How does Dr. Feltmate’s article show the importance of how claims change over time-space?

Read it and chapter 10 in Joel Best’s Social Problems (you can look into more if you want to, and feel free to look up the episodes mentioned in the article, but it’s not necessary as you are under a time crunch), and respond to this question:

1. How does Dr. Feltmate’s article show the importance of how claims change over time and space?
2. Why is it important to understand how claims change over time and how can you use that knowledge when evaluating claims today?
