Hello. You did not show the sentences that the question is referring to, which does not allow me to combine them to create parallelism. Entretnaot, I will help you in the best possible way.
Parallelism is a literary device that allows the writer to construct complementary sentences with the same grammatical structure and function. This is very useful for showing harmony in the text and provoking cohesion and coherence.
An example of a phrase with parallelism is:
I like to run, play, dance, eat, read and jump rope, but I also like tranquility and peace.
