Let me give you an 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.
The answer to this example can be: When was the French and Indian War?
Here is why: 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.

OK. solve this:
Miami's road system is based along the numerical "Miami Grid" where Flagler Street forms the east-west baseline and Miami Avenue forms the north-south meridian. The corner of Flagler Street and Miami Avenue is in the middle of Downtown in front of the Downtown Macy's (formerly the Burdine's headquarters). The Miami grid is primarily numerical so that, for example, all street addresses north of Flagler Street and west of Miami Avenue have "NW" in their address. Because its point of origin is in Downtown, which is close to the coast, therefore, the "NW" and "SW" quadrants are much larger than the "SE" and "NE" quadrants. Many roads, especially major ones, are also named (e.g., Tamiami Trail/SW 8th St), although, with exceptions, the number is in more common usage among locals.
Answer:
What company was previously headquartered in the Downtown Macy's?
