Sentence numbers 3, 4, 7, and 10 are the choices that contain parallelism.
Parallelism (in a sentence) is when all parts of the sentence match in tense, structure, and meaning. The purpose of parallelism in a written work is to provide structure and balance in a sentence, and is also easier to read.
Examples of parallelism include:
