Answer:
With reformist Alexander Dubcek.
Explanation:
"Socialism with human face" was the main slogan of a popular movement demanding more freedom and a relaxation of strict communist political control in Czechoslovakia in 1968. It was known as the Prague Spring. Alexander Dubcek was elected as a top Communist leader and he supported reforms. However, the Soviet Union´s and the socialist camp´s reaction was rejection. 200,000 Soviet and 400,000 other troops from "brotherly" socialist countries entered Czechoslovakia and suffocated the Prague Spring. Dubcek was removed from power and arrested. Soviet tanks occupying the streets of Prague are representative images of that historical moment.
The Civil Rights Act of 1964 marked a huge turning point in the Civil Rights movement. This law made it so that employers could not discriminate against candidates based on race, gender, religion, or birth place. This law helped to ensure that African-Americans would be able to be judged based on their qualifications/skills rather than their skin color. Any employer who broke this law could face federal charges.
