Studies of workplace safety in construction and manufacturing firms have found that the rate of injuries tends to rise when the firms' work loads increase. Since inexperienced workers are often hired by these firms when work loads increase, the higher rate of injuries is undoubtedly due to a higher accident rate for inexperienced workers.

Which of the following statements, if true, would most weaken the conclusion drawn above?

(A) Many of the inexperienced workers hired when the firms' work loads increase are hired only for temporary positions.
(B) The studies of workplace safety were focused only on injuries that resulted in lost workdays.
(C) There is a much higher rate of injury in construction firms than in manufacturing firms.
(D) The accident rate for experienced workers tends to increase whenever the firms' work loads increase.
(E) Firms that hire inexperienced workers for potentially dangerous jobs are required to provide them with training

(A) The timeframe of the argument is only temporary (when workloads increase) anyways.

(B) The conclusion does not distinguish between serious and non-serious injuries.

(C) Since these are lumped together in the conclusion, it doesn't matter which kind of firm is more dangerous.

(D) Here's a good answer. If the experienced workers also get hurt more in busy times, then the higher injury rate is not only due to the inexperienced workers, as the conclusion claims.

(E) Inexperienced workers with training are still inexperienced workers, and might still be injured more often.
