Here's why:
* Subject: The subject is the person or thing performing the action. In this case, the subject is Sharon.
* Predicate: The predicate tells us what the subject does or is. It includes the verb and all the words that modify the verb. Here, the verb is "tossed" and the rest of the predicate describes the action (tossed a dime to Perry).
