Identify the sentence that has a prepositional phrase underlined.

a. i tried to eat broccoli once, but i found that i don’t like it.
b. parasailing is just one of my many hobbies.
c. i put all my shopping bags on the counter.

a. Think of it as which sentence has a piece in it that adds more detail, but the details do not affect whether or not the sentence is complete.  "I tried, but I found that I don't like it" can stand alone. Adding the "what did you try" makes it better, but not complete. "I put all my shopping bags" is incomplete and "Parasailing is just one" is incomplete.

Make sense?
