of business outside consumer electronics to provide revenue when retail sales of consumer electronics are weak.
E. During the period, consumer-electronics retailers sold remaining units of Denoma’s superseded models at prices that were deeply discounted from those models’ original prices.

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?
A. Even homeowners whose yards do not have water-conserving landscapes can conserve water by installing water-saving devices in their homes.
B. A conventional landscape generally requires a much greater expenditure on fertilizer and herbicide than does a water-conserving landscape.
C. A significant proportion of the residents of the city live in buildings that do not have yards.
D. It costs no more to put in water-conserving landscaping than it does to put in conventional landscaping.
E. Some homeowners use more water to maintain their yards than they use for all other purposes combined. |
