I just did this problem and had the same question - I thought answer (B) saying it is to the advantage of some individuals to be concerned about society went too far (I thought the correct way to phrase it would have been it is either neutral for them OR to their advantage). This type of reasoning would imply the right answer in (B)-like format is something like this: "It is not to the disadvantage of some individuals that they be concerned with contributing to societal good". But I still have a problem with even this answer, because the passage talks about what happens if you are unconcerned only, and doesn't make any statement about what happens if you are concerned. We have no idea what advantage/disadvantage you might have if you are concerned. For me the clearest answer would have been : "Being unconcerned about contributing to society can damage yourself and society are large".
Honestly I still am not satisfied that (B) is a necessary assumption, but the best I have done so far is come up with a very weak rationale for (B). If we take the last sentence about modern literature damaging individuals who have an unconcerned attitude as meaning that there definitely are individuals who currently have an unconcerned attitude and are currently disadvantaged, then we can say definitively that there is an assumption that these people would be at an advantage if they were to start being concerned with contributing to societal good. So far this is the best analysis I have for making sense of (B). But it is very weak because it requires an assumption itself - that individuals have actually appropriated the unconcerned attitude as mentioned in the last sentence (it could be no nobody has this attitude).
Any other interpretations?
EDIT:
I think I've answered my own question, after thinking more about what the first person to respond had said. The mistake I made is this: normally when I think of the opposite of something, like the opposite of "black", I think "not black", which means any number of colors. But in this situation, the opposite of "concerned" is "not concerned", which IS unconcerned - this means there are only two states: being concerned and being unconcerned. The logic is: if you are not unconcerned, then you are concerned. And if you are not concerned, then you are unconcerned. Not being one NECESSITATES that you are the other. That means you MUST be either concerned or unconcerned. And since being unconcerned makes you "disadvantaged", you MUST always be at a relative disadvantage/advantage. Because if you unconcerned, you are necessarily disadvantaged. But if you are NOT unconcerned, then you are necessarily concerned. And if you are concerned, you do not have that disadvantage, which means you have a relative advantage.
It is difficult for me to put this into formal logic, but here is my best try:
we start out with the obvious assumption:
Unconcerned --> disadvantaged (damaged is disadvantaged)
contrapositive is : not disadvantaged --> not unconcerned
as described above, due to the binary nature of this situation, (where ~X necessitates X) we know that :
not unconcerned --> concerned
not disadvantaged --> advantaged
putting it together:
advantaged --> concerned
Therefore, it is to the advantage of some individuals to be concerned, because being concerned is necessary if you want to have an advantage.
