Explanation:
Let’s review what each sentence type means:
-
SS (Simple Sentence): Has one independent clause — a subject and a verb, and expresses a complete thought. It may have compound subjects or verbs, but no dependent clauses.
-
CS (Compound Sentence): Has two or more independent clauses joined by a coordinating conjunction (like *and, but, or, yet*) or a semicolon. Each clause could stand alone as a sentence.
-
Complex Sentence: Has one independent clause and at least one dependent (subordinate) clause — a clause that cannot stand alone (often starts with words like *after, before, when, because, if, since*, etc.).
Now let’s go through each sentence:
1.
The children wore their dirty boots.
→ One subject (*The children*), one verb (*wore*), no conjunctions or subordinating words.
✔ SS
2.
It was time for bed, yet it was still light outside.
→ Two independent clauses:
- *It was time for bed*
- *it was still light outside*
Joined by *yet* (a coordinating conjunction).
✔ CS
3.
The front door was locked, so she entered through the back.
→ Two independent clauses:
- *The front door was locked*
- *she entered through the back*
Joined by *so* (coordinating conjunction).
✔ CS
4.
They took a lot of pictures when they visited Montana.
→ Independent clause: *They took a lot of pictures*
Dependent clause: *when they visited Montana* (starts with *when* — can’t stand alone).
✔ Complex
5.

→ Dependent clause: *After the show began* (starts with *After*)
Independent clause: *he sat very quietly*
✔ Complex
6.

✔ SS
7.

10.

Dependent clause: *after our mom told us to go to sleep* (starts with *after*)
✔ Complex
Double-checking:
- SS: 1, 6, 7, 9 → 4 sentences
- CS: 2, 3 → 2 sentences
- Complex: 4, 5, 8, 10 → 4 sentences
All match.
