To respond to this question, one must enter the mindset of the progressives and moderate socialists, and you need to differentiate between them when necessary. What were their basic ideas and values? What was the reasoning behind what they tried to do? Do not simply "list" progressive reform legislation, although you should point to examples of specific legislation to support you points. Do not simply retell the story in the Jungle either. Instead, focus on explaining the values, logic, and beliefs behind the reforms the progressives and moderate socialists promoted. When it is appropriate, use examples and quotations from Sinclair to illustrate your argument, citing specific pages from The Jungle.
