Problem: Given the question: Extract the answer to the question from the following context. Question: What has been lost over almost 2 centuries? Context: High levels of precipitation cause the glaciers to descend to permafrost levels in some areas whereas in other, more arid regions, glaciers remain above about the 3,500 m (11,483 ft) level. The 1,817 square kilometres (702 sq mi) of the Alps covered by glaciers in 1876 had shrunk to 1,342 km2 (518 sq mi) by 1973, resulting in decreased river run-off levels. Forty percent of the glaciation in Austria has disappeared since 1850, and 30% of that in Switzerland.

Problem: Given the question: Extract the answer to the question from the following context. Question: What gave the sejmiks their importance? Context: In 1454 King Casimir IV granted the Nieszawa Statutes (Polish: "statuty cerkwicko-nieszawskie"), clarifying the legal basis of voivodship sejmiks (local parliaments). The king could promulgate new laws, raise taxes, or call for a levée en masse (pospolite ruszenie) only with the consent of the sejmiks, and the nobility were protected from judicial abuses. The Nieszawa Statutes also curbed the power of the magnates, as the Sejm (national parliament) received the right to elect many officials, including judges, voivods and castellans. These privileges were demanded by the szlachta as a compensation for their participation in the Thirteen Years' War.

Problem: Given the question: Extract the answer to the question from the following context. Question: Where there more or less Ashkenazi Jews as a percentage of world Jewry after the Holocaust? Context: It is estimated that in the 11th century Ashkenazi Jews composed only three percent of the world's Jewish population, while at their peak in 1931 they accounted for 92 percent of the world's Jews. Immediately prior to the Holocaust, the number of Jews in the world stood at approximately 16.7 million. Statistical figures vary for the contemporary demography of Ashkenazi Jews, oscillating between 10 million and 11.2 million. Sergio DellaPergola in a rough calculation of Sephardic and Mizrahi Jews, implies that Ashkenazi make up less than 74% of Jews worldwide. Other estimates place Ashkenazi Jews as making up about 75% of Jews worldwide.
