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 means using the same pattern of words to show that two or more ideas have the same level of importance. In the sentence "Mekhi finished his chemistry homework and then finished his essay", the verb - phrase structure "finished his [noun]" is repeated for both the chemistry homework and the essay, creating a parallel construction. The other sentences do not have this consistent pattern.

Answer:

Mekhi finished his chemistry homework and then finished his essay.
