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.
Solution is here: When was the French and Indian War?
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.

Now, solve this: Also of major note in Ciudad Vieja is the Plaza de la Constitución (or Plaza Matriz). During the first decades of Uruguayan independence this square was the main hub of city life. On the square are the Cabildo—the seat of colonial government—and the Montevideo Metropolitan Cathedral. The cathedral is the burial place of Fructuoso Rivera, Juan Antonio Lavalleja and Venancio Flores. Another notable square is Plaza Zabala with the equestrian statue of Bruno Mauricio de Zabala. On its south side, Palacio Taranco, once residence of the Ortiz Taranco brothers, is now the Museum of Decorative Arts. A few blocks northwest of Plaza Zabala is the Mercado del Puerto, another major tourist destination.
