This is a rare, but still recurring, example of a Main Conclusion question in which LSAT is testing the implied conclusion (not an explicitly stated one).
Suppose the argument said:
Should Howie apply to Harvard? He should only if his GPA is over 2.0. However, his GPA is but a 1.5
Were any of these statements the conclusion? No. The first sentence is a question. The second is an unsupported conditional rule. The third is an unsupported statistical fact.
What we mean by "unsupported" is that there's no reason given for believing the 2nd or 3rd sentence.
Howie should apply to Harvard only if his GPA is over 2.0
Why?
[I dunno, the argument never told me. Not a conclusion.]
Howie's GPA is 1.5
Why?
[I dunno, the argument never told me. Not a conclusion.]
What is the reasonable conclusion to extract from the above argument?
Howie should not apply to Harvard.
Why?
He's got a 1.5 GPA and you should only apply to Harvard if you have at least a 2.0 GPA.
This is an implied conclusion.
There is no explicitly stated conclusion in Q14. Let's examine some of the previous contenders for the conclusion and ask ourselves if they were supported or not:
Conc contender 1:
"an act or omission by one person is not right if such an act or omission done by large numbers of people would be socially damaging."
Why? ... well, we could say
Society would be impossible with mass theft, even if a single act of dishonesty would have negligible harm.
I think that this "premise" is more an illustration of the general principle than it is a reason why we should accept the principle. But more importantly, if this were our conclusion/premise, then what the heck was all that discussion of voting good for? Whatever we decide is the main conclusion shouldn't leave other parts out in the cold. It should be the umbrella claim under which all other claims in the argument have some purpose.
Conc contender 2:
"but one must consider the likely effects of large numbers of people failing to vote."
Why?
An act isn't right for individuals if it wouldn't be right for large numbers of people.
+
Illustration of that principle (theft/dishonesty example)
This one seems closer and could probably be considered a subsidiary conclusion. It does tie in the original subject matter of voting, but it leaves the first sentence of the argument out in the cold.
If we revisit the correct answer (A):
"People in a democracy should not neglect to vote:
Why?
If they don't vote, democratic institutions crumble and social cohesion is lost.
+
Even though one person's vote is negligible, you have to consider mass scales of non-voting
why?
Individuals acting a certain way is wrong if lots of people acting that way would be wrong.
+
Illustration (theft/dishonesty)
====
Ultimately, I think people are fine with accepting that (A) expresses the gist of what the paragraph was talking about.
The issue people have with this problem (and others with implied conclusions) is that there is no longer a claim in the argument we can actually bracket off as our conclusion.
Hopefully, now that you know that implied conclusions are fair game, you'll have the flexibility to consider such a thing if there doesn't seem to be any explicit conclusion.
===other answers
(B) has the extreme and unjustified comparison "equally damaging"
(C) leaves voting unmentioned, when it is the launching point and focus of this whole discussion
(D) contradicts the argument, which said that "one person's vote can only make an imperceptible difference"
(E) does not deal with the main topic of voting, puts undue emphasis on dishonesty / neglect of duty, and makes a prediction about democratic and OTHER societies.
Let me know if you have any more questions.
