Read the passage from "how should one read a book? ”

yet few people ask from books what books can give us. most commonly we come to books with blurred and divided minds, asking of fiction that it shall be true, of poetry that it shall be false, of biography that it shall be flattering, of history that it shall enforce our own prejudices. if we could banish all such preconceptions when we read, that would be an admirable beginning.

the reader can conclude that the passage comes from a(n)

biography.
essay.
myth.
play.
