Where do you think, we are in?
What's wrong with this sentence? My editor says the following comment.
Review this sentence for preposition use, particularly at the end of sentences The preposition, “in”, is at the end of a sentence. Consider re-wording your sentence so the preposition is not at the end. In informal cases, we often end a sentence with a preposition. When writing formally, ending a sentence with a preposition should be avoided. Prepositions are words like on, in, to, with, from, about and through.
