Hello!
The object preposition in the sentence; The brown dog chewed on the rawhide bone is ON.
Have a nice day!
maybe you've been invited to a party of a distant friend. while there, you meet someone who you'd never though you could be friends with. someone wayyy too different than you? but you two hit it off and they tell a really funny joke, hence where you'd use the line "i've never laughed so hard in my life."
hopefully this helps or gives you some sort of idea!
