Wearing either a lap seat belt or a shoulder-and-Iap seat belt protects passengers from the major types of injuries incurred in head-on automobile collisions. In such collisions, however, passengers wearing lap seat belts alone frequently suffer internal injuries caused by the seat belt itself. Such injuries do not occur when shoulder-and-Iap seat belts are worn.

Which of the following conclusions about passengers involved in head-on automobile collisions is best supported by the statements above?

(A) No type of seat belt provides passengers with adequate protection from injury.
(B) The injuries that passengers most frequently incur are internal injuries.
(C) Head-on automobile collisions cause more injuries to passengers than any other kind of automobile accident does.
(D) It is safer for passengers to wear a shoulder-and-lap seat belt than to wear a lap seat belt alone.
(E) It is safer for passengers to wear no seat belt than to wear a lap seat belt alone.

(A) The term "adequate" is subjective, and we aren't given any measure for it in the statements. So we don't know what is adequate and what isn't.

(B) We are also not told what kind of injuries are incurred. We might say that passengers wearing lap seat belts alone incur internal injuries, but this leaves out the entire category of passengers wearing shoulder-and-lap belts.

(C) We don't have any reason to say this either. Maybe rear end collisions cause many more injuries that cannot be prevented by seat belts, so the statements don't deal with them.

(D) Yes. Wearing either kind of belt will prevent injuries from the accident, but wearing a lap belt alone will cause other injuries. The should-and-lap belt causes no injuries. So you'll have less injuries if you wear the shoulder-and-lap belt.

(E) We can't conclude this either. Wearing no seatbelt will prevent the internal injuries caused by lap belts alone, but this is quite minor compared with the perils of flying through the windshield.
