All are complex sentences except for #9. It's a compound sentence.

IS NUMBER 9 A MAIN CLAUSE

No, it's a compound sentence -- which means there are two main clauses there.

To determine if these sentences are complex, we need to understand what a complex sentence is. A complex sentence is a sentence that contains an independent clause (a complete thought) and at least one dependent clause (an incomplete thought).

Let's go through each sentence and analyze if it meets the criteria:

1. "I will help you with your homework after you watch the baby."
- This sentence has an independent clause ("I will help you with your homework") and a dependent clause ("after you watch the baby"). Therefore, it is a complex sentence.

2. "Jake stared at me as if he had seen a ghost."
- This sentence has an independent clause ("Jake stared at me") and a dependent clause ("as if he had seen a ghost"). Therefore, it is a complex sentence.

3. "You can order whatever you want from the menu."
- This sentence has an independent clause ("You can order whatever you want") but no dependent clause. Therefore, it is not a complex sentence. It is a simple sentence.

4. "We will be on time unless there is a traffic jam."
- This sentence has an independent clause ("We will be on time") and a dependent clause ("unless there is a traffic jam"). Therefore, it is a complex sentence.

5. "If our team wins, everyone will celebrate."
- This sentence has an independent clause ("Everyone will celebrate") and a dependent clause ("If our team wins"). Therefore, it is a complex sentence.

6. "The police did not arrive until the thieves had left."
- This sentence has an independent clause ("The police did not arrive") and a dependent clause ("until the thieves had left"). Therefore, it is a complex sentence.

7. "Jill had her petition filled out so that she could run for office."
- This sentence has an independent clause ("Jill had her petition filled out") and a dependent clause ("so that she could run for office"). Therefore, it is a complex sentence.

8. "Sandy cried because her dog ran away."
- This sentence has an independent clause ("Sandy cried") and a dependent clause ("because her dog ran away"). Therefore, it is a complex sentence.

9. "The rain ceased, and the stuffy air cleared."
- This sentence has two independent clauses ("The rain ceased" and "the stuffy air cleared") connected by a coordinating conjunction ("and"). Therefore, it is a compound sentence, not a complex sentence.

10. "Since I first saw you, I have wondered if we ever met before."
- This sentence has an independent clause ("I have wondered if we ever met before") and a dependent clause ("Since I first saw you"). Therefore, it is a complex sentence.

In summary, the complex sentences in the given list are:
1. "I will help you with your homework after you watch the baby."
2. "Jake stared at me as if he had seen a ghost."
4. "We will be on time unless there is a traffic jam."
5. "If our team wins, everyone will celebrate."
6. "The police did not arrive until the thieves had left."
7. "Jill had her petition filled out so that she could run for office."
8. "Sandy cried because her dog ran away."
10. "Since I first saw you, I have wondered if we ever met before."
