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.
Solution: When was the French and Indian War?
Reason: This question is based on the following sentence in the passage- The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. You can ask questions like this one about dates, years, other numerals, persons, locations, noun phrases, verb phrases, adjectives, clauses etc. which exist in the paragraph.

Now, solve this instance: From the end of World War I until 1962, New Zealand controlled Samoa as a Class C Mandate under trusteeship through the League of Nations, then through the United Nations. There followed a series of New Zealand administrators who were responsible for two major incidents. In the first incident, approximately one fifth of the Samoan population died in the influenza epidemic of 1918–1919. Between 1919 and 1962, Samoa was administered by the Department of External Affairs, a government department which had been specially created to oversee New Zealand's Island Territories and Samoa. In 1943, this Department was renamed the Department of Island Territories after a separate Department of External Affairs was created to conduct New Zealand's foreign affairs.
