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 one of the following, if true, would constitute the strongest objection to the executive's argument? ['New computerized fuel systems can enable large cars to meet fuel efficiency standards established by the recent guidelines.', 'Fuel efficiency in models of large cars rose immediately after 1977 but has been declining ever since.', 'Modern technology can make small cars more fuel-efficient today than at any other time in their production history.', 'Even after 1977, large automobiles were frequently involved in accidents that caused death or serious injury.']
