Suppose Nelson Mandela was an anti-apartheid revolutionary and political leader who served as President of South Africa from 1994 to 1999. He was the country's first black head of state and the first elected in a fully representative democratic election. Mandela is known for his activism and efforts to end racial segregation in South Africa.
Can we infer that "Nelson Mandela had no impact on ending racial segregation in South Africa."? Yes, no, or maybe?
