What does "identify one or more insights from the text" mean?

Your instructor most likely wants you to find quotations
in the book or story you're reading and explain how they relate to a particular theme or
topic.

For example, if I asked my students to find
"insights from the text" in the novel Fahrenheit 451 (a story that investigates the
value of books) that reveal attitudes towards literature, I would expect my students to
quote passages from the book that relate to the value of literature, and then clearly
explain to me how these passages show the different characters' thoughts and values
pertaining to books and reading.

Explaining the
relationship between the quotation and the topic your instructor asks you to discuss is
key; just finding a quotation in the book won't show your instructor that you understand
the "insight" it gives to the topic.
