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.
Example solution: When was the French and Indian War?
Example explanation: 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.

Problem: Because rebroadcast transmitters were not planned to be converted to digital, many markets stood to lose over-the-air coverage from CBC or Radio-Canada, or both. As a result, only seven of the markets subject to the August 31, 2011 transition deadline were planned to have both CBC and Radio-Canada in digital, and 13 other markets were planned to have either CBC or Radio-Canada in digital. In mid-August 2011, the CRTC granted the CBC an extension, until August 31, 2012, to continue operating its analogue transmitters in markets subject to the August 31, 2011 transition deadline. This CRTC decision prevented many markets subject to the transition deadline from losing signals for CBC or Radio-Canada, or both at the transition deadline. At the transition deadline, Barrie, Ontario lost both CBC and Radio-Canada signals as the CBC did not request that the CRTC allow these transmitters to continue operating.
Solution: When was CBC's anologue upgrade extension set to expire?
