Ok, wow, that is asking a lot. Is this for a research paper? Have you come up with a rough draft of any of the answers to these 7 prompts? Do you have a text for what I am assuming is a film class. If so, use the index & chapter headings to map out where you might find these answers. Skim over the material & jot down some notes. If something is unclear, go back & read it more thoroughly.
If you do not have a text, you can try the Library of Congress website. They have reference material on just about anything possible. You can IM or email them, but emailing does take time for a response. I would just do a search on "the changes in Hollywood movies since 1950" & see what it turns up. They have an entire film/movie section too.
If I think of another reference I will post it, but keep in mind that Librarians are your friend, use them.
Best of luck & keep well.
