Question

which of the following is a compound - complex sentence? while at school, we learned about atoms and molecules. the school days was long but rewarding. after we get done with school, i have to go to work, but luther has to go to practice.

Explanation:

A compound - complex sentence has at least two independent clauses and at least one dependent clause. "After we get done with school" is a dependent clause. "I have to go to work" and "Luther has to go to practice" are independent clauses. The first option has only one independent clause with a dependent clause. The second option is a simple compound sentence with a coordinating conjunction "but" joining two parts of the predicate in a single independent clause.

Answer:

After we get done with school, I have to go to work, but Luther has to go to practice.
