Answer:
The subject of the sentence is "Andre" and the verb/predicate is "like."
Step-by-step explanation:
To determine the subject and predicate/verb of a sentence, you need to identify who or what is performing the action (subject) and what action is being done (verb/predicate). In this case, "Andre" is the subject, as he is the one who may or may not like the slice of pizza. The verb/predicate is "like," indicating the action of Andre potentially having a preference for the pizza.
