With respect to some concepts expressed here, I would like to add that if ppt is used primarily to graph concepts rather than to repeat texts, the teacher can constantly improvise and emphasize when he understands that it corresponds.

What is the passage about
The term "vetted" means "to make a careful examination," or "to investigate someone thoroughly." It is commonly used to ensure someone is trustworthy for a job.

In the beginning of "The Great Gatsby", Nick brags that he is not at all judgmental and is able to understand where people are coming from. This leads him to trusting people and thinking the best of them. By the end of the novel, after he has had so many uncomfortable and unfortunate experiences tangled up in the lives of Gatsby, Daisy, Tom, Jordan, etc, Nick finds himself to be very judgmental of their lifestyle and personalities, especially the Buchanans. He removes himself from their company and becomes more reserved, less trusting.
