One example: Passage: The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict. Question: When was the French and Indian War?
Solution is here: 1754-1763
Explanation: It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. We can observe a similar notation from the passage to conclude that the French and Indian War happened during 1754–1763. Therefore, the answer is 1754–1763.

Now, solve this: Passage: University of Massachusetts Amherst researchers estimated that from 1970 to 1996, capital flight from 30 Sub-Saharan countries totaled $187bn, exceeding those nations' external debts. (The results, expressed in retarded or suppressed development, have been modeled in theory by economist Mancur Olson.) In the case of Africa, one of the factors for this behavior was political instability, and the fact that new governments often confiscated previous government's corruptly obtained assets. This encouraged officials to stash their wealth abroad, out of reach of any future expropriation. In contrast, Asian administrations such as Suharto's New Order often took a cut on business transactions or provided conditions for development, through infrastructure investment, law and order, etc. Question: What was one of the factors for this behavior in Africa?
Solution:
political instability
