Discussion on how to construct a well-written introductory paragraph for a literary analysis essay

Discussion on how to construct a well-written introductory paragraph for a literary analysis essay.

The work and theme for this introductory paragraph is "Innocence and Experience in Indian Camp." This is a short story by Ernest Hemingway.

For this, I choose two literary techniques to express a single theme in a piece of literature.

The two suggested literary devices are 

1. The protagonist

2. The Plot 

The thesis, or main claim of the essay, should answer the questions: What literary devices will be analyzed? And what theme does the writer convey with the literary devices?
