Input: Richmond, Virginia
Much of Richmond's early architecture was destroyed by the Evacuation Fire in 1865. It is estimated that 25% of all buildings in Richmond were destroyed during this fire. Even fewer now remain due to construction and demolition that has taken place since Reconstruction. In spite of this, Richmond contains many historically significant buildings and districts. Buildings remain from Richmond's colonial period, such as the Patteson-Schutte House and the Edgar Allan Poe Museum (Richmond, Virginia), both built before 1750.

What disaster destroyed many of the early buildings in Richmond?
Output: Evacuation Fire

Input: Royal assent
In Belgium, the sanction royale has the same legal effect as royal assent; the Belgian constitution requires a theoretically possible refusal of royal sanction to be countersigned—as any other act of the monarch—by a minister responsible before the House of Representatives. The monarch promulgates the law, meaning that he or she formally orders that the law be officially published and executed. In 1990, when King Baudouin advised his cabinet he could not, in conscience, sign a bill decriminalising abortion (a refusal patently not covered by a responsible minister), the Council of Ministers, at the King's own request, declared Baudouin incapable of exercising his powers. In accordance with the Belgian constitution, upon the declaration of the sovereign's incapacity, the Council of Ministers assumed the powers of the head of state until parliament could rule on the King's incapacity and appoint a regent. The bill was then assented to by all members of the Council of Ministers "on behalf of the Belgian People". In a joint meeting, both houses of parliament declared the King capable of exercising his powers again the next day.

Which King refused to sign an abortion decriminalization bill in 1990?
Output: King Baudouin

Input: Alfred North Whitehead
At the time structures such as Lie algebras and hyperbolic quaternions drew attention to the need to expand algebraic structures beyond the associatively multiplicative class. In a review Alexander Macfarlane wrote: "The main idea of the work is not unification of the several methods, nor generalization of ordinary algebra so as to include them, but rather the comparative study of their several structures." In a separate review, G. B. Mathews wrote, "It possesses a unity of design which is really remarkable, considering the variety of its themes."

How did Alexander Macfarlane summarize the relationship between different methods in "A Treatise on Algebra" in his review?
Output: comparative study of their several structures

Input: Premier League
Despite significant European success during the 1970s and early 1980s, the late '80s had marked a low point for English football. Stadiums were crumbling, supporters endured poor facilities, hooliganism was rife, and English clubs were banned from European competition for five years following the Heysel Stadium disaster in 1985. The Football League First Division, which had been the top level of English football since 1888, was well behind leagues such as Italy's Serie A and Spain's La Liga in attendances and revenues, and several top English players had moved abroad.

Why were the English clubs banned from European competition in the 1980's?
Output:
English clubs were banned from European competition for five years following the Heysel Stadium disaster in 1985.
