Thanks for the question, Emily. Since the goal throughout this test is to always pick the best answer (which may not be perfect, and may not even be good), rejecting answers as losers is just as important, and maybe more important, than deciding on the correct answer in a given situation. For that reason, let's start by talking about why A is wrong.
Main Point questions in RC need to be comprehensive - they need to cover the whole scope of what the passage was all about - and they need to limit themselves to that scope and go no further. Narrow answers, answers that only address a portion of the passage or a minor point, should therefore be rejected as losers. So should answers that are too broad, that overstate what the passage had to offer.
Answer A fails for both of those reasons - it deals with an issue that was a minor point of the passage, and it was too broad. The minor point is that people do not always make decisions that are based on purely rational economic self-interest. While true, that statement hardly conveys the bigger issues in the passage, that evolutionary processes apparently led to these irrational decisions in limited situations. It's also too broad, because it overstates the claim about not being rational. It puts it in absolute terms - people DON'T act rationally - instead of limiting the scope the way the passage did, to people don't ALWAYS act rationally.
For these reasons, A has to go - it's a loser. You apparently decided, correctly, that C, D and E were also losers, which should have left you with only answer B still standing. While you weren't in love with the term "predisposition", you didn't reject it because that word was wrong, but because you weren't certain about it, right? Maybe you didn't like it because it wasn't a predisposition until millions of years of shaping had taken place? But uncertainty, even a touch of dislike, is not enough to make an answer a loser. The problem should be something you can articulate, a flaw that you can describe clearly, before you reject it. At this point, with one answer standing and no solid argument against it, you should pick it and move on. That's the whole essence of the losers/contenders approach - don't get hung up on analyzing an answer too much or looking for one that's perfect or even good. Just reject the four worst answers and pick the one that's better than those.
That said, answer B is actually a really good answer. The idea of "predisposition" is well supported by the claim in the passage that "we instinctively feel the need to reject dismal offers". Instinct and predisposition are close enough for the LSAT! They are probably close enough for almost any other situation, too.
Think on that losers/contenders approach some and see if it doesn't make sense. If I have totally missed the boat about why you rejected B and picked A, let me know and I'll try again!
