Translation:Mamá no nos compra unos celulares.
If they don't put the word "any" in the sentence, how are we supposed to know that's what they mean?? This sentence is a poor example.
Poor example yes but if they put any in the correct answer would be mamá no nos compra ningunos celulares
Do we definitely need that "unos"? Would the sentence be correct like this: "mamá no nos compra celulares"?
Why is no "a" associated with mamá in this? In earlier lessons, it was mentioned that "a" is required for direct reference to a person.
Only when the person is the object of the sentence not when they are the subject.
