Answer:
Walden by Henry David Thoreau
A precursor to Granger's philosophy in Fahrenheit 451, Thoreau's classic account of the time he spent in a cabin on Walden Pond has inspired generations of iconoclasts to spurn society and take to the wilderness.
Gulliver's Travels by Jonathan Swift
Swift's satirical 1726 novel follows the journey of Lemuel Gulliver to a series of fanciful islands, none more improbable than the England he left behind. The Bradburian idea of using a distant world as a mirror to reflect the flaws of one's own society doesn't originate here, but this is one early expression of it.
"Dover Beach" by Matthew Arnold
Arnold's enduring poem about a seascape where "ignorant armies clash by night" has also lent lines to Ian McEwan's novel Saturday, and provided the title for Norman Mailer's Armies of the Night.
The Republic by Plato
The deathless allegory of the cave, where men living in darkness perceive shadows as truth, is unmistakably echoed in the world of Fahrenheit 451.

The correct answer is A: Unimportant.
An example of an extra in a movie is when the main characters are walking down the street in Manhattan and there are a bunch of people walking in the background. The people that are walking in the background are the extras because they are unimportant for the scene. Extras are there so when you watch a show, movie, broadway, e.t.c, it won't look like the performance is empty. Just think of how the main characters would be walking down the street with an empty road around them. How much more boring than having extras in the background would that be?
I hope this helped! Stay cool! :-)
