Final answer:
The Civil Rights Act of 1964, specifically Title VII, prohibits discrimination in the workplace based on race, color, religion, sex, and national origin. It does not cover educational discrimination, and age discrimination is addressed by separate legislation.
Step-by-step explanation:
Title VII of the Civil Rights Act of 1964 is a critical piece of legislation that protects employees from workplace discrimination. Specifically, as amended, Title VII prohibits employment discrimination on the basis of several categories: race, color, religion, sеx, and national origin.
Among the choices given in the question, religious discrimination and gender discrimination are explicitly mentioned as being unlawful under Title VII. The Act does not mention educational discrimination. While age discrimination is certainly illegal, it is covered by a different legislation known as the Age Discrimination in Employment Act (ADEA), which is not a part of Title VII.
There have been amendments to the Civil Rights Act over the years, such as the Pregnancy Discrimination Act of 1978 which further defined sex discrimination to include pregnancy, childbirth, or related medical conditions. However, the core protections against employment discrimination have been a monumental step in creating equal opportunities in the workplace.
