Question

A series of federal regulations requiring changes to the oil refinement process took effect in the 1990s. Which of the following U.S. states was least affected by the policies? California Texas Mississippi Florida

Answer 1

The United States state that was the least affected by these new policies was "Florida," since Florida's oil exports and production during this time were slight compared to the other states in question. 

Answer 2

The federal regulations that took place during the 1990s focused on pollution control and abatement costs, these regulations had a big impact in Texas, California and Mississippi because of their big oil and gas industry. On the opposite hand, Florida doesn't have any oil refinery which is why it was the least affected.
