Problem: I know that the answer to the question "What format was more popular with the "hillbilly" market?" is in "Some of Elvis Presley's early singles on Sun Records might have sold more copies on 78 than on 45. This is because the majority of those sales in 195455 were to the "hillbilly" market in the South and Southwestern United States, where replacing the family 78 rpm player with a new 45 rpm player was a luxury few could afford at the time. By the end of 1957, RCA Victor announced that 78s accounted for less than 10% of Presley's singles sales, essentially announcing the death throes of the 78 rpm format. The last Presley single released on 78 in the United States was RCA Victor 20-7410, I Got Stung/One Night (1958), while the last 78 in the UK was RCA 1194, A Mess Of Blues/Girl Of My Best Friend (1960).". Can you tell me what it is?

A: 78

Problem: Given the question: I know that the answer to the question "What did Madonna do four months after adopting Mercy James?" is in "Life with My Sister Madonna, a book by Madonna's brother Christopher, debuted at number two on The New York Times bestseller list. The book caused some friction between Madonna and her brother, because of the unsolicited publication. Problems also arose between Madonna and Ritchie, with the media reporting that they were on the verge of separation. Ultimately, Madonna filed for divorce from Ritchie, citing irreconcilable differences, which was finalized in December 2008. She decided to adopt from Malawi. The country's High Court initially approved the adoption of Chifundo "Mercy" James; however, the application was rejected because Madonna was not a resident of the country. Madonna appealed, and on June 12, 2009, the Supreme Court of Malawi granted Madonna the right to adopt Mercy James. She also released Celebration, her third greatest-hits album and final release with Warner. It contained the new songs "Celebration" and "Revolver" along with 34 hits spanning her career. Celebration reached number one in the UK, tying her with Elvis Presley as the solo act with most number one albums in the British chart history. She appeared at the 2009 MTV Video Music Awards on September 13, 2009, to speak in tribute to deceased pop star Michael Jackson.". Can you tell me what it is?

input question: I know that the answer to the question "Vacuum fluctuations are the result of what?" is in "QED vacuum has interesting and complex properties. In QED vacuum, the electric and magnetic fields have zero average values, but their variances are not zero. As a result, QED vacuum contains vacuum fluctuations (virtual particles that hop into and out of existence), and a finite energy called vacuum energy. Vacuum fluctuations are an essential and ubiquitous part of quantum field theory. Some experimentally verified effects of vacuum fluctuations include spontaneous emission and the Lamb shift. Coulomb's law and the electric potential in vacuum near an electric charge are modified.". Can you tell me what it is????
output answer: electric and magnetic fields have zero average values, but their variances are not zero

I know that the answer to the question "When did the TRNC first become a sovereign nation?" is in "Since 1965, following clashes between the two communities, the Turkish Cypriot seats in the House remain vacant. In 1974 Cyprus was divided de facto when the Turkish army occupied the northern third of the island. The Turkish Cypriots subsequently declared independence in 1983 as the Turkish Republic of Northern Cyprus but were recognised only by Turkey. In 1985 the TRNC adopted a constitution and held its first elections. The United Nations recognises the sovereignty of the Republic of Cyprus over the entire island of Cyprus.".

Answer: 1983

Q: I know that the answer to the question "Is Spain a symmetric or asymmetric federalism?" is in "Where every component state of a federation possesses the same powers, we are said to find 'symmetric federalism'. Asymmetric federalism exists where states are granted different powers, or some possess greater autonomy than others do. This is often done in recognition of the existence of a distinct culture in a particular region or regions. In Spain, the Basques and Catalans, as well as the Galicians, spearheaded a historic movement to have their national specificity recognized, crystallizing in the "historical communities" such as Navarre, Galicia, Catalonia, and the Basque Country. They have more powers than the later expanded arrangement for other Spanish regions, or the Spain of the autonomous communities (called also the "coffee for everyone" arrangement), partly to deal with their separate identity and to appease peripheral nationalist leanings, partly out of respect to specific rights they had held earlier in history. However, strictly speaking Spain is not a federalism, but a decentralized administrative organization of the state.". Can you tell me what it is?
A: Spain is not a federalism, but a decentralized administrative organization of the state

[Q]: I know that the answer to the question "How do you know when when a treaty is done?" is in "The end of a treaty, the eschatocol (or closing protocol), is often signaled by a clause like "in witness whereof" or "in faith whereof," the parties have affixed their signatures, followed by the words "DONE at," then the site(s) of the treaty's execution and the date(s) of its execution. The date is typically written in its most formal, longest possible form. For example, the Charter of the United Nations was "DONE at the city of San Francisco the twenty-sixth day of June, one thousand nine hundred and forty-five." If the treaty is executed in multiple copies in different languages, that fact is always noted, and is followed by a stipulation that the versions in different languages are equally authentic.".
