One example: Passage: The French and Indian War (17541763) 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 17541763. Therefore, the answer is 17541763.

Now, solve this: Passage: The administration of justice was of particular importance to John. Several new processes had been introduced to English law under Henry II, including novel disseisin and mort d'ancestor. These processes meant the royal courts had a more significant role in local law cases, which had previously been dealt with only by regional or local lords. John increased the professionalism of local sergeants and bailiffs, and extended the system of coroners first introduced by Hubert Walter in 1194, creating a new class of borough coroners. John worked extremely hard to ensure that this system operated well, through judges he had appointed, by fostering legal specialists and expertise, and by intervening in cases himself. John continued to try relatively minor cases, even during military crises. Viewed positively, Lewis Warren considers that John discharged "his royal duty of providing justice ... with a zeal and a tirelessness to which the English common law is greatly endebted". Seen more critically, John may have been motivated by the potential of the royal legal process to raise fees, rather than a desire to deliver simple justice; John's legal system also only applied to free men, rather than to all of the population. Nonetheless, these changes were popular with many free tenants, who acquired a more reliable legal system that could bypass the barons, against whom such cases were often brought. John's reforms were less popular with the barons themselves, especially as they remained subject to arbitrary and frequently vindictive royal justice. Question: When was the system of coroners first introduced?
Solution:
1194
