📝 Tips for Students:

- Look for the main noun (subject) — who or what the sentence is about.
- Find the main verb (predicate) — what the subject is doing.
- Ignore extra descriptive words like adjectives, adverbs, or prepositional phrases.
- Compound subjects (like "Lance and Phyllis") are both part of the simple subject.
