Q1. Many companies that sell computer software are trying to increase the productivity of their programmers, measured by the lines of code written in one day by a programmer. One method attempted by some companies is to let programmers work from home. Programmers who work from home do not need to commute to and from work and can therefore spend more of the day writing code. Therefore, companies that allow their programmers to work from home will see a corresponding increase in the productivity of those programmers. Which of the following, if true, most strengthens the argument? A. Before the advent of virtual private network technology, working outside of the office presented security risks unacceptable to most companies. B. Programmers write more effective code when they are able to work in a comfortable environment. C. Companies that allow employees to work from home can see reductions in certain expenses, such as electricity and building upkeep. D. Most older companies oppose allowing employees to work from home, whereas most newer companies support employees working from home. E. The number of lines of code a programmer writes per hour is relatively constant. Difficulty - Hard

Q2. Ninety percent of recent car buyers say safety was an important factor in their purchase. Yet of these car buyers, only half consulted objective sources of vehicle safety information before making their purchase; the others relied on advertisements and promotional materials. Thus, these other buyers were mistaken in saying that safety was important to them. The argument’s conclusion follows logically if which one of the following is assumed? (A) Someone who claims that safety was an important factor in a buying decision does not necessarily mean that safety was the most important factor. (B) Advertisements and promotional materials sometimes provide incomplete vehicle safety information. (C) Recent car buyers do not necessarily tell the truth when asked about the factors that contributed to their vehicle purchases. (D) Most consumers are aware that advertisements and promotional materials are not objective sources of vehicle safety information. (E) Anyone to whom safety is an important factor in purchasing a car will consult an objective source of vehicle safety information before buying. Difficulty - Hard
CR Questions October - 15 :Q1. Delta green ground beetles sometimes remain motionless for hours at a stretch, although they are more active in wet years than in dry years. In 1989 an observer spotted ten delta green ground beetles in nine hours; in 1985 the same observer at the same location had counted 38 in about two hours. This difference probably does not reflect a drop in the population of these rare beetles over this period, however, because 1985 was a wet year and 1989 was relatively dry.
Which one of the following, if true, most strongly supports the conclusion drawn above?
(A) Because of their excellent camouflage, delta green ground beetles are almost impossible to see if they are not moving.
(B) The only habitat of delta green ground beetles is around pools formed by the collection of winter rains in low-lying areas.
(C) Della green ground beetles move about very little to get food; most of their moving from one place to another is related to their reproductive behavior.
(D) Della green ground beetles are so rare that, although the first specimen was found in 1878, a second was not found until 1974.
(E) No predator relies on the delta green ground beetle for a major portion of its food supply.

Q2. Letter to the editor: Your article was unjustified in criticizing environmentalists for claiming that more wolves on Vancouver Island are killed by hunters than are born each year. You stated that this claim was disproven by recent studies that indicate that the total number of wolves on Vancouver Island has remained roughly constant for 20 years. But you failed to account for the fact that, fearing the extinction of this wolf population, environmentalists have been introducing new wolves into the Vancouver Island wolf population for 20 years.
Which one of the following most accurately expresses the conclusion of the argument in the letter to the editor?
(A) Environmentalists have been successfully maintaining the wolf population on Vancouver Island for 20 years.
(B) As many wolves on Vancouver Island are killed by hunters as are born each year.
(C) The population of wolves on Vancouver Island should be maintained by either reducing the number killed by hunters each year or introducing new wolves into the population.
(D) The recent studies indicating that the total number of wolves on Vancouver Island has remained roughly constant for 20 years were flawed.
(E) The stability in the size of the Vancouver Island wolf population does not warrant the article’s criticism of the environmentalists’ claim.
