Question

Quizplus · Accepted Answer

Aerodynamically designed vehicles provide better fuel economy by reducing wind resistance and drag. This has become a major focus for automobile manufacturers in recent years in order to meet stricter fuel efficiency standards.

Answer: B
 This statement is false. Seat belts are now standard equipment in all automobiles and have been proven to save lives in the event of an accident.

Answer: C
 This statement is false. Crumple zones are designed to absorb energy upon impact, reducing the force of the collision on the occupants of the vehicle. They are most effective at lower speeds, typically between 25 and 40 mph.

Answer: D
 This statement is false. Materials used in automobile design have evolved significantly over the years, with an emphasis on using lightweight but strong materials that can improve fuel efficiency and safety. For example, many vehicles now use aluminum instead of steel in certain components.
