US Highway 12 Is Part of a Crucial Two-Lane Artery

Multiple Choice

U.S. Highway 12 is part of a crucial two-lane artery from the seaports in Washington State to the tar sands in Canada. Extracting oil from the tar sands requires very large equipment and transporting it takes up both lanes of U.S. Highway12.

If permits for this highway were not allowed, how would that affect the elasticity of which curve in the market for oil?

A) The supply curve would become more elastic.
B) The supply curve would become less elastic.
C) The demand curve would become more elastic.
