P: The total population in sub-Saharan Africa is projected to increase to almost one billion people, making it the most populated region outside of South-Central Asia. According to the United Nations, the population of Nigeria will reach 411 million by 2050. Nigeria might then be the 3rd most populous country in the world. In 2100, the population of Nigeria may reach 794 million. While the overall population is expected to increase, the growth rate is estimated to decrease from 1.2 percent per year in 2010 to 0.4 percent per year in 2050. The birth rate is also projected to decrease from 20.7 to 13.7, while the death rate is projected to increase from 8.5 in 2010 to 9.8 in 2050. List of countries by life expectancy is all expected to increase from 67.0 years in 2010 to 75.2 years in 2050. By 2050 the percent of the population estimated to be living in urban areas is 69.6% compared to the 50.6% in 2010.
Answer this: By how many people ist he death rate projected to increase between 2010 and 2050?

Problem: Before the Nazi era Franconia was as a region with significant Jewish communities, most of whom were Ashkenazi Jews. The first Jewish communities appeared in Franconia in the 12th and 13th centuries and thus later than, for example, in Regensburg. In the Middle Ages, Franconia was a stronghold of Torah studies. But Franconia also began to exclude the Jewish populations particularly early on. For example, there were two Jewish massacres - the Rintfleisch massacres of 1298 and the Armleder Uprising of 1336-1338 - and in the 15th and 16th centuries many cities exiled their Jewish populations, which is why many Jews settled in rural communities. Franconia also rose to early prominence in the discrimination of Jews during the Nazi era. One of the first casualties of the organized Nazi persecution of Jews took place on 21 March in Künzelsau and on 25/26 March 1933 in Creglingen, where police and SA troops under the leadership of Standartenführer Fritz Klein led a so-called "weapons search operations".Whilst, in 1818, about 65 per cent of Bavarian Jews lived in the Bavarian part of Franconia, today there are only Jewish communities in Bamberg, Bayreuth, Erlangen, Fürth, Hof, Nuremberg and Würzburg and in Heilbronn in Baden-Württemberg.

What was the name of the first Jewish massacres in Regensburg?
Answer: Rintfleisch massacre
Q: Coming off their win over the Giants the Eagles flew to Soldier Field for an NFC duel with the Bears. The Eagles had the early advantage with kicker David Akers nailing a 45-yard field goal. It soon disappeared after QB Jay Cutler completed a 10 and a 20-yard TD pass to wide receivers Earl Bennett and Johnny Knox respectively. The Eagles tried to cut the lead with QB Michael Vick getting an 8-yard TD pass to WR Jeremy Maclin, followed by Akers hitting a 36-yard field goal. But they fell further behind as Cutler got a 6 and a 9-yard TD pass to Bennett and Greg Olsen. This was followed by kicker Robbie Gould making a 23-yard field goal. The Eagles tried to narrow the lead as Akers got a 22 and a 36-yard field goal, followed by Vick throwing a 30-yard TD pass to TE Brent Celek, but the Bears' defense prevented any more scoring chances.
How many less is the 22 yard goal compared to the 45 yard goal?
A: 23
Problem: The fortifications of Mdina  are a series of defensive walls which surround the former capital city of Mdina, Malta. The city was founded as Maleth by the Phoenicians in around the 8th century BC, and it later became part of the Roman Empire under the name Melite. The ancient city was surrounded by walls, but very few remains of these have survived. The city walls were rebuilt a number of times, including by the Byzantine Empire in around the 8th century AD, the Arabs in around the 11th century, and the Kingdom of Sicily in the medieval period until the 15th century. Most of the extant fortifications were built by the Order of Saint John between the 16th and 18th centuries. The city has withstood a number of sieges, and it was defeated twice - first by the Aghlabids in 870 and then by Maltese rebels in 1798. Today, the city walls are still intact except for some outworks, and they are among the best preserved fortifications in Malta. Mdina has been on Malta's tentative list of UNESCO World Heritage Sites since 1998.
Answer this question based on the article: How many years passed between the first and second defeats of Mdina?
A: 928
P: On 11 November, at 5:00 am, an armistice with Germany was signed in a railroad carriage at Compiègne. At 11 am on 11 November 1918—"the eleventh hour of the eleventh day of the eleventh month"—a ceasefire came into effect. During the six hours between the signing of the armistice and its taking effect, opposing armies on the Western Front began to withdraw from their positions, but fighting continued along many areas of the front, as commanders wanted to capture territory before the war ended. The occupation of the Rhineland took place following the Armistice. The occupying armies consisted of American, Belgian, British and French forces. In November 1918, the Allies had ample supplies of men and materiel to invade Germany. Yet at the time of the armistice, no Allied force had crossed the German frontier, the Western Front was still some 720 kilometres  from Berlin, and the Kaiser's armies had retreated from the battlefield in good order. These factors enabled Hindenburg and other senior German leaders to spread the story that their armies had not really been defeated. This resulted in the stab-in-the-back legend, which attributed Germany's defeat not to its inability to continue fighting , but to the public's failure to respond to its "patriotic calling" and the supposed intentional sabotage of the war effort, particularly by Jews, Socialists, and Bolsheviks. The Allies had much more potential wealth they could spend on the war. One estimate  is that the Allies spent $58 billion on the war and the Central Powers only $25 billion. Among the Allies, the UK spent $21 billion and the US $17 billion; among the Central Powers Germany spent $20 billion.
Answer this: How many billion dollars did the UK and the US spend combined according to one estimate?

A:
38
