Answer:
D The nation should not rejoice until everyone has freedom.
Step-by-step explanation:
According to the excerpt from WHAT TO THE SLAVE IS THE FOURTH OF JULY by Frederick Douglass which he gave as a speech in Rochester, July 5, 1852, he talks to the audience about justice for the slaves because there was nothing really for the ex-slaves to rejoice about because there was no equality.
Therefore, one of the lessons Douglass impresses on his listeners is that the nation should not rejoice until everyone has freedom.
