Read the excerpt.
from The White Knight's Song
I'll tell thee everything I can:
There's little to relate.
I saw an aged, aged man,
A-sitting on a gate.
"Who are you, aged man?" I said.
"And how is it you live?"
And his answer trickled through my head,
Like water through a sleve.
(from "The White Knight's Song" by Lewis Carroll)
Which does the simile in the last two lines mean?
1. The speaker's head was empty.
2. The man's ideas flowed rapidly.
3. The answer amused the speaker.
4. The answer was quickly forgotten.
