Input: Consider Input: Passage: Prior to Confederation in 1867, residents of the colonies in what is now Canada served as regular members of French and British forces and in local militia groups. The latter aided in the defence of their respective territories against attacks by other European powers, Aboriginal peoples, and later American forces during the American Revolutionary War and War of 1812, as well as in the Fenian raids, Red River Rebellion, and North-West Rebellion. Consequently, the lineages of some Canadian army units stretch back to the early 19th century, when militia units were formed to assist in the defence of British North America against invasion by the United States. Question: The forces of what countries did people serve before the unification?

Output: French and British forces


Input: Consider Input: Passage: The "snug", sometimes called the smoke room, was typically a small, very private room with access to the bar that had a frosted glass external window, set above head height. A higher price was paid for beer in the snug and nobody could look in and see the drinkers. It was not only the wealthy visitors who would use these rooms. The snug was for patrons who preferred not to be seen in the public bar. Ladies would often enjoy a private drink in the snug in a time when it was frowned upon for women to be in a pub. The local police officer might nip in for a quiet pint, the parish priest for his evening whisky, or lovers for a rendezvous. Question: What was the relationship between the price of beer in the smoke room versus the rest of the bar?

Output: higher

Question: Who were the beneficiaries of his last public concert?
