Incomplete question. I inferred you want an explanation of the term parallelism.
Explanation:
The term parallelism is a literary device used in speech or literature. It involves the use of words or phrases with a close grammatical structure. It means the words or phrases are used repeatedly in other to create a clearer understanding of what is been said.
For example, Roosevelt used the expression "It can be helped by" repeatedly in the excerpt below,
"It [a better use of the Nation’s natural resources] can be helped by insistence that the Federal, State, and local governments act forthwith on the demand that their cost be drastically reduced. It can be helped by the unifying of relief activities which today are often scattered, uneconomical, and unequal. It can be helped by national planning for and supervision of all forms of transportation and of communications and other utilities which have a definitely public character."
By so doing he was able to make the problems stand out.
