which to use?

[ONI]

Dear teachers,

I would like to know which to choose to be the relative clause. For example, The car knocked the child down. It did not stop. The answer key is: The car which knocked the child down did not stop. I remember there is a rule for this, but I forget. Can you tell me to sort out the solution? Thank you very much!

The relative clause in “The car which knocked the child down did not stop.” is “which knocked the child down.” The signal is the relative pronoun ‘which’.

Thank you! Can the combined sentence be: The car which did not stop knocked the child down?
