Which of the following would not be a way we can cut back on our use of oil?
a. moving your family farther away from where you work
b. better insulating our homes and windows
c. using less air conditioning in the summers
d. using cars that are more fuel efficient

The answer is A. Because all the remaining answers are good examples of how people could generally cut back on their use of oil. And if your family moves father away from where you work, you will need to travel longer distances, and thus use more oil, which is opposite of what you are trying to do.
