which sentence contains parallel structure?\no mekhi was finally finished with his chemistry homework.\no mekhi finished his chemistry homework before basketball practice.\no mekhi spent three hours finishing his chemistry homework.\no mekhi finished his chemistry homework and then finished his essay.

Answer

Brief Explanations:

Parallel structure uses the same grammatical form for related ideas. In "Mekhi finished his chemistry homework and then finished his essay", both parts use the verb - past tense + object structure. The other sentences do not have parallel elements.

Answer:

Mekhi finished his chemistry homework and then finished his essay.
