question: The Battle of Stamford Bridge took place at the village of Stamford Bridge, East Riding of Yorkshire, in England on 25 September 1066, between an English army under King Harold Godwinson and an invading Norwegian force led by King Harald Hardrada and the English king's brother Tostig Godwinson. After a bloody battle, both Hardrada and Tostig along with most of the Norwegians were killed. Although Harold Godwinson repelled the Norwegian invaders, his army was defeated by the Normans at Hastings less than three weeks later. The battle has traditionally been presented as symbolising the end of the Viking Age, although major Scandinavian campaigns in Britain and Ireland occurred in the following decades, such as those of King Sweyn Estrithson of Denmark in 1069-1070 and King Magnus Barefoot of Norway in 1098 and 1102-1103.
Answer this question: Which commanders died during battle against the English Army?
answer: Hardrada

question: As early as 1070, Adam von Bremen referred to Roskilde as "Zealands largest town". At the time of the Reformation in 1536, it had some 6,000 inhabitants but as a result of war, fire and disease, by 1753 its population had dropped to only 1,550. By the 1860s, it had grown to around 5,000 and by the 1900s to some 9,000. Thereafter it increased appreciably until 1970 when there were almost 45,000 inhabitants. The population dipped slightly to 40,000 in the 1980s, but thanks to improved connections with Copenhagen and the establishment of the university, it grew steadily to reach 47,117 by 2014 making Roskilde Denmarks tenth largest city.
Answer this question: How many less inhabitants by 1753 in Roskilde than in 1536?
answer: 217

question: The minimum wage, public-sector wages, and old-age pensions are routinely raised twice a year to ensure that base income is not eroded by inflation. Although no statistics are published on average wages in Uzbekistan, pensions as a proxy for the average wage increased significantly between 1995 and 2006, both in real terms and in U.S. dollars. The monthly old-age pension increased in real (CPI-adjusted) sums by almost a factor of 5 between 1995 and 2006. The monthly pension in U.S. dollars was around $20$25 until 2000, then dropped to $15$20 between 2001 and 2004, and now is $64. The minimum wage was raised to $34.31 in November 2011. Assuming that the average wages in the country are at a level of 3-4 times the monthly pension, we estimate the wages in 2006 at $100$250 per month, or $3$8 per day.
Answer this question: How many dollars did the monthly pension drop between 2001 and 2004?
answer:
5
