Take the following as truth: Modeling shows that when full implementation of existing regulations such as the acid rain program, the NOx SIP Call, the Tier II standards for cars and trucks, the heavy duty diesel engine standards, and the low sulfur gasoline and diesel fuel rules are taken into account, additional reductions will be needed to bring areas into attainment.
Then the following statement: "The acid rain program entails regulations for acid and rain." is true, false, or inconclusive?
Answer: Inconclusive
