Question

which sentence contains parallel structure? mekhi was finally finished with his chemistry homework. mekhi finished his chemistry homework before basketball practice mekhi spent three hours finishing his chemistry homework mekhi finished his chemistry homework and then finished his essay

Explanation:

Parallel structure requires using the same grammatical form for related items. In "Mekhi finished his chemistry homework and then finished his essay", both parts of the compound sentence use the simple past tense verb "finished" for the actions, creating parallelism. The other options lack this consistent grammatical structure for multiple related actions.

Answer:

Mekhi finished his chemistry homework and then finished his essay
