Step-by-step explanation:
The above sentences were rewritten to create parallelism.
Parallelism is a rhetorical device which refers to the repetition of a particular grammatical structure in a sentence. It provides clarity and balance in a sentence where it is employed. It also gives the sentence pattern and rhythm.
In the rewritten sentences, we discover that each of the phrases that make up the sentence follow the same grammatical structure. You will observe the structure as used after each comma and/or the conjunction, "and" in each sentence.
