Which sound device(s) best describes this passage?
parallelism: repeating a grammatical structure or arrangement of words to create a sense of rhythm and momentum .

repetition: expressing different ideas using the same words or images in order to reinforce concepts and unify the speech .
analogy: drawing a comparison that shows a similarity between unlike things .
"in the field of world policy i would dedicate this nation to the policy of good neighbor-the neighbor who resolutely respects himself rights of others."
explanation:

In this passage, the author mentions "the policy of good neighbor" and then defines it further as having "respect [for] himself and...the rights of others."

We know that the answer can't be parallelism because no group of words is actually repeated for any effect.
While "the policy of good neighbor" is put into different words for those who don't know the term, this is not to reinforce concepts, and so it's not repetition.
I would say the goal was more to clarify the term, which would be a restatement.

It is an analogy, either--the author says a nation's policy is defined by a certain ideal, but there is no strong or clear comparison made.
