Question 1-26 Which cause united many college students, civil rights activists, and labor union members during the 1960s? Protecting the world against climate change Expanding presidential use of executive privilege Using detente as a foreign policy with China Opposing U.S. participation in the Vietnam War

The correct answer is: Opposing U.S. participation in the Vietnam War.<br /><br />During the 1960s, many college students, civil rights activists, and labor union members united in their opposition to the U.S. participation in the Vietnam War. The Vietnam War was a highly controversial and divisive issue in the United States during this time period. Many young people, particularly college students, were deeply opposed to the war and saw it as an unjust and unnecessary conflict. Civil rights activists also saw the war as a distraction from the more pressing domestic issues of racial inequality and social justice. Labor union members were concerned about the impact of the war on working-class families and the economy. As a result, these groups often came together to protest and organize against the U.S. government's involvement in Vietnam.
