Problem: Passage: The French and Indian War (17541763) 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. Question: When was the French and Indian War?
Solution: 1754-1763
Explanation: It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. We can observe a similar notation from the passage to conclude that the French and Indian War happened during 17541763. Therefore, the answer is 17541763.

Problem: Passage: French infantry were equipped with the breech-loading Chassepot rifle, one of the most modern mass-produced firearms in the world at the time. With a rubber ring seal and a smaller bullet, the Chassepot had a maximum effective range of some 1,500 metres (4,900 ft) with a short reloading time. French tactics emphasised the defensive use of the Chassepot rifle in trench-warfare style fightingthe so-called feu de bataillon. The artillery was equipped with rifled, muzzle-loaded La Hitte guns. The army also possessed a precursor to the machine-gun: the mitrailleuse, which could unleash significant, concentrated firepower but nevertheless lacked range and was comparatively immobile, and thus prone to being easily overrun. The mitrailleuse was mounted on an artillery gun carriage and grouped in batteries in a similar fashion to cannon. Question: On what was the mitrailleuse mounted?
Solution:
on an artillery gun carriage
