What is the difference between these two sentences, if there is one?
"What is inside the box?" and "What is there inside the box?"
A native speaker once told me they are the same, but the former is grammatically more correct. But I've come across the latter in some grammar books.
To clarify my question, I'd like to put it this way: What is are the best questions for these statments? "There is a toy in the box" and "The toy is in the box"? I was thinking they would be: "What is there inside the box? -There is a toy in the box." and "What is inside the box? -The toy is inside the box."
