Question

which sentence or sentences have correct parallel structure?
kiaras plans for the summer include volunteering at a shelter, working a part-time job, and visiting relatives in california.
kiaras plans for the summer include volunteering at a shelter, working a part-time job, and they might also include visiting relatives in california.

Explanation:

Parallel structure requires consistent grammatical form for items in a list. The first sentence uses three gerund phrases (volunteering..., working..., visiting...) that match in structure. The second sentence breaks parallelism by switching to an independent clause ("they might also include visiting...") instead of maintaining the gerund phrase pattern.

Answer:

Kiara's plans for the summer include volunteering at a shelter, working a part-time job, and visiting relatives in California.
