In 1996, the World Trade Organization (WTO) ruled that the U. S. Environmental Protection Agency (EPA) regulation calling for cleaner gasoline
discriminated against foreign producers and violated WTO agreements. The
EPA was forced to rewrite the rule to allow for dirtier gasoline. What effect did
this revision likely have on world trade?
O A. The revision probably increased world trade because gasoline that
previously couldn't be sold in the United States was made to meet
a higher environmental standard.
O B. The revision probably increased world trade because gasoline that
previously couldn't be sold in the United States was then allowed
to be sold there.
O C. The revision probably decreased world trade because gasoline
that previously couldn't be sold in the United States had to be sold
in other countries.
O D. The revision probably decreased world trade because gasoline
that previously couldn't be sold in the United States was then
allowed to be sold there.
