What concept do both speeches have in common? A. The world will never remember how hard they worked. B. People will write down all of their names so that no one will confuse the situation. C. Women should have the right to vote because they are legally included as citizens of this country, too. D. Perhaps names will be forgotten, but the sacrifice for freedom will always be appreciated.

Passage: Nobel Peace Prize Acceptance:
Most of these people will never make the headline and their names will not appear
in Who's Who. Yet when years have rolled past and when the blazing light of truth
is focused on this marvellous age in which we live—men and women will know and
children will be taught that we have a finer land, a better people, a more noble
civilization—because these humble children of God were willing to suffer for
righteousness' sake.

Gettysburg Address:
The world will little note, nor long remember what we say here, but it can never
forget what they did here. It is for us the living, rather, to be dedicated here to the
unfinished work which they who fought here have thus far so nobly advanced. It is
rather for us to be here dedicated to the great task remaining before us—that from
these honored dead we take increased devotion to that cause for which they here
gave the last full measure of devotion—that we here highly resolve that these dead
shall not have died in vain.
