How to get fetch second paragraph data from JSON Data?

Hello how do i fetch data from second paragraph of JSON Data.
i mean i have a data like

          Para 1: Lorem Ipsum is simply dummy text of the printing and typesetting industry. 

          Para 2: Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.

i tried to use .substr(0, 80) but its not always sure when first para will end.

Is there something i can use to fetch data from “Para2:” instead from the start?
