The discovery of the element is credited to the German chemist Martin Heinrich Klaproth. While he was working in his experimental laboratory in Berlin in 1789, Klaproth was able to precipitate a yellow compound (likely sodium diuranate) by dissolving pitchblende in nitric acid and neutralizing the solution with sodium hydroxide. Klaproth assumed the yellow substance was the oxide of a yet-undiscovered element and heated it with charcoal to obtain a black powder, which he thought was the newly discovered metal itself (in fact, that powder was an oxide of uranium). He named the newly discovered element after the planet Uranus, (named after the primordial Greek god of the sky), which had been discovered eight years earlier by William Herschel.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year didn't the discovery of uranium occur?
Ah, so.. unanswerable

Barcelona is one of three founding members of the Primera División that have never been relegated from the top division, along with Athletic Bilbao and Real Madrid. In 2009, Barcelona became the first Spanish club to win the continental treble consisting of La Liga, Copa del Rey, and the UEFA Champions League, and also became the first football club to win six out of six competitions in a single year, completing the sextuple in also winning the Spanish Super Cup, UEFA Super Cup and FIFA Club World Cup. In 2011, the club became European champions again and won five trophies. This Barcelona team, which reached a record six consecutive Champions League semi-finals and won 14 trophies in just four years under Pep Guardiola, is considered by some in the sport to be the greatest team of all time. In June 2015, Barcelona became the first European club in history to achieve the continental treble twice.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many competition wins did Barcelona have in 2011?
Ah, so..
