    Which of tlre following conclusions can be drawn from these statements?

    (A) Passenger sedans do not usually have stochastic fuel injection.(B) Stochastic fuel injection is found only in high-powered racing cars.(C) Car manufacturers do not include stochastic fuel injection in passenger cars because they fear accidents.(D) Purchasers of passenger cars do not normally purchase stochastic fuel injection because it is expensive.(E) Some passenger sedans are high-powered racing vel'ricles.

    Efficiency experts will attempt to improve the productivity of an office by analyzingproduction produces intodiscrete work tasks. They then study the organization of those tasks and advise managers on techniques to speedproduction, such as rescheduling of employee breaks or relocating various equipment such as the copyingmachines. I have found a way to accornplish increases in efficiency with much less to do. Office workers growincreasingly productive as the temperature drops, so long as it does not fall below 68o F.

    Tlre passage leads most naturally to which of the following conclusions?

    (A) Some efficiency gains will be short-term only.(B) To maintain peak efficiency, an office manager must occasionally restructure office tasks.(C) Ernployees are most efficient when the temperature is at 68oF.(D) The temperature-efficiency formula is applicable to all kinds of work.(E) Office workers will be equally efficient at 67 " F and 69 o F.

    INFERENCE 2.1-10 ques tions/ 12'I . Students need to spend more time studying for standardized tests which colleges use in selection of students. With that

    test preparation scores could be raised and colleges would be likely to admit the students who apply. Such investment ofstudy. tirne could result in an improved student body at colleges and universities.

    Which of the following conclusions can most properly be drawn from the information above?(A) lncreased study time could benefit both the students and the institutions of higher education.(B) Increased enrollments in colleges and universities is likely to be accompanied by the creation of more jobs on

    campuses across the nation.(C) Colleges and universities will decrease their enrollments unless students indicate that they are better prepared.(D) The low test scores have been a cause of economic recession.(E) Low test scores lrave caused a decline in education quality at colleges and universities across the nation.

To prevent some conflicts of interest, Congress could prohibit high-level government officials from acceptingpositions as lobbyists for three years after iuch officiais leave government service. One such official concluded,iro*"u"r, that such a prohibition would be unfortunate because it would prevent high level government officialsfrom earning a livelihood for three years.

    'The official's conclusion logically depends on which of the following assumptions?

    (A) Laws should not restrict the behavior of foflner government officials.1e) mbbyists are typically people who have previously been high-level government officials.iCi t-o*-i"uel government omiiats do not often become lobbyists when they leave government service.(Oj Higt-,-t"uel-government officials who leave government service are capabie cf eaming a livelihood only as

    for only three years.

If the airspace around centrally located airports were restricted to ccmmercial airliners and only those privateplanes equipped with radar, most of the private-plane traffic would be forced to use outlying airfields.

    The conclusion drawn in the first sentence depends on which of the following assumptions?

    (A) Outlying airfields would be as convenient as centrally located airports for most pilots of private planes.(B) Irlost outlying airfields are not equipped to handle commercial-airline traffic.(C) i'iusi private planes that use centrally located airports are noi equipped with radar.in; Con-r*"rcial iirliners are at greater risk of becoming involveC in midair collisions than are private planes.igj A reduction in the risk of midair collision would eventually lead to increases in commercial-airline traffic.
