Final answer:
Nineteen years before Ishmael Beah's birth, Sierra Leone declared independence from British colonial rule on April 27, 1961.
Step-by-step explanation:
Nineteen years before Ishmael Beah was born, as mentioned in his memoir A Long Way Gone: Memoirs of a Boy Soldier, Sierra Leone declared independence. This event took place on April 27, 1961, and is a significant point in the country's history as it marked the end of British colonial rule. The process of decolonization in Africa was often accompanied by significant struggles, including civil wars and political instability as newly independent nations attempted to establish governance and bring together diverse peoples and regions under a single national identity. In his memoir "A Long Way Gone: Memoirs of a Boy Soldier," Ishmael Beah mentions that the Sierra Leone Civil War began nineteen years before he was born. This means that option B) The Sierra Leone Civil War began is the correct answer choice.
