[EX Q]: Roofs are traditionally constructed from Alpine rocks such as pieces of schist, gneiss or slate. Such chalets are typically found in the higher parts of the valleys, as in the Maurienne valley in Savoy, where the amount of snow during the cold months is important. The inclination of the roof cannot exceed 40%, allowing the snow to stay on top, thereby functioning as insulation from the cold. In the lower areas where the forests are widespread, wooden tiles are traditionally used. Commonly made of Norway spruce, they are called "tavaillon". The Alpine regions are multicultural and linguistically diverse. Dialects are common, and vary from valley to valley and region to region. In the Slavic Alps alone 19 dialects have been identified. Some of the French dialects spoken in the French, Swiss and Italian alps of Aosta Valley derive from Arpitan, while the southern part of the western range is related to Old Provencal; the German dialects derive from Germanic tribal languages. Romansh, spoken by two percent of the population in southeast Switzerland, is an ancient Rhaeto-Romanic language derived from Latin, remnants of ancient Celtic languages and perhaps Etruscan.

[EX Q]: In Ukraine, Lviv and Kiev celebrated Ukrainian Independence Day on January 22, 1989. Thousands gathered in Lviv for an unauthorized moleben (religious service) in front of St. George's Cathedral. In Kiev, 60 activists met in a Kiev apartment to commemorate the proclamation of the Ukrainian People's Republic in 1918. On February 1112, 1989, the Ukrainian Language Society held its founding congress. On February 15, 1989, the formation of the Initiative Committee for the Renewal of the Ukrainian Autocephalous Orthodox Church was announced. The program and statutes of the movement were proposed by the Writers Association of Ukraine and were published in the journal Literaturna Ukraina on February 16, 1989. The organization heralded Ukrainian dissidents such as Vyacheslav Chornovil.

[EX Q]: The confusion may stem from the fact that Major League Baseball did decide that, should the Cubs make it to the World Series, the American League winner would have home field advantage unless the Cubs hosted home games at an alternate site since the Cubs home field of Wrigley Field did not yet have lights. Rumor was the Cubs could hold home games across town at Comiskey Park, home of the American League's Chicago White Sox. Rather than hold any games in the cross town rival Sox Park, the Cubs made arrangements with the August A. Busch, owner of the St. Louis Cardinals, to use Busch Stadium in St. Louis as the Cubs "home field" for the World Series. This was approved by Major League Baseball and would have enabled the Cubs to host games 1 and 2, along with games 6 and 7 if necessary. At the time home field advantage was rotated between each league. Odd numbered years the AL had home field advantage. Even numbered years the NL had home field advantage. In the 1982 World Series the St. Louis Cardinals of the NL had home field advantage. In the 1983 World Series the Baltimore Orioles of the AL had home field advantage.
[EX A]:
Why did the cubs need to host their home games at an alternative site?
