Input: Space Race
The Space Race can trace its origins to Germany, beginning in the 1930s and continuing during World War II when Nazi Germany researched and built operational ballistic missiles. Starting in the early 1930s, during the last stages of the Weimar Republic, German aerospace engineers experimented with liquid-fueled rockets, with the goal that one day they would be capable of reaching high altitudes and traversing long distances. The head of the German Army's Ballistics and Munitions Branch, Lieutenant Colonel Karl Emil Becker, gathered a small team of engineers that included Walter Dornberger and Leo Zanssen, to figure out how to use rockets as long-range artillery in order to get around the Treaty of Versailles' ban on research and development of long-range cannons. Wernher von Braun, a young engineering prodigy, was recruited by Becker and Dornberger to join their secret army program at Kummersdorf-West in 1932. Von Braun had dreams about conquering outer space with rockets, and did not initially see the military value in missile technology.

What were German aerospace engineers experimenting with in the 1930's?
Output: liquid-fueled rockets

Input: Article: The subsequent 2005 elections were internationally regarded as the most free and fair in Liberian history. Ellen Johnson Sirleaf, a Harvard-trained economist and former Minister of Finance, was elected as the first female president in Africa. Upon her inauguration, Sirleaf requested the extradition of Taylor from Nigeria and transferred him to the SCSL for trial in The Hague. In 2006, the government established a Truth and Reconciliation Commission to address the causes and crimes of the civil war.

Now answer this question: The 2005 elections were known as what?

Output: the most free and fair in Liberian history

Article: The waterwheel appeared in Chinese records during the Han. As mentioned by Huan Tan in about 20 AD, they were used to turn gears that lifted iron trip hammers, and were used in pounding, threshing and polishing grain. However, there is no sufficient evidence for the watermill in China until about the 5th century. The Nanyang Commandery Administrator Du Shi (d. 38 AD) created a waterwheel-powered reciprocator that worked the bellows for the smelting of iron. Waterwheels were also used to power chain pumps that lifted water to raised irrigation ditches. The chain pump was first mentioned in China by the philosopher Wang Chong in his 1st-century-AD Balanced Discourse.

Question: During what century is it likely that the watermill made an appearance in China?
Ans: about the 5th century

Here is a question about this article: Most of the differences in the revised budget deficit numbers were due to a temporary change of accounting practices by the new government, i.e., recording expenses when military material was ordered rather than received. However, it was the retroactive application of ESA95 methodology (applied since 2000) by Eurostat, that finally raised the reference year (1999) budget deficit to 3.38% of GDP, thus exceeding the 3% limit. This led to claims that Greece (similar claims have been made about other European countries like Italy) had not actually met all five accession criteria, and the common perception that Greece entered the Eurozone through "falsified" deficit numbers.
What is the answer to this question: What other European country were claims similar to those levied against Greece made?
****
So... Italy

Everton's biggest rivalry is with neighbours Liverpool, against whom they contest the Merseyside derby. The Merseyside derby is usually a sellout fixture, and has been known as the "friendly derby" because both sets of fans can often be seen side by side red and blue inside the stadium both at Anfield and Goodison Park. Recently on the field, matches tend to be extremely stormy affairs; the derby has had more red cards than any other fixture in Premiership history. The rivalry stems from an internal dispute between Everton officials and the owners of Anfield, which was then Everton's home ground, resulting in Everton moving to Goodison Park, and the subsequent formation of Liverpool F.C., in 1892.
Where did Everton FC move to that began their rivalry with Liverpool?
****
The answer: Goodison Park

The problem: Answer a question about this article:
Portugal's colonial history has long since been a cornerstone of its national identity, as has its geographic position at the south-western corner of Europe, looking out into the Atlantic Ocean. It was one of the last western colonial European powers to give up its overseas territories (among them Angola and Mozambique in 1975), turning over the administration of Macau to the People's Republic of China at the end of 1999. Consequently, it has both influenced and been influenced by cultures from former colonies or dependencies, resulting in immigration from these former territories for both economic and/or personal reasons. Portugal, long a country of emigration (the vast majority of Brazilians have Portuguese ancestry), has now become a country of net immigration, and not just from the last Indian (Portuguese until 1961), African (Portuguese until 1975), and Far East Asian (Portuguese until 1999) overseas territories. An estimated 800,000 Portuguese returned to Portugal as the country's African possessions gained independence in 1975. By 2007, Portugal had 10,617,575 inhabitants of whom about 332,137 were legal immigrants.
How many inhabitants did Portugal have by 2007?
****
The answer:
10,617,575
