Question

Which passage from Grendel best illustrates the theme "life is meaningless"?

Answer 1

After a thorough research, there exists a question that has the following choices.

A) All order, I've come to understand, is theoretical, unreal -- a harmless, sensible, smiling mask men slide between the two great, dark realities. 
B) I seize up a sleeping man, tear at him hungrily, bite through his bone-locks and suck hot, slippery blood.
C) Fate often enough will spare a man if his courage holds. (162)
D) As if casually, in plain sight of them all, I bit his head off, crunched through the helmet and skull with my teeth and, blood-slippery body in two hands. (79)

The correct answer is letter A) All order, I've come to understand, is theoretical, unreal -- a harmless, sensible, smiling mask men slide between the two great, dark realities. 

Answer 2

I have found the choices to your question from another source and I will place them here:

A) All order, I've come to understand, is theoretical, unreal -- a harmless, sensible, smiling mask men slide between the two great, dark realities. B) I seize up a sleeping man, tear at him hungrily, bite through his bone-locks and suck hot, slippery blood.C) Fate often enough will spare a man if his courage holds. (162)D) As if casually, in plain sight of them all, I bit his head off, crunched through the helmet and skull with my teeth and, blood-slippery body in two hands. (79)

Among these choices, the passage that would suggest that "life is meaningless" would be option A. That passage suggests that every order is not real, that people just unknowingly go over between the "two dark realities".

It supports that life is meaningless by telling us that the order we try so much to achieve and maintain is nothing but a theoretical concept - an imagination.
