What does a predicate in a sentence modify?

The correct choice highlights that a predicate encompasses both the subject and includes the verb of a sentence. In essence, the predicate provides essential information about what the subject is doing or what state it is in. It typically follows the subject and includes the verb alongside any additional modifiers or objects. For example, in the sentence "The dog barks loudly," "barks loudly" serves as the predicate, indicating the action (verb) of the subject ("the dog").

The other options do not accurately represent the role of a predicate. For example, while it concerns objects as part of its function, it does not modify objects exclusively, nor does it solely modify adjectives or the entire sentence. By defining the predicate this way, it clarifies its integral function in expressing meaning and action related to the subject. Understanding the concept of a predicate is key to grasping sentence structure and grammar in business writing and communication.
