Let's analyze each sentence to determine whether it is a Simple Sentence (SS), Compound Sentence (CS), or Complex Sentence (Complex).

---

Definitions:

- Simple Sentence (SS): Contains one independent clause (one subject and one predicate).
- Compound Sentence (CS): Contains two or more independent clauses joined by a coordinating conjunction (e.g., *and, but, yet, so*) or a semicolon.
- Complex Sentence: Contains one independent clause and at least one dependent clause (a clause that cannot stand alone).

Now, let’s go through each sentence:

1. The children wore their dirty boots.
→ One independent clause.
✔ SS

2. It was time for bed, yet it was still light outside.
→ Two independent clauses: "It was time for bed" and "it was still light outside," joined by the coordinating conjunction *yet*.
