A recent nationwide survey of dementia patients revealed an interesting fact—almost all of the patients surveyed were more than 70 years of age and watched more than six hours of television every day. So, in order to avoid getting afflicted with dementia, people who are more than 70 years of age should not watch more than six hours of television in a day.

Which of the following would be most useful to determine in order to evaluate the argument?

(A) Whether people less than 70 years of age can also get afflicted with dementia

(B) Whether there are some visible symptoms of dementia, thereby making it easier to identify such cases

(C) Whether being afflicted with dementia makes people want to watch more television

(D) Whether regular therapy and medicines can reverse the onset of dementia

(E) Whether there can be some other cause of dementia, apart from watching more than six hours of television every day

The stem observes that dementia and tv-watching are correlated. The stem suggests that tv-watching causes dementia. It's possible that the reverse is true: dementia causes tv-watching. So C is the answer.

Why can't it be E? E suggests that there might be an alternative cause of dementia?

I always keep this handy and also might be helpful to you.
In any case in which X causes Y (X->Y).
A correct evaluate can be "Whether Y causes X?" (because here "Yes / No" ans to this evaluate question strengthens /weakens the conclusion which was : watching TV caused Dementia)

This can also be applies to Strengthen /weaken question

For example Lets consider argument which states : X->Y
A correct strengthener can be :
a): Y does not cause X
Or
b): Y is not caused by any other thing(except X)

Similarly,
A correct Weakener can be
a): Y causes X
Or
b): Y is caused some other factor

So basically this applies here in evaluate question as already explained

Answering your question "Why can't it be E? E suggests that there might be an alternative cause of dementia?"
-> Yes / No answer to this question does not cover entire causality
Lets say "YES There is alternative cause to Dementia" But this does not evaluate whether TV was cause for dementia . It just says that there can be other factors too(which may or may not include TV).
Similarly "NO There is alternative NO cause to Dementia" so what next?? Did this say TV did not cause Dementia? It just said NO ALTERNATIVE.

Hope this helps!
