Questions: What tactic did American Indian activists use in the 1960s and 1970s that differed from tactics used by African American and Hispanic American activists? A. Seizing control of government property to gain national attention B. Organizing boycotts of both government services and private businesses C. Refusing to accept Supreme Court rulings as legitimate or constitutional D. Organizing mass demonstrations to protest racial discrimination

The answer is A. Seizing control of government property to gain national attention.

American Indian activists in the 1960s and 1970s used the tactic of seizing control of government property to draw attention to their causes. A notable example is the occupation of Alcatraz Island from 1969 to 1971 by a group of Native American activists. This event was significant in raising awareness about Native American issues and rights. The occupation of the Bureau of Indian Affairs in Washington, D.C., in 1972, and the standoff at Wounded Knee in 1973, were other instances where this tactic was employed.

While boycotts were a common tactic used by various civil rights movements, including African American and Hispanic American activists, it was not a distinctive tactic of the American Indian movement during this period.

This option does not accurately reflect a specific tactic used by American Indian activists during the 1960s and 1970s. While there were legal challenges and disputes over treaties and land rights, outright refusal to accept Supreme Court rulings was not a prominent tactic.

Mass demonstrations were a common tactic used by African American and Hispanic American activists, such as the Civil Rights Movement's March on Washington in 1963. While Native American activists did organize protests, the tactic of seizing government property was more distinctive to their movement during this era.
