A compound-complex sentence contains at least two independent clauses and at least one dependent clause. Among the options you provided:
- "After dancing for many years, Jordan began teaching dance." (One independent clause and one dependent clause)
- "Over the summer, Jordan taught dance to children, and Mara danced in the recital." (Two independent clauses, no dependent clause)
- "Jordan is a dance teacher, and she loves her job." (Two independent clauses, no dependent clause)
None of these sentences qualify as a compound-complex sentence.
If you need an example of a compound-complex sentence, it might look like this: "After dancing for many years, Jordan began teaching dance, and she loves sharing her passion with others."
