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: Leading up to the American Civil War, Baptists became embroiled in the controversy over slavery in the United States. Whereas in the First Great Awakening, Methodist and Baptist preachers had opposed slavery and urged manumission, over the decades they made more of an accommodation with the institution. They worked with slaveholders in the South to urge a paternalistic institution. Both denominations made direct appeals to slaves and free blacks for conversion. The Baptists particularly allowed them active roles in congregations. By the mid-19th century, northern Baptists tended to oppose slavery. As tensions increased, in 1844 the Home Mission Society refused to appoint a slaveholder as a missionary who had been proposed by Georgia. It noted that missionaries could not take servants with them, and also that the Board did not want to appear to condone slavery.
Solution:
When did Baptists become embroiled in the controversy over slavery in the United States?
