 Passage 2:Koryo-saram is the name which ethnic Koreans in the Post-Soviet states use to refer to themselves. Approximately 500,000 ethnic Koreans reside in the former USSR, primarily in the newly independent states of Central Asia. There are also large Korean communities in southern Russia (around Volgograd), the Caucasus, and southern Ukraine. These communities can be traced back to the Koreans who were living in the Russian Far East during the late 19th century. There is also a separate ethnic Korean community on the island of Sakhalin, typically referred to as Sakhalin Koreans. Some may identify as Koryo-saram, but many do not. Unlike the communities on the Russian mainland, which consist mostly of immigrants from the late 19th and early 20th centuries, the ancestors of the Sakhalin Koreans came as immigrants from Gyeongsang and Jeolla provinces in the late 1930s and early 1940s, forced into service by the Japanese government to work in coal mines in order to fill labour shortages caused by World War II.
 Passage 3:Still wines from the Champagne region were known before medieval times. The Romans were the first to plant vineyards in this area of north-east France, with the region being tentatively cultivated by the 5th century. In fact, cultivation was initially slow due to the unpopular edict by Emperor Domitian that all colonial vines must be uprooted. When Emperor Probus, the son of a gardener, rescinded the edict, a temple to Bacchus was erected, and the region started to produce a red, light, and fruity wine that contrasted with heavier Italian brews often fortified with resin and herbs. Later, churches owned vineyards and monks produced wine for use in the sacrament of Eucharist. French kings were traditionally anointed in Reims, and champagne was served as part of coronation festivities. The Champenois were envious of the reputation of the wines made by their Burgundian neighbours to the south and sought to produce wines of equal acclaim. However, the northerly climate of the region gave the Champenois a unique set of challenges in making red wine. At the far extremes of sustainable viticulture, the grapes would struggle to ripen fully and often would have bracing levels of acidity and low sugar levels. The wines would be lighter bodied and thinner than the Burgundy wines they were seeking to outdo.
