"Where are the glasses?"
Translation:안경이 어디에 있어요?
What is the difference between 안경은 어디에 있습니다? (which is marked incorrect) and 안경이 어디에 있어요? (which is marked correct)? The only difference I can see is the formality of the first. At my level of understanding, they both appear to be grammatically proper. Or is the difference the "the" in the translation provided, if it corresponded better to the subject particle than the topical particle?
