Question

post-test
plastics used in vehicle construction can:
a. use more fuel.
b. increase fuel mileage.
c. be derived from natural resources.
d. increase vehicle weight.

Explanation:

Plastics are lightweight materials. Using them in vehicle construction reduces vehicle weight. A lighter vehicle requires less fuel to move, so it increases fuel mileage. Option A is incorrect as lighter weight means less fuel use. Option C: while some plastics can be derived from natural resources, the primary benefit in vehicle construction related to performance (fuel mileage) is due to weight reduction. Option D is incorrect as plastics reduce weight. So the correct option is B.

Answer:

B. Increase fuel mileage.
