56. Which of which of the following is a compound-complex sentence?
Answer: D
Since we like to go on roller coasters, we go all the time, but we have not been on that coaster yet.
This sentence qualifies as a compound-complex sentence because it contains at least two independent clauses and one dependent clause. The dependent clause "Since we like to go on roller coasters" is combined with the independent clauses "we go all the time" and "we have not been on that coaster yet," showcasing the necessary complexity.
A) I want to go on vacation with Sally to Mexico, Costa Rica, and Florida.
This sentence is a simple sentence as it contains only one independent clause without any dependent clauses. It lacks the required elements of complexity found in a compound-complex sentence.
B) Even though the sun was shining, my mother told me I could not go to the pool.
While this sentence contains a dependent clause ("Even though the sun was shining") and an independent clause ("my mother told me I could not go to the pool"), it is not a compound-complex sentence. It consists of only one independent clause, thus failing to meet the criteria for a compound-complex structure.
C) Holly needs to go to the grocery store, but she does not have enough time to go there today.
This sentence is a compound sentence because it contains two independent clauses joined by the conjunction "but." However, it does not have a dependent clause, so it cannot be classified as a compound-complex sentence.
D) Since we like to go on roller coasters, we go all the time, but we have not been on that coaster yet.
This option is a compound-complex sentence as it includes one dependent clause ("Since we like to go on roller coasters") along with two independent clauses ("we go all the time" and "we have not been on that coaster yet"). This structure exemplifies the definition of a compound-complex sentence.
Conclusion
Option D is definitively the correct answer because it fulfills the requirements of a compound-complex sentence by incorporating both dependent and independent clauses. The other options fail to meet these criteria, being either simple or compound sentences without the necessary complexity. Thus, D stands out as the only valid choice.
