Similar question but not extremely useful because this time is about multi-question puzzles rather than the answers quality.
I recently posted this puzzle which was composed of multiple questions of the form: can you do [something] for $n=6$? And for $n=8$? For which value of $n$ [the same thing] can be done? Which is the best way to do it? I thought it was fine to include all these questions on the same post because they were highly correlated.
However I received 5 answers (which I think is a lot): the quickest users just answered the first few questions because it was a relatively simple problem. Then someone else answered the last non-obvious question without answering the first question because "an answer was already posted" (I agree with them on this point).
How do I choose the answer to accept if there are a few satisfactory answers but none of them answers all the questions in the original post?
