Electricity accounts for almost 20% of the cost of making steel. A 10% increase in electricity prices results in steel firms decreasing production and thereby demanding 5% less electricity. Over many years, technological innovations can change the way steel firms make steel and reduce the industry's energy requirements. This suggests that the steel industry's long-run elasticity of demand for electricity is probably

	A.	same as its short-run elasticity of demand for electricity.
	B.	There is not enough information.
	C.	more than its short-run elasticity of demand for electricity.
	D.	less than its short-run elasticity of demand for electricity.
