Final answer:
The New York City Draft Riots of July 1863 showed that some people in the Union did not support the war, as they violently protested against the draft and the Emancipation Proclamation, expressing their discontent through racial violence and destruction of property. The correct option is b).
Step-by-step explanation:
The event that showed that some people in the Union didn’t support the war is b) New York City draft riots. During the Civil War, Northern discontent grew due to various reasons, including the Enrollment Act, that allowed wealthy individuals to pay for substitutes to avoid being drafted, leaving the poorer class to be conscripted.
This led to the infamous draft riots in New York City in July 1863, where working-class citizens, particularly among immigrants and Democratic Party supporters, displayed their opposition to the war and the Emancipation Proclamation by violently lashing out against draft offices, African American citizens, and property.
The Emancipation Proclamation added to the tension as many feared it would lead to freed slaves competing for jobs. The New York City Draft Riots involved looting, destruction of property, racial violence, and the lynching of African Americans, reflecting the degree of opposition and racial tension within parts of Northern society.
Over four days, the riots caused significant casualties and destruction until Union soldiers, some from Gettysburg, suppressed the unrest. Option b) is the correct one.
