Why do humans drink hot bean water every morning? My human subject, Bob, does not like waking up early at all. In fact, yesterday he did absolutely nothing all day!
do: "Every morning" indicates a present habit. "Humans" is plural (they), so we use the auxiliary verb "do" to form the question.
does: Bob is a single person (he), so we use "does" to form a present tense negative sentence ("does not").
did: "Yesterday" tells us this happened in the past. The past form of "do" is "did", used here as the main verb.
