Problem: John, King of England:

When the Archbishop of Canterbury, Hubert Walter, died on 13 July 1205, John became involved in a dispute with Pope Innocent III that would lead to the king's excommunication. The Norman and Angevin kings had traditionally exercised a great deal of power over the church within their territories. From the 1040s onwards, however, successive popes had put forward a reforming message that emphasised the importance of the church being "governed more coherently and more hierarchically from the centre" and established "its own sphere of authority and jurisdiction, separate from and independent of that of the lay ruler", in the words of historian Richard Huscroft. After the 1140s, these principles had been largely accepted within the English church, albeit with an element of concern about centralising authority in Rome. These changes brought the customary rights of lay rulers such as John over ecclesiastical appointments into question. Pope Innocent was, according to historian Ralph Turner, an "ambitious and aggressive" religious leader, insistent on his rights and responsibilities within the church.

Who said Pope Innocent was an ambitious and aggressive religious leader?

A: historian Ralph Turner

Problem: The former ten-year moratorium on the construction of new nuclear power plants was the result of a citizens' initiative voted on in 1990 which had passed with 54.5% Yes vs. 45.5% No votes. Plans for a new nuclear plant in the Canton of Bern have been put on hold after the accident at the Fukushima Daiichi power plant in 2011. The Swiss Federal Office of Energy (SFOE) is the office responsible for all questions relating to energy supply and energy use within the Federal Department of Environment, Transport, Energy and Communications (DETEC). The agency is supporting the 2000-watt society initiative to cut the nation's energy use by more than half by the year 2050.
What is the 2000-watt society initiative designed to cut by more than half by 2050?

Answer: the nation's energy use

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The polyphony of Christian a cappella music began to develop in Europe around the late 15th century, with compositions by Josquin des Prez. The early a cappella polyphonies may have had an accompanying instrument, although this instrument would merely double the singers' parts and was not independent. By the 16th century, a cappella polyphony had further developed, but gradually, the cantata began to take the place of a cappella forms. 16th century a cappella polyphony, nonetheless, continued to influence church composers throughout this period and to the present day. Recent evidence has shown that some of the early pieces by Palestrina, such as what was written for the Sistine Chapel was intended to be accompanied by an organ "doubling" some or all of the voices. Such is seen in the life of Palestrina becoming a major influence on Bach, most notably in the aforementioned Mass in B Minor. Other composers that utilized the a cappella style, if only for the occasional piece, were Claudio Monteverdi and his masterpiece, Lagrime d'amante al sepolcro dell'amata (A lover's tears at his beloved's grave), which was composed in 1610, and Andrea Gabrieli when upon his death it was discovered many choral pieces, one of which was in the unaccompanied style. Learning from the preceding two composeres, Heinrich Schutz utilized the a cappella style in numerous pieces, chief among these were the pieces in the oratorio style, which were traditionally performed during the Easter week and dealt with the religious subject matter of that week, such as Christ's suffering and the Passion. Five of Schutz's Historien were Easter pieces, and of these the latter three, which dealt with the passion from three different viewpoints, those of Matthew, Luke and John, were all done a cappella style. This was a near requirement for this type of piece, and the parts of the crowd were sung while the solo parts which were the quoted parts from either Christ or the authors were performed in a plainchant.
What did the a cappella form take the place of during the 16th century?
A: unanswerable

Context and question: U.S. President Barack Obama has rarely used the term, but in his inaugural address on 20 January 2009, he stated "Our nation is at war, against a far-reaching network of violence and hatred." In March 2009 the Defense Department officially changed the name of operations from "Global War on Terror" to "Overseas Contingency Operation" (OCO). In March 2009, the Obama administration requested that Pentagon staff members avoid use of the term, instead using "Overseas Contingency Operation". Basic objectives of the Bush administration "war on terror", such as targeting al Qaeda and building international counterterrorism alliances, remain in place. In December 2012, Jeh Johnson, the General Counsel of the Department of Defense, stated that the military fight will be replaced by a law enforcement operation when speaking at Oxford University, predicting that al Qaeda will be so weakened to be ineffective, and has been "effectively destroyed", and thus the conflict will not be an armed conflict under international law. In May 2013, Obama stated that the goal is "to dismantle specific networks of violent extremists that threaten America"; which coincided with the U.S. Office of Management and Budget having changed the wording from "Overseas Contingency Operations" to "Countering Violent Extremism" in 2010.
What term did Obama want the government to stop using?
Answer: war on terror

Question: Carnaval de Solsona takes place in Solsona, Lleida. It is one of the longest; free events in the streets, and nightly concerts run for more than a week. The Carnival is known for a legend that explains how a donkey was hung at the tower bell because the animal wanted to eat grass that grew on the top of the tower. To celebrate this legend, locals hang a stuffed donkey at the tower that "pisses" above the excited crowd using a water pump. This event is the most important and takes place on Saturday night. For this reason, the inhabitants are called "matarrucs" ("donkey killers").
Is there an answer to this question: What was a donkey hung from according to local legend?

Answer: the tower bell
