[EX Q]: Passage: Over the centuries, Weimar remained a small town of less than 5,000 inhabitants. When it became the capital of Saxe-Weimar in 1572, population growth was stimulated and population increased from 3,000 in 1650 to 6,000 in 1750. Around the year 1800, Weimar had 7,000 inhabitants. Their number grew constantly over the years to 13,000 in 1850, 28,000 in 1900 and 35,000 at the beginning of World War I. During the interwar period, the new capital of Thuringia saw a population boom, which led to 65,000 inhabitants in 1940. Since that time, the population levels have stagnated. The years 2009 to 2012 brought a moderate growth of approximately 0.35% p. a., whereas the population in bordering rural regions is shrinking with accelerating tendency. Suburbanization played only a small role in Weimar. It occurred after the reunification for a short time in the 1990s, but most of the suburban areas were situated within the administrative city borders.
Question: Which year were there more people living in Weimar, 1850 or 1900?
[EX A]: date

[EX Q]: Passage: Throughout its existence, Warsaw has been a multi-cultural city. According to the 1901 census, out of 711,988 inhabitants 56.2% were Catholics, 35.7% Jews, 5% Greek Orthodox Christians and 2.8% Protestants. Eight years later, in 1909, there were 281,754 Jews (36.9%), 18,189 Protestants (2.4%) and 2,818 Mariavite Church (0.4%). This led to construction of hundreds of places of religious worship in all parts of the town. Most of them were destroyed in the aftermath of the Warsaw uprising of 1944. After the war, the new communist authorities of Poland discouraged church construction and only a small number were rebuilt.
Question: Which year saw a higher amount of Jews in the population, 1901 or 1909?

[EX Q]: Passage: Theobald I of Lorraine died in May 1220 under mysterious circumstances, and to seal the peace the 19-year-old Theobald IV of Champagne married Lorraine's 16-year-old widow, Gertrude of Dagsburg.  Duke Theobald I's brother Matthew II, who succeeded in Lorraine, made peace and swore fealty to Blanche.  Bishop William of Langres was elected archbishop of Reims in 1219, resulting in his fortuitous departure from the conflict.  Erard renounced any claim on Champagne on 2 November 1221 and Philippa in April 1222.  In return for renouncing his claims, Erard received a substantial cash settlement.  The last rebel baron, Erard II of Chacernay, swore his renewed loyalty to Theobald IV in March 1222.  Two months later in May 1222, Theobald IV reached the age of maturity and began his reign as count, and the triumphant Countess-Regent Blanche withdrew to the Cistercian convent of Argensolles for her retirement.
