PrepTest 23, Section 3, Question 9
If a person chooses to walk rather than drive, there is one less vehicle emitting pollution into the air than there would be otherwise. Therefore if people would walk whenever it is feasible for them to do so, then pollution will be greatly reduced.

Which one of the following, if true, most strengthens the argument?
If automobile passengers who never drive walk instead of ride, there will not be fewer vehicles on the road as a result.
Nonmoving running vehicles, on average, emit half as much pollution per second as moving vehicles, but the greater congestion is, the more nonmoving running vehicles there are.
Since different vehicles can pollute at different rates, it is possible for one driver who walks to make a greater contribution to pollution prevention than another driver who walks.
On average, buses pollute more than cars do, but buses usually carry more passengers than cars do.
Those who previously rode as passengers in a vehicle whose driver decides to walk instead of drive might themselves decide to drive.
