Identify sentence types: simple, compound, or complex.

Here's the solution to your sentence classification task, with clear explanations for each:

---

1. The children wore their dirty boots.
✔ SS (Simple Sentence)
*Explanation:* One independent clause: subject (“The children”) + verb (“wore”) + object (“their dirty boots”). No dependent clauses or coordinating conjunctions joining multiple independent clauses.

---

2. It was time for bed, yet it was still light outside.
✔ CS (Compound Sentence)
*Explanation:* Two independent clauses joined by the coordinating conjunction “yet”:
- Clause 1: “It was time for bed”
- Clause 2: “it was still light outside”
Each can stand alone as a complete sentence.

---

3. The front door was locked, so she entered through the back.
✔ CS (Compound Sentence)
*Explanation:* Two independent clauses connected by the coordinating conjunction “so”:
- Clause 1: “The front door was locked”
- Clause 2: “she entered through the back”
Both are complete thoughts.

---

4. They took a lot of pictures when they visited Montana.
✔ Complex
*Explanation:* One independent clause (“They took a lot of pictures”) + one dependent clause (“when they visited Montana”) introduced by the subordinating conjunction “when.” The dependent clause cannot stand alone.

---

5. After the show began, he sat very quietly.
✔ Complex
*Explanation:* Dependent clause (“After the show began”) + independent clause (“he sat very quietly”). “After” is a subordinating conjunction introducing the dependent clause.

---

6. The girl was wearing a red dress.
✔ SS (Simple Sentence)
*Explanation:* Single independent clause: subject (“The girl”) + verb (“was wearing”) + object (“a red dress”). No extra clauses.

---

7. He was playing on his computer.
✔ SS (Simple Sentence)
*Explanation:* One subject (“He”), one verb phrase (“was playing”), and prepositional phrase (“on his computer”). Still only one independent clause.

---

8. Before the bell rings, the student lined up at the door.
✔ Complex
*Explanation:* Dependent clause (“Before the bell rings”) + independent clause (“the student lined up at the door”). “Before” introduces the dependent clause.

> ⚠️ Note: There’s a slight tense mismatch (“rings” vs. “lined”), but grammatically it’s still complex — the structure defines the sentence type, not tense consistency.

---

9. We turned off the lights.
✔ SS (Simple Sentence)
*Explanation:* One subject (“We”), one verb (“turned off”), one object (“the lights”). Simple and complete.

---

10. We turned off the lights after our mom told us to go to sleep.
✔ Complex
*Explanation:* Independent clause (“We turned off the lights”) + dependent clause (“after our mom told us to go to sleep”) introduced by “after.”
