Answer 1

Answer:

The correct sentence is "As I walked into the room, there she was." There means "in that place."

The words there, their, and they're can be tricky to use because they are all pronounced the same way but they all mean something very different.

There means "in that place," "at that location," or "to or into that place" and is used to talk about the location of something. You can remember that there has to do with location because it has the word here in it. Below are some examples of how it is used.

I left my keys over there, on the table.

When you went to her house was she there?

I can't wait to get there--we've been in this car for hours.
