The answer, lsacgals101, is (I'm sorry to do this to you) both. You've come across the troubling case of a "nested conditional", which is a conditional statement that has another conditional statement "inside" it, either as a sufficient condition or as a necessary condition or both. Your first diagram, with everything "crammed in" as you said (and that is an excellent way to describe a nested conditional!), captures exactly that situation - conditional statements that are within a larger conditional statement.
But you can also take a simpler approach as you did in your second diagram, and try to link them in some way, thereby creating the nested conditional relationship. Many times I find that approach to be a bit cleaner, at least to understand and break down the answer or the stimulus, but then it is a little extra work to make the link.
Ultimately, I think the best approach starts, as it always does, with a solid prephrase. We should be looking for an answer that says something along the lines of "if a lot of people need to do something for it to work, then each person who wants it done should do it." Find an answer that connects the ideas of "many people need to do it" to the conclusion that "one person should do it." I think that would allow a more holistic approach to the answers, rather than one that relies on diagrams that can, as you found, slow you down. You should not be diagramming any answers until you have first sorted them into losers and contenders based on the degree to which they match your prephrase, and then, if you must, diagram only your contenders to see which one gets it right. Diagramming them all as you go is slow and inefficient, and should not be necessary if you are armed with a good prephrase.
