A: Lahore

Q: Extract the answer to the question from the following context. Question: What coverts water into electricity for europeans? Context: The Alps provide lowland Europe with drinking water, irrigation, and hydroelectric power. Although the area is only about 11 percent of the surface area of Europe, the Alps provide up to 90 percent of water to lowland Europe, particularly to arid areas and during the summer months. Cities such as Milan depend on 80 percent of water from Alpine runoff. Water from the rivers is used in over 500 hydroelectricity power plants, generating as much as 2900 kilowatts of electricity.
A: 500 hydroelectricity power plants

Q: Extract the answer to the question from the following context. Question: Before being acculturated what often happened? Context: For centuries, various peoples in modern-day Nigeria traded overland with traders from North Africa. Cities in the area became regional centres in a broad network of trade routes that spanned western, central and northern Africa. In the 16th century, Spanish and Portuguese explorers were the first Europeans to begin significant, direct trade with peoples of modern-day Nigeria, at the port they named Lagos and in Calabar. Europeans traded goods with peoples at the coast; coastal trade with Europeans also marked the beginnings of the Atlantic slave trade. The port of Calabar on the historical Bight of Biafra (now commonly referred to as the Bight of Bonny) become one of the largest slave trading posts in West Africa in the era of the transatlantic slave trade. Other major slaving ports in Nigeria were located in Badagry, Lagos on the Bight of Benin and on Bonny Island on the Bight of Biafra. The majority of those enslaved and taken to these ports were captured in raids and wars. Usually the captives were taken back to the conquerors' territory as forced labour; after time, they were sometimes acculturated and absorbed into the conquerors' society. A number of slave routes were established throughout Nigeria linking the hinterland areas with the major coastal ports. Some of the more prolific slave traders were linked with the Oyo Empire in the southwest, the Aro Confederacy in the southeast and the Sokoto Caliphate in the north.
A: forced labour

Q: Extract the answer to the question from the following context. Question: What representation do the DNA samples from the Russians have in the total pool? Context: DNA samples from 1228 Russians show that the Y chromosomes analyzed, all except 20 (1.6%) fall into seven major haplogroups all characteristic to West Eurasian populations. Taken together, they account for 95% of the total Russian Y chromosomal pool. Only (0.7%) fell into haplogroups that are specific to East and South Asian populations. Mitochondrial DNA (mtDNA) examined in Poles and Russians revealed the presence of all major European haplogroups, which were characterized by similar patterns of distribution in Poles and Russians. An analysis of the DNA did not reveal any specific combinations of unique mtDNA haplotypes and their subclusters. The DNA clearly shows that both Poles and Russians are not different from the neighbouring European populations.
A:
they account for 95% of the total Russian Y chromosomal pool
