Which piece of legislation, passed in 1964, outlawed discrimination based on race, color, religion, sex, or national origin?

The Civil Rights Act of 1964 is a landmark piece of legislation that played a crucial role in the civil rights movement in the United States. This act was pivotal in outlawing discrimination in various areas, including employment, education, and public accommodations, specifically on the grounds of race, color, religion, sex, or national origin.

By addressing systemic discrimination, the Civil Rights Act aimed to promote equality and safeguard the rights of individuals, reflecting the broader goals of the civil rights movement during that era. It set a legal precedent that facilitated further advancements in social justice and equality for African Americans and other marginalized groups.

The other options do not pertain to the specific legislation aimed at ending discrimination in the same breadth and scope. The Voting Rights Act focuses specifically on voting access and rights for African Americans, the Emancipation Proclamation was a wartime executive order that freed slaves in Confederate states, and the Fourteenth Amendment primarily addresses citizenship and equal protection under the law. These pieces contribute to the wider context of civil rights but do not directly represent the comprehensive anti-discrimination stance of the Civil Rights Act of 1964.
