[EX Q]: Question: When was the town Ottwalt lived in while writing for an exile magazine founded? Passage:In 1933, Ottwalt and his wife, Waltraut, left Germany and went into exile in Denmark, then, by way of Czechoslovakia, ended up in the Soviet Union. Living in Moscow, Ottwalt wrote for the German exile magazine Internationale Literatur (published by Johannes R. Becher) and was an editor at Vegaar Bibliothek. He also wrote for the Deutsche Zentral Zeitung. In 1936, he and his wife were ensnared in the Stalinist purges and arrested by the Soviet secret police, the NKVD. He was charged with suspicion of espionage, sentenced to forced labor and deported to a gulag near Archangelsk. His wife was sentenced to forced labor in Kotlas. She was deported back to Germany in January 1941 and didn't learn about his death until January 1958, when the Soviet Red Cross informed her that her husband had died on 24 August 1943.

[EX Q]: Question: Did the chief who predicted the massacre of Mormon towns survive the Black Hawk War? Passage:The Navajo War was not directly a part of the Black Hawk War, but it may have been a source of some of the native warriors who fought in the Black Hawk War. Black Hawk's success drew fighters from other Utes in Colorado, Apaches from New Mexico, and many Navajos. In the winter of 1866 Black Hawk and his band went to the Four Corners region where he received many new recruits. So many Navajos joined him that they formed almost half his raiders. The Navajo had been decimated by the U.S. Army under Kit Carson and forced out of their ancestral homeland. The remaining Navajos were eager for a chance to build up their herds at the expense of white settlers. Manuelito, the most important chief refusing to relocate to the Bosque Redondo Reservation, jointly led Black Hawk's raids on Mormon settlements in southern Utah during 1866. The attacks commenced at Pipe Springs, then a Mormon settlement on the Arizona-Utah border. The retaliation for the Pipe Springs raid left four unarmed Paiutes dead for murders they had nothing to do with. This brought some Paiute fighters to Black Hawk's band. Hopis hearing of the Navajo's movements feared they were to be attacked and struck first ambushing Manuelito's Navajos. The raids continued at the Paria settlements, and Kanab, who sent pleas for help against the raids. In subsequent years, the raids continued in the south by Navajos and Paiutes, which raised tensions to a fever pitch which would result in the worst massacre of the war at Circleville. Chief Kanosh predicted that in 1867 six thousand Navajos would wipe out the Mormon towns in southern Utah.

[EX Q]: Question: How many years were between the end of the Emperor's reign who called for all colonial vines to be uprooted and the beginning of the reign where the son of a gardener rescinded the edict? Passage: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.
