ELSAT SET 4-Section 1 -10, Section 3 - 8
Why it is C?
10. Auto industry executive: Statistics show that cars that were built smaller after 1977 to make them more fuel-efficient had a higher incidence of accident-related fatalities than did their earlier larger counterparts. For this reason we oppose recent guidelines that would require us to produce cars with higher fuel efficiency.
Which of the following, if true, would constitute the strongest objection to the executive's argument?
(A) Even after 1977, large automobiles were frequently involved in accidents that caused death or serious injury.
(B) Although fatalities in accidents involving small cars have increased since 1977, the number of accidents has decreased.
(C) New computerized fuel systems can enable large cars to meet fuel efficiency standards established by the recent guidelines.
(D) Modern technology can make small cars more fuel-efficient today than at any other time in their production history.
(E) Fuel efficiency in models of large cars rose immediately after 1977 but has been declining ever since.
Why it is C, not E?
8. Older United States automobiles have been identified as contributing disproportionately to global air pollution. The requirement in many jurisdictions that automobiles pass emission-control inspections has had the effect of taking many such automobiles out of service in the United States. As they fail inspection and their owners opt to buy newer automobiles. Thus the burden of pollution such older United States automobiles contribute to the global atmosphere will be gradually reduced over the next decade.
Which one of the following, If true. Most seriously weakens the argument?
(A) It is impossible to separate the air of one country or jurisdiction from that of others.
(B) When automobiles that are now new become older, they will, because of a design change. Cause less air pollution than older automobiles do now.
(C) There is a thriving market for used older Untied States automobiles that are exported to regions that have no emission-control regulations.
(D) The number of jurisdictions in the United States requiring automobiles to pass emission-control inspections is no longer increasing.
(E) Even if all the older automobiles in the United States were retired from service. Air pollution from United States automobiles could still increase if the total number of automobiles in use should increase significantly.
