Input: The East Asia/Pacific region has reached its goals on nutrition, in part due to the improvements contributed by China, the region's most populous country. China has reduced its underweight prevalence from 19 percent to 8 percent between 1990 and 2002. China played the largest role in the world in decreasing the rate of children under five underweight between 1990 and 2004, halving the prevalence. This reduction of underweight prevalence has aided in the lowering of the under 5 mortality rate from 49 to 31 of 1000. They also have a low birthweight rate at 4%, a rate comparable to industrialized countries, and over 90% of households receive adequate iodized salts. However, large disparities exist between children in rural and urban areas, where 5 provinces in China leave 1.5 million children iodine deficient and susceptible to diseases. Singapore, Vietnam, Malaysia, and Indonesia are all projected to reach nutrition MDGs. Singapore has the lowest under five mortality rate of any nation, besides Iceland, in the world, at 3%. Cambodia has the highest rate of child mortality in the region (141 per 1,000 live births), while still its proportion of underweight children increased by 5 percent to 45% in 2000. Further nutrient indicators show that only 12 per cent of Cambodian babies are exclusively breastfed and only 14 per cent of households consume iodized salt.

Question: How many years did it take for China to reduce its underweight prevalence from 19 to 8?

Input: Further to the west, the Suez Canal was defended from Ottoman attacks in 1915 and 1916; in August, a German and Ottoman force was defeated at the Battle of Romani by the ANZAC Mounted Division and the 52nd Infantry Division. Following this victory, an Egyptian Expeditionary Force advanced across the Sinai Peninsula, pushing Ottoman forces back in the Battle of Magdhaba in December and the Battle of Rafa on the border between the Egyptian Sinai and Ottoman Palestine in January 1917. Russian armies generally had success in the Caucasus. Enver Pasha, supreme commander of the Ottoman armed forces, was ambitious and dreamed of re-conquering central Asia and areas that had been lost to Russia previously. He was, however, a poor commander. He launched an offensive against the Russians in the Caucasus in December 1914 with 100,000 troops, insisting on a frontal attack against mountainous Russian positions in winter. He lost 86% of his force at the Battle of Sarikamish.

Question: Which came first, the Battle of Magdhaba or the Battle of Rafa?

Input: As of the census of 2010, there were 47,723 people, 17,816 households, and 11,722 families residing in the city. The population density was 1,754.6/sq mi (677.5/km). There were 19,806 housing units at an average density of 749.9 per square mile (289.6/km). The racial makeup of the city was 38.32% White (U.S. Census), 57.25% African American (U.S. Census), 1.25% Native American (U.S. Census), 1.85% Asian, 0.14% Pacific Islander (U.S. Census), 1.03% from Race (United States Census), and 1.09% from two or more races. 6.98% of the population were Hispanics in the United States or Latino (U.S. Census) of any race.

Question: Which groups had more than 25% of the population each?

Input: After long negotiations the territorial changes resulting from the conflict were firmly established at the Treaty of Quedlinburg of 13 May 1523. The main import of these changes were significant gains for the princes of Brunswick-Wolfenbuttel, whilst the Prince-Bishopric of Hildesheim was left with just 4 of its original 22 districts as well as the towns of Hildesheim and Peine, the so-called Kleines Stift of some 90 villages. The ecclesiastical boundary of the diocese remained unchanged. The Principality of Brunswick-Wolfenbuttel was awarded the Amter of Winzenburg, Wohldenberg, Steinbruck, Lutter, Wohlenstein, Schladen, Liebenburg, Wiedelah, Vienenburg and Westerhof with the abbeys of Lamspringe, Heiningen, Dorstadt, Woltingerode, Ringelheim and Riechenberg, as well as the towns of Alfeld, Bockenem, Lamspringe and Salzgitter. The Principality of Calenberg received the houses, i.e.fortified seats, and Amter of Hunnesruck with Markoldendorf, Aerzen, Lauenstein, Grohnde, Hallerburg, Poppenburg, Ruthe and Coldingen, the towns of Dassel, Bodenwerder, Gronau, Elze, Sarstedt, half of Hameln and the abbeys of Marienau, Escherde, Wittenburg, Wulfinghausen and Derneburg. Hildesheim immediately began a legal fight for the return of its Groes Stift . This finally ended in 1643 in the Main Treaty of Hildesheim with a revision of the Treaty of Quedlinburg and return of most of the territories. Exceptions were the Amter of Aerzen, Grohnde, Coldingen-Lauenberg, Lutter am Barenberge, Westerhof and Lindau, which remained with the principalities of Calenberg and Brunswick-Wolfenbuttel. Prince-bishop John IV gave up the prince-bishopric in 1527 and later became canon of Ratzeburg and died in 1547 in Lubeck.

Question:
How many districts did the Principality of Brunswick-Wolfenbuttel and the Principality of Calenberg each recieve?
