"Is this a fish or a mug?"
Translation:Đây là một con cá hay là một cái ca?
Presumably, if the person addressed knows what "this" refers to, he also knows whether "this" is one or more items. Hence, the question. "Một" makes things clear in this isolated sentence, but I still wonder whether it would always be used in a conversational context where it is logically redundant.
I put: Đây là một cá hay một ca?
This was marked as incorrect. Can someone explain to me when we would use the classifier? I though that since we are saying "một" for one or a, we would not need con or cái? Isn't this like saying "Is this a the fish or a the mug"? Can someone clarify this? Thanks!
