Oil is a nonrenewable resource, whereas sunshine is limitless. So why not run cars on solar power? Because a car powered by solar collecting panels would be fine on a sunny day, but as soon as the sun went behind a cloud, the car would no longer function.
Which of the following is presupposed in the argument against running a car on solar power?
A. Solar power is cleaner than fossil fuels, and it involves less geopolitical risk.
B. In most of the northern hemisphere, it can be expected that more than 150 days a year will be cloudy.
C. No system exists for storing solar energy for a car’s use when the car is not in direct sunlight.
D. No one has yet introduced a commercially viable process for massproducing solar cells that convert more than 10 percent of incoming sunlight into usable energy.
E. Consumers accustomed to the rapid acceleration of gasoline-powered cars will not accept the weak acceleration of solarpowered cars.
