Problem: Jehovah%27s Witnesses:

Rutherford centralized organizational control of the Watch Tower Society. In 1919, he instituted the appointment of a director in each congregation, and a year later all members were instructed to report their weekly preaching activity to the Brooklyn headquarters. At an international convention held at Cedar Point, Ohio, in September 1922, a new emphasis was made on house-to-house preaching. Significant changes in doctrine and administration were regularly introduced during Rutherford's twenty-five years as president, including the 1920 announcement that the Jewish patriarchs (such as Abraham and Isaac) would be resurrected in 1925, marking the beginning of Christ's thousand-year Kingdom. Disappointed by the changes, tens of thousands of defections occurred during the first half of Rutherford's tenure, leading to the formation of several Bible Student organizations independent of the Watch Tower Society, most of which still exist. By mid-1919, as many as one in seven of Russell-era Bible Students had ceased their association with the Society, and as many as two-thirds by the end of the 1920s.

In what year did the first Bible Student organizations split from the Watch Tower Society?

Problem: Next, Spielberg teamed with Star Wars creator and friend George Lucas on an action adventure film, Raiders of the Lost Ark, the first of the Indiana Jones films. The archaeologist and adventurer hero Indiana Jones was played by Harrison Ford (whom Lucas had previously cast in his Star Wars films as Han Solo). The film was considered an homage to the cliffhanger serials of the Golden Age of Hollywood. It became the biggest film at the box office in 1981, and the recipient of numerous Oscar nominations including Best Director (Spielberg's second nomination) and Best Picture (the second Spielberg film to be nominated for Best Picture). Raiders is still considered a landmark example of the action-adventure genre. The film also led to Ford's casting in Ridley Scott's Blade Runner.
What was the first Indiana Jones movie?

Answer: Raiders of the Lost Ark


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The modern Slavic peoples carry a variety of mitochondrial DNA haplogroups and Y-chromosome DNA haplogroups. Yet two paternal haplogroups predominate: R1a1a [M17] and I2a2a [L69.2=T/S163.2]. The frequency of Haplogroup R1a ranges from 63.39% in the Sorbs, through 56.4% in Poland, 54% in Ukraine, 52% in Russia, Belarus, to 15.2% in Republic of Macedonia, 14.7% in Bulgaria and 12.1% in Herzegovina. The correlation between R1a1a [M17] and the speakers of Indo-European languages, particularly those of Eastern Europe (Russian) and Central and Southern Asia, was noticed in the late 1990s. From this Spencer Wells and colleagues, following the Kurgan hypothesis, deduced that R1a1a arose on the Pontic-Caspian steppe.
What two DNA haplogroups predominate in modern Slavic peoples?
A: R1a1a [M17] and I2a2a


Context and question: The Continental Army was created on 14 June 1775 by the Continental Congress as a unified army for the colonies to fight Great Britain, with George Washington appointed as its commander. The army was initially led by men who had served in the British Army or colonial militias and who brought much of British military heritage with them. As the Revolutionary War progressed, French aid, resources, and military thinking influenced the new army. A number of European soldiers came on their own to help, such as Friedrich Wilhelm von Steuben, who taught the army Prussian tactics and organizational skills.
When did Friedrich Wilhelm von Steuben teach Prussian tactics?
Answer: unanswerable


Question: After being rendered obsolete by the redesign, the 1895 replica was presented in 1910 to the FA's long-serving president Lord Kinnaird. Kinnaird died in 1923, and his family kept it in their possession, out of view, until putting it up for auction in 2005. It was duly sold at Christie's auction house on 19 May 2005 for £420,000 (£478,400 including auction fees and taxes). The sale price set a new world record for a piece of football memorabilia, surpassing the £254,000 paid for the Jules Rimet World Cup Trophy in 1997. The successful bidder was David Gold, the then joint chairman of Birmingham City; claiming the FA and government were doing nothing proactive to ensure the trophy remained in the country, Gold stated his purchase was motivated by wanting to save it for the nation. Accordingly, Gold presented the trophy to the National Football Museum in Preston on 20 April 2006, where it went on immediate public display. It later moved with the museum to its new location in Manchester. In November 2012, it was ceremonially presented to Royal Engineers, after they beat Wanderers 7–1 in a charity replay of the first FA Cup final.
Is there an answer to this question: What year did Lord Kinnard die? 

Answer: Lord Kinnaird. Kinnaird died in 1923,


Question: Federalism is one of the entrenched constitutional principles of Germany. According to the German constitution (called Grundgesetz or in English Basic Law), some topics, such as foreign affairs and defense, are the exclusive responsibility of the federation (i.e., the federal level), while others fall under the shared authority of the states and the federation; the states retain residual legislative authority for all other areas, including "culture", which in Germany includes not only topics such as financial promotion of arts and sciences, but also most forms of education and job training. Though international relations including international treaties are primarily the responsibility of the federal level, the constituent states have certain limited powers in this area: in matters that affect them directly, the states defend their interests at the federal level through the Bundesrat (literally Federal Council, the upper house of the German Federal Parliament) and in areas where they have legislative authority they have limited powers to conclude international treaties "with the consent of the federal government".
