Rahul,
To distinguish between answers, it is important to pay close attention to the specific words that both the argument and the answer choices use. In this case, the conclusion is
Researchers have concluded that the will to live can prolong life, at least for short periods of time. The only premise (fact) upon which this conclusion rests is that
Studies have shown that elderly people who practice a religion are much more likely to die immediately after an important religious holiday period that immediately before one
The argument at hand concerns only religious people and their death rates around important religious holidays. Thus answer choice A, the better answer, definitely strengthens the conclusion, as it supports the idea that these individuals demonstrate a "will to live" as important religious holidays approach.
To me, answer choice E is too broad and is also too disconnect from the argument. The argument is about death rates of
religious people; answer choice E relates to elderly people in general. Moreover, instead of specifying times during or immediately before or after religious holidays, answer choice E refers to an entire half of the year (2 out of the 4 seasons). Too many other factors could affect death rates during such a broad time frame.
Hope that helps!

Studies have shown that elderly people who practice a religion are much more likely to die immediately after an important religious holiday period that immediately before one. Researchers have concluded that the will to live can prolong life, at least for short periods of time.
Which of the following, if true, would strengthen the researchers' conclusion?
(A) Elderly people who practice a religion are less likely to die immediately before or during an important religious holiday than at any other time of the year.
(E) Many religions have important holidays in the spring and fall, seasons with the lowest death rates for elderly people.
