Problem: Elizabeth II:

During the war, plans were drawn up to quell Welsh nationalism by affiliating Elizabeth more closely with Wales. Proposals, such as appointing her Constable of Caernarfon Castle or a patron of Urdd Gobaith Cymru (the Welsh League of Youth), were abandoned for various reasons, which included a fear of associating Elizabeth with conscientious objectors in the Urdd, at a time when Britain was at war. Welsh politicians suggested that she be made Princess of Wales on her 18th birthday. Home Secretary, Herbert Morrison supported the idea, but the King rejected it because he felt such a title belonged solely to the wife of a Prince of Wales and the Prince of Wales had always been the heir apparent. In 1946, she was inducted into the Welsh Gorsedd of Bards at the National Eisteddfod of Wales.

Who was the always the Prince of Wales?
---
A: heir apparent

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Burke was not merely presenting a peace agreement to Parliament; rather, he stepped forward with four reasons against using force, carefully reasoned. He laid out his objections in an orderly manner, focusing on one before moving to the next. His first concern was that the use of force would have to be temporary, and that the uprisings and objections to British governance in America would not be. Second, Burke worried about the uncertainty surrounding whether Britain would win a conflict in America. "An armament", Burke said, "is not a victory". Third, Burke brought up the issue of impairment; it would do the British Government no good to engage in a scorched earth war and have the object they desired (America) become damaged or even useless. The American colonists could always retreat into the mountains, but the land they left behind would most likely be unusable, whether by accident or design. The fourth and final reason to avoid the use of force was experience; the British had never attempted to rein in an unruly colony by force, and they did not know if it could be done, let alone accomplished thousands of miles away from home. Not only were all of these concerns reasonable, but some turned out to be prophetic – the American colonists did not surrender, even when things looked extremely bleak, and the British were ultimately unsuccessful in their attempts to win a war fought on American soil.
Who did Burke think Britain could beat at war?
A: unanswerable


Context and question: When John's elder brother Richard became king in September 1189, he had already declared his intention of joining the Third Crusade. Richard set about raising the huge sums of money required for this expedition through the sale of lands, titles and appointments, and attempted to ensure that he would not face a revolt while away from his empire. John was made Count of Mortain, was married to the wealthy Isabel of Gloucester, and was given valuable lands in Lancaster and the counties of Cornwall, Derby, Devon, Dorset, Nottingham and Somerset, all with the aim of buying his loyalty to Richard whilst the king was on crusade. Richard retained royal control of key castles in these counties, thereby preventing John from accumulating too much military and political power, and, for the time being, the king named the four-year-old Arthur of Brittany as the heir to the throne. In return, John promised not to visit England for the next three years, thereby in theory giving Richard adequate time to conduct a successful crusade and return from the Levant without fear of John seizing power. Richard left political authority in England – the post of justiciar – jointly in the hands of Bishop Hugh de Puiset and William Mandeville, and made William Longchamp, the Bishop of Ely, his chancellor. Mandeville immediately died, and Longchamp took over as joint justiciar with Puiset, which would prove to be a less than satisfactory partnership. Eleanor, the queen mother, convinced Richard to allow John into England in his absence.
When did Richard become king?
Answer: September 1189


Question: The black-body problem was revisited in 1905, when Rayleigh and Jeans (on the one hand) and Einstein (on the other hand) independently proved that classical electromagnetism could never account for the observed spectrum. These proofs are commonly known as the "ultraviolet catastrophe", a name coined by Paul Ehrenfest in 1911. They contributed greatly (along with Einstein's work on the photoelectric effect) to convincing physicists that Planck's postulate of quantized energy levels was more than a mere mathematical formalism. The very first Solvay Conference in 1911 was devoted to "the theory of radiation and quanta". Max Planck received the 1918 Nobel Prize in Physics "in recognition of the services he rendered to the advancement of Physics by his discovery of energy quanta".
Is there an answer to this question: In what year did Planck receive the Nobel Prize in Physics for his discovery of energy quanta?

Answer: 1918


QUES: The traditional energy supply of Thuringia is lignite, mined in the bordering Leipzig region. Since 2000, the importance of environmentally unfriendly lignite combustion has declined in favour of renewable energies, which reached an amount of 40% (in 2013), and more clean gas combustion, often carried out as Cogeneration in the municipal power stations. The most important forms of renewable energies are Wind power and Biomass, followed by Solar energy and Hydroelectricity. Furthermore, Thuringia hosts two big pumped storage stations: the Goldisthal Pumped Storage Station and the Hohenwarte Dam.

Where does Thuringia steal it's lignite?
