Let's go through each item and determine whether it is a fragment, a run-on, or a sentence.

---

Definitions:


- Sentence: A complete thought with a subject and predicate, and it expresses a complete idea. It can be declarative, interrogative, imperative, or exclamatory.
- Fragment: An incomplete sentence — missing a subject, a verb, or a complete thought.
- Run-on: Two or more independent clauses joined without proper punctuation or conjunctions (e.g., comma splice or fused sentence).

Now, let’s analyze each one:

1. Please call me later.
✔ This is an imperative sentence (a command). It has a subject ("you," implied) and a verb ("call").
→ Sentence

2. Who won?
✔ This is an interrogative sentence — it asks a question and has a subject ("who") and verb ("won").
→ Sentence

3. Disturbing the peace.
✘ This is a phrase, not a complete sentence. No subject or main verb; just a participle phrase.
→ Fragment

4. My opinion is that you should keep the kitten, it needs a good home.
✘ This is a run-on: two independent clauses joined by a comma (comma splice).
- Clause 1: "My opinion is that you should keep the kitten"
- Clause 2: "It needs a good home"
→ Run-on

5. Copying the lesson from the book.
✘ Again, this is a participial phrase — no subject or finite verb.
→ Fragment

6. A soccer ball was kicked to the far end of the field.
✔ Subject ("a soccer ball"), verb ("was kicked"), complete thought.
→ Sentence

7. Mother drove the car Dad flew.
✘ This is a fused sentence (run-on). Two independent clauses:
- "Mother drove the car"
- "Dad flew" (but "flew" what? It's ambiguous, but still a clause).
Should be separated with a period or conjunction.
→ Run-on

8. Talking on the telephone at the end of the day.
✘ Just a phrase — no subject or verb.
→ Fragment

9. A snake slivered under a rocker.
✔ Subject ("a snake"), verb ("slivered"), complete thought.
→ Sentence

10. With winter approaching, I become more anxious about skiing, sledding is going to be fun too.
✘ Run-on: Two independent clauses joined by a comma.
- "I become more anxious about skiing"
- "Sledding is going to be fun too"
→ Run-on

11. Be prepared to make sudden stops on this road.
✔ Imperative sentence — "be" is the verb, "you" is implied subject.
→ Sentence

12. Unless Mrs. Farmington calls.
✘ Dependent clause — starts with a subordinating conjunction ("unless") and lacks an independent clause.
→ Fragment

13. They ran out the door, I followed them.
✘ Comma splice — two independent clauses joined by a comma.
→ Run-on

14. We went swimming last summer.
✔ Complete thought: subject ("we"), verb ("went"), time frame.
→ Sentence

15. The ball field is past Joan's house.
✔ Subject ("the ball field"), verb ("is"), complete thought.
→ Sentence

16. The students enjoyed the break, the teachers did also.
✘ Run-on — two independent clauses joined by a comma.
→ Run-on

17. Did you put your name on your paper?
✔ Interrogative sentence — subject ("you"), verb ("did put"), complete question.
→ Sentence

18. Since George was late.
✘ Dependent clause — starts with "since" and cannot stand alone.
