"Does she not drink milk?"
Translation:Drinkt ze geen melk?
"Does she not" sounds really old-fashioned. The modern equivalent is "Doesn't she". I understand some courses deliberately avoid English contractions, and I believe this is doing a disservice to English learners.
Contractions are handled by an algorithm, hence they are out of our control and for any complaints you should submit a bug report.
Really? That certainly is not true. It would be hard to believe a book would be published containing a mistake like that. (And in an online version of the book, it definitely did not have that statement).
If the question is referring to "you" (je/jij) use drink. Otherwise, use drinkt
Because it's ungrammatical.
If you're asking about the negation of the fact that she drinks in general (even water... I don't know, because she's in a coma, and therefore she doesn't drink, since she's getting her fluid intake through an IV), then you could say Drink ze niet?
Otherwise, if you're asking about the fact that she doesn't drink milk (which is then a specific 'instance of drinking', since she drinks water, juice, tea, coffee, etc., but not milk, so you ask as to check your hypothesis regarding the possibility that she's on a vegan diet), then you'd say Drinkt ze geen melk?
So, in a way, you could 'see' this whole thing of 'negating the verb/an action' (general, so we use niet), or 'negating a noun/the object of a verb' (specific, narrowing down the scope of the action to a specific instance of it, so we use geen). Note that geen must always be placed before the object (be it concrete or abstract) it negates, since it's a determiner.

Is it any clearer?
Hope this helps.
Het is wel juist. De ik-vorm geldt alleen wanneer het werkwoord voor het onderwerp staat en het onderwerp je/jij is.
It is correct. You only use the stem of the verb if the verb preceds the subject and the subject is je/jij.
