Suppose Nelson Mandela was a South African 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 considered a global icon for his advocacy for peace and reconciliation.
Can we infer that "Mandela was a supporter of the apartheid system in South Africa."? Yes, no, or maybe?
