Problem: The X-10 Graphite Reactor at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee, formerly known as the Clinton Pile and X-10 Pile, was the world's second artificial nuclear reactor (after Enrico Fermi's Chicago Pile) and was the first reactor designed and built for continuous operation. Argonne National Laboratory's Experimental Breeder Reactor I, located at the Atomic Energy Commission's National Reactor Testing Station near Arco, Idaho, became the first nuclear reactor to create electricity on 20 December 1951. Initially, four 150-watt light bulbs were lit by the reactor, but improvements eventually enabled it to power the whole facility (later, the town of Arco became the first in the world to have all its electricity come from nuclear power generated by BORAX-III, another reactor designed and operated by Argonne National Laboratory). The world's first commercial scale nuclear power station, Obninsk in the Soviet Union, began generation with its reactor AM-1 on 27 June 1954. Other early nuclear power plants were Calder Hall in England, which began generation on 17 October 1956, and the Shippingport Atomic Power Station in Pennsylvania, which began on 26 May 1958. Nuclear power was used for the first time for propulsion by a submarine, the USS Nautilus, in 1954.
On what date did Breeder Reactor I first make electricity?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The introduction of the guided missile resulted in a significant shift in anti-aircraft strategy. Although Germany had been desperate to introduce anti-aircraft missile systems, none became operational during World War II. Following several years of post-war development, however, these systems began to mature into viable weapons systems. The US started an upgrade of their defences using the Nike Ajax missile, and soon the larger anti-aircraft guns disappeared. The same thing occurred in the USSR after the introduction of their SA-2 Guideline systems.
Which weapon caused a major shift in anti-aircraft strategy?
A: guided missile

Context and question: In the 19th century, a house near Ephesus in Turkey was found, based on the visions of Anne Catherine Emmerich, an Augustinian nun in Germany. It has since been visited as the House of the Virgin Mary by Roman Catholic pilgrims who consider it the place where Mary lived until her assumption. The Gospel of John states that Mary went to live with the Disciple whom Jesus loved,[Jn 19:27] identified as John the Evangelist.[citation needed] Irenaeus and Eusebius of Caesarea wrote in their histories that John later went to Ephesus, which may provide the basis for the early belief that Mary also lived in Ephesus with John.
Where did Anne Catherine Emmerich live?
Answer: unanswerable

Question: Several notable video game developers criticized Microsoft for making its Windows Store a closed platform subject to its own regulations, as it conflicted with their view of the PC as an open platform. Markus "Notch" Persson (creator of the indie game Minecraft), Gabe Newell (co-founder of Valve Corporation and developer of software distribution platform Steam), and Rob Pardo from Activision Blizzard voiced concern about the closed nature of the Windows Store. However, Tom Warren of The Verge stated that Microsoft's addition of the Store was simply responding to the success of both Apple and Google in pursuing the "curated application store approach."
Is there an answer to this question: What was the main reasoning behind the creation of the Windows Store?

Answer: responding to the success of both Apple and Google in pursuing the "curated application store approach."

Question: A fervent follower of the absolutist cause, Elio had played an important role in the repression of the supporters of the Constitution of 1812. For this, he was arrested in 1820 and executed in 1822 by garroting. Conflict between absolutists and liberals continued, and in the period of conservative rule called the Ominous Decade (18231833), which followed the Trienio Liberal, there was ruthless repression by government forces and the Catholic Inquisition. The last victim of the Inquisition was Gaieta Ripoli, a teacher accused of being a deist and a Mason who was hanged in Valencia in 1824.
Is there an answer to this question: Who helped repress the supporters of the Constitution and was later executed for it?

Answer:
Elio
