Explanation:
Parallelism or Parallel structure makes an effect on the reader by making a balance in one or more sentences that have same grammatical structure. In this structure, it uses repetition of a grammatical form (same pattern of words) in one sentence. For example, in the sentence, Radha likes cooking, reading and playing guitar.
