Answer:
- classic children's books
- children's books by Margery Williams
- The Velveteen Rabbit
- the theme of friendship
Step-by-step explanation:
Topics in the given problem are limited based on specifically chosen aspects.
The broadest topic given is "classic children's books" - there are thousands of them.
However, "children's books written by Margery Williams" is a narrower topic - all children's books written by Williams are included in the topic of "classic children's books", but there are much fewer books written by that author, so the topic applies to much fewer works.
The Velveteen Rabbit takes a single children's book by Margery Williams. It is much more specific than the topic of "Children's books", because it focuses on a single children's book. This is narrower than both the previous topics.
"The theme of friendship in The Velveteen Rabbit" is the narrowest topic given. It takes a book from a collection of books by an author and looks at one of its themes. This is a narrower topic than The Velveteen Rabbit because that topic applies to the broader book, whereas this topic focuses only on its theme. Therefore, this is a narrower topic.
