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.
