Skynet, a technology marketing firm proposes the use

Question

Skynet, a technology marketing firm proposes the use of "high-frequency sensors" in computers to monitor people's computer usage habits. These high-frequency monitors, which are embedded in the computer's screen, can send out low-level ultraviolet waves that help determine changes in mood and alterations in vital signs by measuring sub-cuticle changes in chemical composition of the computer user's body. Some critics fear adverse health effects of such a monitoring system, but a proponent responded that the average dose of radiation would be less than that of one CT scan and that the computer users would not feel anything.

Which of the following issues would it be most important to resolve in evaluating the dispute concerning the health effects of the proposed system?

A.Whether the user will be aware of the fact that his behaviour is being observed
B.Whether the proposed system has been tried out in various areas of the country or in a single area only
C.What uses are foreseen for the computer user data
D.Whether the average dose that the proponent describes is a short-term dose or a lifetime cumulative dose
E.Whether the proposed method of monitoring users can distinguish between people working and people using the computer for games and entertainment

Clearly D. A person does not get CT scanned every day unlike the person using computer almost everyday. If the harmful effects of radiations disappear well before the person uses the computer again the next day, then the proponent can be justified. Else, if the effects are cumulative or add up after usage of each day, then the opponent wins.
Other answer choices are plainly out of scope in terms of health effects.

Solving by thinking Precisely about the information given:   the health dispute, which we are asked about, centers on the size of an average dose of radiation - but how often is this amount applied - if it's everyday, the comparison to a CAT scan is irrelevant, since that's something you only get once or twice. Looking at the answers,  this is what (D) asks.

Solving by Using the Answers:

A.Whether the user will be aware of the fact that his behaviour is being observed  This may be an important question in general, but notice we were asked about the dispute regarding  health effects  only 
B.Whether the proposed system has been tried out in various areas of the country or in a single area only  Not clear why this is relevant  
C.What uses are foreseen for the computer user data  not releveant to the health dispute  
D.Whether the average dose that the proponent describes is a short-term dose or a lifetime cumulative dose  This is directly relevant to the health dispute: if it's a long term dose, the proponent's claim is strengthened, if it's a short-term, it's weakened 
E.Whether the proposed method of monitoring users can distinguish between people working and people using the computer for games and entertainment  Not clear why this is relevant
