Problem: Hanover:

After 1937 the Lord Mayor and the state commissioners of Hanover were members of the NSDAP (Nazi party). A large Jewish population then existed in Hanover. In October 1938, 484 Hanoverian Jews of Polish origin were expelled to Poland, including the Grynszpan family. However, Poland refused to accept them, leaving them stranded at the border with thousands of other Polish-Jewish deportees, fed only intermittently by the Polish Red Cross and Jewish welfare organisations. The Gryszpan's son Herschel Grynszpan was in Paris at the time. When he learned of what was happening, he drove to the German embassy in Paris and shot the German diplomat Eduard Ernst vom Rath, who died shortly afterwards.

How many Hanoverian Jews were sent to Paris?

A: unanswerable

Problem: American Idol is broadcast to over 100 nations outside of the United States. In most nations these are not live broadcasts and may be tape delayed by several days or weeks. In Canada, the first thirteen seasons of American Idol were aired live by CTV and/or CTV Two, in simulcast with Fox. CTV dropped Idol after its thirteenth season and in August 2014, Yes TV announced that it had picked up Canadian rights to American Idol beginning in its 2015 season.
Who stated in August 2014 that they picked up the rights beginning in its 2015 season?

Answer: Yes TV

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Although the Tories were dismissed from office for half a century, for most of this period (at first under the leadership of Sir William Wyndham), the Tories retained party cohesion, with occasional hopes of regaining office, particularly at the accession of George II (1727) and the downfall of the ministry of Sir Robert Walpole in 1742. They acted as a united, though unavailing, opposition to Whig corruption and scandals. At times they cooperated with the "Opposition Whigs", Whigs who were in opposition to the Whig government; however, the ideological gap between the Tories and the Opposition Whigs prevented them from coalescing as a single party. They finally regained power with the accession of George III in 1760 under Lord Bute.
Who did the Tories occasionally cooperate with?
A: the "Opposition Whigs"

Context and question: Research seems to favor the hypothesis that adolescents and adults think about risk in similar ways, but hold different values and thus come to different conclusions. Some have argued that there may be evolutionary benefits to an increased propensity for risk-taking in adolescence. For example, without a willingness to take risks, teenagers would not have the motivation or confidence necessary to leave their family of origin. In addition, from a population perspective, there is an advantage to having a group of individuals willing to take more risks and try new methods, counterbalancing the more conservative elements more typical of the received knowledge held by older adults. Risktaking may also have reproductive advantages: adolescents have a newfound priority in sexual attraction and dating, and risk-taking is required to impress potential mates. Research also indicates that baseline sensation seeking may affect risk-taking behavior throughout the lifespan.
A priority in sexual attraction and dating can prove helpful in order to complete what reproductive advantage?
Answer: impress potential mates

Question: In 1671, Robert Boyle discovered and described the reaction between iron filings and dilute acids, which results in the production of hydrogen gas. In 1766, Henry Cavendish was the first to recognize hydrogen gas as a discrete substance, by naming the gas from a metal-acid reaction "flammable air". He speculated that "flammable air" was in fact identical to the hypothetical substance called "phlogiston" and further finding in 1781 that the gas produces water when burned. He is usually given credit for its discovery as an element. In 1783, Antoine Lavoisier gave the element the name hydrogen (from the Greek - hydro meaning "water" and - genes meaning "creator") when he and Laplace reproduced Cavendish's finding that water is produced when hydrogen is burned.
Is there an answer to this question: What does gas produce when burned?

Answer: water

An exception to the usual European qualification system happened in 2005, after Liverpool won the Champions League the year before, but did not finish in a Champions League qualification place in the Premier League that season. UEFA gave special dispensation for Liverpool to enter the Champions League, giving England five qualifiers. UEFA subsequently ruled that the defending champions qualify for the competition the following year regardless of their domestic league placing. However, for those leagues with four entrants in the Champions League, this meant that if the Champions League winner finished outside the top four in its domestic league, it would qualify at the expense of the fourth-placed team in the league. No association can have more than four entrants in the Champions League. This occurred in 2012, when Chelsea who had won the Champions League the previous year, but finished sixth in the league qualified for the Champions League in place of Tottenham Hotspur, who went into the Europa League.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many winning teams from an association can participate in the Champions League?
Ah, so..
No association can have more than four entrants in the Champions League
