Grammar Builder Exercise – Critical Reasoning Challenges

Question 1: Which of the following would, if true, most strongly suggest that the plan, if implemented, would increase the overall efficiency of PhishCo’s farms?

PhishCo runs a number of farms in the arid province of Nufa, depending largely on irrigation. Now, as part of a plan to efficiently increase the farms’ total production, it plans to drill down to an aquifer containing warm, slightly salty water that will be used to raise fish in ponds. The water from the ponds will later be used to supplement piped-in irrigation water for PhishCo’s vegetable fields, and the ponds and accompanying vegetation should help reduce the heat in the area of the farms.

(A) Most of the vegetation to be placed around the ponds is native to Nufa.

(B) Fish raised on PhishCo’s farms are likely to be saleable in the nearest urban areas.

(C) Organic waste from fish in the pond water will help to fertilize fields where it is used for irrigation.

(D) The government of Nufa will help to arrange loan financing to partially cover the costs of drilling.

(E) Ponds will be located on low-lying land now partially occupied by grain crops.

Question 2: Which of the following, if true, most logically completes the argument below?

Manufacturers are now required to make all cigarette lighters child-resistant by equipping them with safety levers. But this change is unlikely to result in a significant reduction in the number of fires caused by children playing with lighters, because children given the opportunity can figure out how to work the safety levers and ……………….. .

(A) the addition of the safety levers has made lighters more expensive than they were before the requirement was instituted

(B) adults are more likely to leave child-resistant lighters than non-child-resistant lighters in places that are accessible to children

(C) many of the fires started by young children are quickly detected and extinguished by their parents

(D) unlike child-resistant lighters, lighters that are not child-resistant can be operated by children as young as two years old

(E) approximately 5,000 fires per year have been attributed to children playing with lighters before the safety levers were required

Question 3: Which of the following, if true, would provide the greatest additional support for the editorial’s conclusion?

Editorial: Consumers in North America think that by drinking frozen concentrated orange juice, they are saving energy, because it takes fewer truckloads to transport it than it takes to transport an equivalent amount of not-from-concentrate juice. But they are mistaken, for the amount of energy required to concentrate the juice is far greater than the energy difference in the juices’ transport.

(A) Freezer trucks use substantially more energy per mile driven than do any other types of trucks.

(B) Frozen juice can be stored for several years, while not-from-concentrate juice lasts a much shorter time.

(C) Oranges grown in Brazil make up an increasing percentage of the fruit used in not-from-concentrate juice production.

(D) A serving of not-from-concentrate juice takes up to six times more space than a serving of frozen concentrated juice.

(E) Though frozen concentrated juice must be kept at a lower temperature, not-from-concentrate juice is far more sensitive to small temperature fluctuations.
