Input: Consider Input: Passage: In the last two decades of the 18th century, the theory of polygenism, the belief that different races had evolved separately in each continent and shared no common ancestor, was advocated in England by historian Edward Long and anatomist Charles White, in Germany by ethnographers Christoph Meiners and Georg Forster, and in France by Julien-Joseph Virey. In the US, Samuel George Morton, Josiah Nott and Louis Agassiz promoted this theory in the mid-nineteenth century. Polygenism was popular and most widespread in the 19th century, culminating in the founding of the Anthropological Society of London (1863) during the period of the American Civil War, in opposition to the Ethnological Society, which had abolitionist sympathies. Question: In what century was polygenism most widespread?

Output: 19th century

Input: Consider Input: Passage: The Partyja BPF (Belarusian Popular Front) was established in 1988 as a political party and cultural movement for democracy and independence, a la the Baltic republics' popular fronts. The discovery of mass graves in Kurapaty outside Minsk by historian Zianon Pazniak, the Belarusian Popular Front's first leader, gave additional momentum to the pro-democracy and pro-independence movement in Belarus. It claimed that the NKVD performed secret killings in Kurapaty. Initially the Front had significant visibility because its numerous public actions almost always ended in clashes with the police and the KGB. Question: Where were the graves found?
Output: Kurapaty
