Which of the following adds a subordinate clause to the main clause below?

Question

Rochelle ate dinner.
A.
She was hungry. Rochelle ate dinner.
B.
She was hungry; Rochelle ate dinner.
C.
She was so hungry that Rochelle ate dinner.
D.
When she was hungry, Rochelle ate dinner.

Answer 1

The option that adds a subordinate clause to the main clause "Rochelle ate dinner" is:

D. When she was hungry, Rochelle ate dinner.

This option includes the subordinate clause "When she was hungry," which cannot stand alone as a complete sentence and adds additional information to the main clause.
