after returning to south africa from algeria in 1964, nelson mandela was \n○ arrested and imprisoned. \n○ elected to the presidency. \n○ educated in guerrilla tactics. \n○ finally granted his freedom.
Answer
Brief Explanations:
To solve this, we analyze each option:
- "elected to the presidency": Mandela was elected president much later (1994), so this is incorrect.
- "educated in guerrilla tactics": He received guerrilla training in Algeria (before returning), not after returning to South Africa in 1964.
- "finally granted his freedom": He was released in 1990, not 1964.
- "arrested and imprisoned": In 1964, Mandela was arrested and sentenced to life imprisonment (part of the Rivonia Trial), which matches the timeline of returning to South Africa and facing legal consequences.
Answer:
A. arrested and imprisoned.
