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.
If you need to answer those questions then read the book again then answer the questions. What helps me is to reread the page or passage again
I could be the letter C or A
