To whom is Faulkner addressing his speech

Young writers

The correct answer is: up-and-coming young writers.

Explanation:

William Faulkner's Nobel Prize Acceptance Speech was addressed to all up-and-coming young writers, "already dedicated to the same anguish and travail, among whom is already that one who will someday stand here where I am standing".

In his speech, he talks about the young people who have forgotten the problems of spirit and human heart, and he invites all young writers to write about these things in order to be able to make good writing.

William Faulkner gave this speech at the Nobel Banquet at the City Hall in Stockholm, on December 10, 1950, after receiving the Nobel Prize in Literature.
