…
Yes, 'n' how many years can some peopleexist
Before they're allowed to be free?
Yes, 'n' how many times can a man turn his head,
Pretending he just doesn't see?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.

Cryptic. But I hope Dylan meant the answer to be "as long as allowed."
