Problem: Maintaining continuity with his predecessors, John XXIII continued the gradual reform of the Roman liturgy, and published changes that resulted in the 1962 Roman Missal, the last typical edition containing the Tridentine Mass established in 1570 by Pope Pius V at the request of the Council of Trent and whose continued use Pope Benedict XVI authorized in 2007, under the conditions indicated in his motu proprio Summorum Pontificum. In response to the directives of the Second Vatican Council, later editions of the Roman Missal present the 1970 form of the Roman Rite.
What did the changes published by Pope Benedict XVI cause?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The sweet wort collected from sparging is put into a kettle, or "copper" (so called because these vessels were traditionally made from copper), and boiled, usually for about one hour. During boiling, water in the wort evaporates, but the sugars and other components of the wort remain; this allows more efficient use of the starch sources in the beer. Boiling also destroys any remaining enzymes left over from the mashing stage. Hops are added during boiling as a source of bitterness, flavour and aroma. Hops may be added at more than one point during the boil. The longer the hops are boiled, the more bitterness they contribute, but the less hop flavour and aroma remains in the beer.
During what process is the remaining sugar destroyed?
A: unanswerable


Context and question: The final is normally held the Saturday after the Premier League season finishes in May. The only seasons in recent times when this pattern was not followed were 1999–2000, when most rounds were played a few weeks earlier than normal as an experiment, and 2010–11 and 2012–13 when the FA Cup Final was played before the Premier League season had finished, to allow Wembley Stadium to be ready for the UEFA Champions League final, as well as in 2011–12 to allow England time to prepare for that summer's European Championships.
When does the final never take place?
Answer: unanswerable


Question: The Palacio Taranco is located in front of the Plaza Zabala, in the heart of Ciudad Vieja. It was erected in the early 20th century as the residence of the Ortiz Taranco brothers on the ruins of Montevideo's first theatre (of 1793), during a period in which the architectural style was influenced by French architecture. The palace was designed by French architects Charles Louis Girault and Jules Chifflot León who also designed the Petit Palais and the Arc de Triomphe in Paris. It passed to the city from the heirs of the Tarancos in 1943, along with its precious collection of Uruguayan furniture and draperies and was deemed by the city as an ideal place for a museum; in 1972 it became the Museum of Decorative Arts of Montevideo and in 1975 it became a National Heritage Site. The Decorative Arts Museum has an important collection of European paintings and decorative arts, ancient Greek and Roman art and Islamic ceramics of the 10th–18th century from the area of present-day Iran. The palace is often used as a meeting place by the Uruguayan government.
Is there an answer to this question: The Palacio Taranco was erected to be the residence for whom?

Answer: Ortiz Taranco brothers


Problem: John, King of England:

After Richard's death on 6 April 1199 there were two potential claimants to the Angevin throne: John, whose claim rested on being the sole surviving son of Henry II, and young Arthur I of Brittany, who held a claim as the son of John's elder brother Geoffrey. Richard appears to have started to recognise John as his heir presumptive in the final years before his death, but the matter was not clear-cut and medieval law gave little guidance as to how the competing claims should be decided. With Norman law favouring John as the only surviving son of Henry II and Angevin law favouring Arthur as the only son of Henry's elder son, the matter rapidly became an open conflict. John was supported by the bulk of the English and Norman nobility and was crowned at Westminster, backed by his mother, Eleanor. Arthur was supported by the majority of the Breton, Maine and Anjou nobles and received the support of Philip II, who remained committed to breaking up the Angevin territories on the continent. With Arthur's army pressing up the Loire valley towards Angers and Philip's forces moving down the valley towards Tours, John's continental empire was in danger of being cut in two.

When did Richard die?

6 April 1199
