Question: Finite symmetry groups such as the Mathieu groups are used in coding theory, which is in turn applied in error correction of transmitted data, and in CD players. Another application is differential Galois theory, which characterizes functions having antiderivatives of a prescribed form, giving group-theoretic criteria for when solutions of certain differential equations are well-behaved.u["] Geometric properties that remain stable under group actions are investigated in (geometric) invariant theory.
Is there an answer to this question: Which form of finite symmetry groups are useless in coding theory?

Answer: unanswerable

Question: Christianity is the predominant religion of Switzerland (about 71% of resident population and 75% of Swiss citizens), divided between the Catholic Church (38.21% of the population), the Swiss Reformed Church (26.93%), further Protestant churches (2.89%) and other Christian denominations (2.79%). There has been a recent rise in Evangelicalism. Immigration has brought Islam (4.95%) and Eastern Orthodoxy (around 2%) as sizeable minority religions. According to a 2015 poll by Gallup International, 12% of Swiss people self-identified as "convinced atheists."
Is there an answer to this question: What religion has immigration brought by 4.95%?

Question: Paul VI supported the new-found harmony and cooperation with Protestants on so many levels. When Cardinal Augustin Bea went to see him for permission for a joint Catholic-Protestant translation of the Bible with Protestant Bible societies, the pope walked towards him and exclaimed, "as far as the cooperation with Bible societies is concerned, I am totally in favour." He issued a formal approval on Pentecost 1967, the feast on which the Holy Spirit descended on the Christians, overcoming all linguistic difficulties, according to Christian tradition.
Is there an answer to this question: In what year did Paul VI officially declare his support of a cross faith translation of the bible?

Answer: 1967

Question: Libya's economy witnessed increasing privatization; although rejecting the socialist policies of nationalized industry advocated in The Green Book, government figures asserted that they were forging "people's socialism" rather than capitalism. Gaddafi welcomed these reforms, calling for wide-scale privatization in a March 2003 speech. In 2003, the oil industry was largely sold to private corporations, and by 2004, there was $40 billion of direct foreign investment in Libya, a sixfold rise over 2003. Sectors of Libya's population reacted against these reforms with public demonstrations, and in March 2006, revolutionary hard-liners took control of the GPC cabinet; although scaling back the pace of the changes, they did not halt them. In 2010, plans were announced that would have seen half the Libyan economy privatized over the following decade. While there was no accompanying political liberalization, with Gaddafi retaining predominant control, in March 2010, the government devolved further powers to the municipal councils. Rising numbers of reformist technocrats attained positions in the country's governance; best known was Gaddafi's son and heir apparent Saif al-Islam Gaddafi, who was openly critical of Libya's human rights record. He led a group who proposed the drafting of the new constitution, although it was never adopted, and in October 2009 was appointed to head the PSLC. Involved in encouraging tourism, Saif founded several privately run media channels in 2008, but after criticising the government they were nationalised in 2009. In October 2010, Gaddafi apologized to African leaders on behalf of Arab nations for their involvement in the African slave trade.
Is there an answer to this question: In what month and year did Gaddafi make a speech promoting economic privatization?

Answer:
March 2003
