The two correct responses that highlight the importance of the Emancipation Proclamation as a turning point in the Civil War are:
- The war became a battle for human rights and freedom.
- It opened the door for African Americans to enlist in the Union Army.
These responses reflect how the Emancipation Proclamation shifted the focus of the war toward the issue of slavery and human rights, and allowed for the participation of African Americans in the Union's fight, thereby strengthening the Union's efforts.
