Now am lost, I thought what is 2 words o que, now it is just one word que??
No translation given?
Is it "What milk do you drink?" = "Which one of these glasses of milk belongs to you?"
(If I report it as a problem, I won't find out the answer!)
It probably means "what kind of milk do you drink?" (Leite em pó, tipo A, desnatado, etc.).
