Question

after returning to south africa from algeria in 1964, nelson mandela was
○ arrested and imprisoned.
○ elected to the presidency.
○ educated in guerrilla tactics.
○ finally granted his freedom.

Explanation:

To solve this, we recall Nelson Mandela's history. In 1964, after returning, he was arrested and imprisoned (the Rivonia Trial led to his imprisonment). He was elected president much later, learned guerrilla tactics before 1964, and was freed in 1990, not 1964.

Answer:

A. arrested and imprisoned.
