Question

PLEASE HELP!!

Answer 1

Answer: act as a single unified sentence

Explanation: I suspect this is the answer, because usually it would be like a list. And the list wouldn’t usually be separated in different sentences

Answer 2

Answer:

be the same part of speech

Explanation:

Parallelism consists in using words, phrases or clauses with an identical grammatical form. Therefore, for a series of three or more items to be a parallel structure, they must be the same part of speech.

e.g. "My favorite camping activities are fishing, hiking, and swimming."

This sentence uses three gerunds fishing, hiking, and swimming as predicative nouns.  This is correct parallel structure.
