The correct answers are Do humans usually drink this hot bean water? and Are you going to add milk to my cup?

Yes/No questions in English usually start with an auxiliary verb (like do, does, is, or are) followed by the subject and the main verb.

• We use do (not does) with plural subjects like "humans."

• We use are (not is) with the pronoun "you."

• Verbs like "drink" cannot simply jump to the front of the sentence; they need the helper verb "do."
