To write a thesis-driven essay to cover all that territory, I would first answer all of those questions, just briefly.
Then you need to ask yourself what thesis, what main idea, those answers lead you to.
I would write a brief introduction, naming the book and its author and a very brief synopsis of the book, placing my thesis statement as the last statement in the introduction.
Then I would use those supporting points to structure my body paragraphs, one for each point I want to develop.
This argument will in turn form the basis of your essay’s thesis statement.
The thesis of the essay will be your statement of interpretation of what a particular poem means.
While this is a good start, this idea is not specific enough to be a thesis.
The thesis should make an argument about Wordsworth’s perspective within the poem so that it can then be supported or proven in the rest of the essay.
The purpose of the rest of the essay is to provide support for your argument, or to prove your thesis with specific examples from the text.
For example, you might decide that William Wordsworth’s poem “Daffodils” is saying something about Wordsworth’s attitude toward life.
