Answer:
B) I called for Sadie. Sadie didn't answer. I waited up for Sadie. Sadie didn't come home.
Step-by-step explanation:
Parallelism is the repetition of a grammatical form within a sentence or text. Options A and B show this literary device quite distinctly: sentence A uses simple present tense verbs, and B, simple past tense verbs.
However, a sad tone is created only in B.
Additionally, in B, the first and third sentences are affirmative statements while the second and fourth sentences are negative statements. This pattern can also be considered part of parallelism created by the writer.
