I am not sure what you are asking here. If you are asking what parallel structure looks like, you would have to keep the verb tenses the same. For example, Sam likes to ride bikes, hike trails, and bake bread. What is does NOT look like: Sam likes to ride bikes, go hiking on trails, and baked bread with her grandmother. The structure words would be based of the passage you were given, which isn't supplied here. If you were asked to write a paragraph using a parallel structure, follow the example given here.
