(9) Roads are salted in order to

	(a) kill grass.
	(b) melt snow.
	(c) help the economy.
	(d) prevent potholes.

The correct answer is (c). Road salting employs thousands of persons
directly, and millions more indirectly, for example, salt miners and
rustproofers.  Most important, salting reduces the life spans of cars,
thus stimulating the car and steel industries.
