Ergonomically designed computer keyboards tend to lose their “play”—the responsiveness of the keys— more quickly than do traditional keyboards. A software designer has suggested that it is in fact the curvature of the key rows and not increased typing speed that is to blame. Due to the bent shape of the board, it is more difficult for the average user to clean between the keys, resulting in a gradual deadening of the spring mechanisms.

The answer to which of the following questions will most likely yield significant information that would help to evaluate the software designer’s hypothesis?

A. Do traditional keyboards and ergonomically designed keyboards utilize the same plastics?

B. Does sprinkling a keyboard with dust impede the spring action beneath the keys?

C. Does a keyboard with deadened play make typing more difficult?

E. Are software designers more likely than other users to utilize their keyboards when working?

The stem gives us two competing hypotheses: keyboards lose their "play" either because people type faster on them (wearing them out I guess), or because they get dirty and that affects "play". Only answer B is remotely relevant to evaluating one of those hypotheses.

There's a problem with the question setup though - the stem states as a premise that not cleaning properly leads to a deadening of the spring mechanisms. But if B is correct, and we need to conduct an experiment to confirm that dirt deadens the springs, it's not a premise. They mean for that claim to be part of the software designer's hypothesis, but it's stated as if it's a fact.
