Why should the waves of Asian and African decolonization be kept distinct in timing?

Correct answer: Because regional contexts and colonial powers differed

Asian and African decolonization did not happen in one uniform sequence. Different regions had different colonial rulers, political movements, social conditions, wars, negotiations, and levels of international pressure. Some Asian countries became independent soon after the Second World War, while many African countries gained independence later, especially during the 1950s and 1960s. Even within one continent, the process could involve peaceful transfer, armed struggle, constitutional negotiation, or a mixture of these methods. A single date or simple story would therefore hide important differences.

Choice A is correct because regional contexts and colonial powers strongly influenced both timing and method. Choice B is factually false, C denies the colonial history of much of Africa, and D ignores connections between Asia, Europe, and imperial rule. A timeline is a useful study method, but it should include separate regional examples and explain why events occurred at different moments rather than treating decolonization as one simultaneous event.
