problem/cause/solution
The passage first identifies the problem as the tires "piling up in empty lots." Then it is explained how those tires got there: the cause. The author says that since "it is expensive and dangerous to dispose of tires" people don't dispose of them and they just keep piling up. Then the passage ends with a solution. The author mentions how tires can be shredded and turned into rubberized asphalt for paving projects.
A conjunction can be placed after the comma to make the sentence make sense (i.e. and, so, ect).
I would say that these are the two thesis statements best for a literary analysis essay on recurring themes in Shakespeare's Romeo and Juliet:
1. In Romeo and Juliet, Shakespeare demonstrates that love comes in a variety of forms, be it romantic, familial, or between friends.
2. Shakespeare explores the struggle for identity through the character of Juliet in his play Romeo and Juliet.
The other theses aren't reoccurring in this play.
A. Cooperation is an important value in this culture.
