The correct answer is D. Compound-complex sentence
Explanation:
Complex sentences different from simple or compound sentences always include a dependent clause connected to an independent clause. In the case of the sentence presented "Before the car wash" is the dependent clause because this does not express a complete idea and includes the word "before" that is a subordinating conjunction and "Tanya made signs and Gabe signed up volunteers" is the independent clause as this expresses a complete thought. Besides this, a sentence is compound if two ideas of the same importance are included and joined by a conjunction such as and, or, but, which occurs in "Tanya made signs and Gabe signed up volunteers". This means the sentence includes the elements of a complex sentence (independent-dependent clause) and a compound sentence (two independent clauses) and therefore it is a compound-complex sentence.
Answer: D
The first passage presents factual information about the Mississippi River, while the second passage simply uses the Mississippi River for plot points and setting.
The answer is: There is no error.
Complex sentences consist of a subordinate or dependent clause, which is introduced by a subordinating conjunction like <em>even though</em>, and an independent clause, which can stand on its own. They can be separated by a comma.
In the example sentence, the subordinate clause is:
Even though I had no previous experience,
Finally, the independent clause is:
I enjoyed painting the living room with my friends.
The rest of the alternatives are incorrect because the clauses are separated or do not express the same meaning as the original sentence.
