You have to decide what you want to say. Are the settings alike? Are they different? How?
Ok so one setting is poor/ sharecropper and the other once used to be rich and on the most selective street now its full of machines and factories.
So what do you have to say about this? Can you support it with exerpts from the stories?
Here are some ideas for you.
First -- about thesis statements:
Do you have a thesis yet? Have you done your brainstorming (and maybe research) yet? Have you written an outline?
Check in the Essay & Research Paper Level.
Second, about comparison/contrast writing:
Whenever you are writing a comparison/contrast paper (paragraph, essay, research paper), you need to plan it out very carefully on paper first.
1. Write all the information about one of your topics on one page.
2. Write all the information about the other topic on another page.
3. Then put them together in this order:
2. All about topic A
~~~2A. detail 1
~~~2B. detail 2
~~~2C. detail 3
~~~2D. detail 4
~~~2E. detail 5
3. All about topic B
~~~3A. detail 1
~~~3B. detail 2
~~~3C. detail 3
~~~3D. detail 4
~~~3E. detail 5
The number of details for each topic will vary depending on your main points. I would include comparisons (how they are similar) in the introduction and conclusion, but sections 2 and 3 and all those details will be stating and explaining how they are different.
There are two recognized patterns for writing comparison/contrast papers. One is casually referred to as "zig-zag,” but can be very confusing for the reader if you don’t use transitions effectively. The other is topic-by-topic (which is what I've outlined above) and is much easier for the reader to follow.
