Option 5: the questioner is optimizing a metric other than what appears to be the post’s implicit “get max info with minimal number of questions, ignoring communication overhead”, which is IMHO a weird metric to optimize to begin with—not only it does not take length/complexity of each question into account, but is also ignoring things like maintaining answerer wilingness to continue answering questions, not annoying the answerer, ensuring proper context so that a question is not misunderstood, and this is not even taking into account the possiblity that while the questioner does care about getting the information, they might also simultaneously care about other things.
