PrepTest 22, Section 2, Question 14
Charles: During recessions unemployment typically rises. Thus, during a recession air pollution due to automobile exhaust decreases, since fewer people commute in cars to jobs and so cars emitting pollutants into the air are used less.

Darla: Why think that air pollution would decrease? During a recession fewer people can afford to buy new cars, and cars tend to emit more pollutants as they get older.

Which one of the following is an assumption on which Charles's argument depends?
People who have never been employed drive no less frequently during a recession than they would otherwise.
Most air pollution is caused by automobile exhaust emitted by cars used by people commuting to jobs.
Most people who are employed do not use any form of public transportation to commute to their jobs.
During a recession, decreases in the use of cars resulting from reductions in commuting to jobs are not offset by increased use of cars for other reasons.
During a recession, a higher proportion of people who commute in cars to their jobs lose those jobs than do people who do not use cars to commute to their jobs.
