Select the correct answer. which of these sentences uses correct parallel structure? a. after school, sheila either walks home or is taking a bus. b. every evening, jenny does her homework and then took her dog for a walk. c. on the airplane, shane read a book, watched a movie, and was playing his favorite music. d. before starting college, jake learned how to speak spanish and traveled across south america.

The correct answer is D. This sentence is a perfect example of parallel structure because either after and before AND it in both cases uses simple past tense verbs which are LEARNED AND TRAVELED. The other sentences never show parallelism due to their units are never the same. For example, in letter A , it uses a verb in simple present WALKS AND a progressive tense verb which is TAKING. So, to sum up, for a sentence to be considered parallel, it must be coherent in its structure and internal words. They need to have harmony and unity in tenses as well.
