Educational worksheet focusing on compound subjects and predicates, providing definitions and practice exercises.

Task Overview:

The task requires analyzing each sentence to identify the subject and the predicate, and then determining whether the sentence contains a compound subject, a compound predicate, or both. Here's a breakdown of the key concepts:

- Subject: The part of the sentence that performs the action or is described.
- Predicate: The part of the sentence that tells what the subject does or describes the subject.
- Compound Subject: A subject consisting of two or more simple subjects joined by "and" or "or."
- Compound Predicate: A predicate consisting of two or more verbs or verb phrases joined by "and" or "or."
