People who do regular volunteer work tend to live longer, on average, than people who do not. It has been found that ‘doing good,’ a category that certainly includes volunteer work, releases endorphins, the brain's natural opiates, which induce in people a feeling of well-being. Clearly, there is a connection: Regular releases of endorphins must in some way help to extend people's lives.
Which of the following, it true most seriously undermine the force of the evidence given as support the hypothesis that endorphins promote longevity
(A) People who do regular volunteer work are only somewhat more likely than others to characterize the work they do for a living as "doing good."
(B) Although extremely high levels of endorphins could be harmful to health, such levels are never reached as a result of the natural release of endorphins.
(C) There are many people who have done some volunteer work but who do not do such work regularly.
(D) People tend not to become involved in regular volunteer work unless they are healthy and energetic to begin with.
(E) Releases of endorphins are responsible for the sense of well-being experienced by many long-distance runners while running.

In all CR questions there is only one common fundamental!! Just read the passage n get to root in a structure like author is saying Y because X...sure there will a lot of background and even side information but there will be a core set of premise supporting author's veiw...once you figure it out your all job almost done!!! after that we need to find gap along authors reasoning...there will be a lot of answers choices that will strengthen or weaken the argument but that will not be in line of reasoning presented in arguement...so watch out ...
Now coming to this question...
Authors says
Endorphins promote longevity because
Studies shows people who volunteer lived longer because during regular volunteering endorphins released!!!
Note: getting gist is an art
You will get better by practicing and analyzing...but I answer all questions this way ...
So Gap is quite obvious!!!
1)He assumed it was endorphins that caused them live longer!! In volunteering regularly not any other factors that might come when you regularly volunteer
2) He assumed it was because of volunteering not because of any other factors than this...
And this is very normal structure where author assumes it was only this X which caused Y ...just because Y and X happened doesn't mean they have to be correlated!!!
So weakner would be any options that says it was endorphins and indeed some other factors that led them live longer...
A) it's not because they will characterize some good work bad then it's bad.. whatever they characterize endorphins will release anyway..so it does not let you assume that okay they didn't characterize it as good work as such so no endorphins n there have been other factors!! Its almost challenging premise too...its written volunteering is categorized Good and endorphins release in that
B) irrelevant!! Its not about endorphins levels !! Its about he whether endorphins caused it or not!! For an instance word natural release might hit many of us..okay endorphins releases naturally so its same in those who dont do volunteering..but still that didn't make us prove that this didn't cause them to live longer
C) it's about regular volunteering ppl not irregular one..out of scope
D) correct as it is saying ppl were already healthy and fit who started volunteering so it's not endorphins rather their initial state made them get into volunteering..so health caused endorphins release in a way you can say ..opposite of what author assumes
Just here few ppl might have doubts like ppl having health and energetic doesn't mean they live longer..true but we need to assume slight things..cuz GMAT cant give all straight for strenghthener weakner..after all they just add support ..dont make it solid..like assumptions only questions
E) Endorphins are responsible for something in runners..do how does it make us believe okay this will be applicable for volunteering men too..
