Just read this over to see if this sounds good. It's my intro paragraph. Give me some insight if I need to change anything. Like my thesis or something. People of the past and present judge each other by their class. This could relate to how much wealth they have as well as their social class or economic status. These judgements separate us as a society and live our lives around these judgments. Class in simple words is a group of people or things categorized by the quality and economic status. This relates to the novel "The Great Gatsby" by some of the characters in the novel such as Tom and Daisy Buchanan.

This is just how I would write it, dosen't mean it's better, just personal preference

Step-by-step explanation:

People of the past and the present judge each other based on class. This could be a social or an economic status or class difference and these judgements separate us as a society. Class in simple words is a group of people or things categorized by the quality and economic status. This relates to the novel "The Great Gatsby" by some of the characters in the novel such as Tom and Daisy Buchanan.

I don't know why you are defining class here but there might be some context I'm missing. In most scenarios though, defining a term is not a priority and is defentetly making the introduction run on for a while.

I would add a sentence before the last sentence futher tying in what your introduction has to relate with the book or at least some words like: "and this is shown in the Great Gabsy" or something like that
