D. Betty started a new career making bowls and dishes out of clay after getting tired of teaching yoga. What is a complex sentence? A complex sentence is a sentence with an independent clause and a dependent clause joined by a subordinating conjunction. In a complex sentence, the dependent clause can come before or after the independent clause. The dependent clause cannot stand alone as a sentence. A complex sentence has a comma when the dependent clause comes first. An example of a complex sentence is: After Betty got tired of teaching yoga, she started a new career making bowls and dishes out of clay. (the dependent clause is "after Betty got tired of teaching yoga," and the independent clause is "she started a new career making bowls and dishes out of clay.") In option D, Betty started a new career making bowls and dishes out of clay after getting tired of teaching yoga, is a complex sentence. It contains an independent clause "Betty started a new career making bowls and dishes out of clay" and a dependent clause "after getting tired of teaching yoga" joined by a subordinating conjunction "after."
Hope it helps!
