To make this a pronoun case the orginal sentence is Pedro Martinez signed a baseball for Chad that he had used in a game.
correction would be Pedro Martinez signed a baseball for Chad that he had previsouly used in another game.
Please enter the "before" and "after" sentences on separate lines. Please also make the directions a bit more clear. I'm not sure what you are supposed to do here.
to make this a pronoun case would I write it this way
Pedro Martinez signed a baseball for chad that he had used in a game.
I guess what you're asking is about the pronoun "he" -- right?
As it is, the sentence is not clear -- to whom does "he" refer? Pedro? Chad?? Somehow you need to revise that sentence to clear up the reference confusion.
