1.More and more companies have begun to consume less energy by making themselves more efficient. Over time, these efforts could place the United States at the forefront of an emerging global market for cleaner technologies. Such efforts are also essential to tackling the two big energy-related issues of the age: global warming and the dependence on precarious supplies of oil. The federal government should encourage these efforts by providing the necessary incentives, whether as loans, direct grants or targeted tax breaks. Which of the following, if true, provides the most effective support for the argument?
A On the average, Canadian companies are more energy efficient than those in the United States. B Experts believe that energy efficiency could lower the energy use of the United States to the level of 1995. C In the past, government incentives have made advances in energy conservation feasible, especially in the auto industry. D The dependence on foreign oil is a greater problem in the present than global warming. E The market for cleaner technologies is currently relatively small because of the infrastructure requirements.
2. State X recently decided to cut state funding for the public library system in County X. To help counteract this cut in funding, the county library system has increased library late fees from $.10 per day to $.12 per day. Since the fee increase, library administrators have seen no decline in the number of overdue books. The director of the county library system concludes that the fee hike has helped to counteract the cut in state funding. Which of the following statements, if true, most strengthens the director’s claim? A Since the fee increase, library administrators have noted a significant decrease in the number of books borrowed each day. B The library system incurred minor costs to make its visitors aware of the late fee increase. C Since the fee increase, there has been no significant change in the average number of days that books are overdue before they are returned. D The library system in County X tracks its books through a very advanced database system, allowing library administrators to have access to very accurate statistics on the number of overdue books at any given time. E Since the reduction in state funding, the library system in County X has eliminated 10% of its staff, creating a 2% reduction in costs.
