Input: Consider Input: Question: How long did the Egyptian revolution of 2011 take place? Passage:Following the Egyptian revolution of 2011 as part of the regional Arab Spring protests, Mubarak was ousted and the following year Mohamed Morsi who is backed by the Muslim Brotherhood won Egypt's first democractic elections. In 2013 Morsi was removed from power in a coup led by Abdel Fattah el-Sisi. Sisi has called for religious tolerance and has cracked down and banned the Muslim Brotherhood. He has closed thousands of mosques and has banned 'burkinis' on some beaches. A The Economist report in 2017 stated that Egyptians were turning more secular again, with supporters of sharia law dropping by more than half since 2011, people praying less than before, and gender equality now being widely accepted. The government has also acted to preserve its Jewish heritage through the restoration of the abandoned Eliyahu Hanavi Synagogue in Alexandria in 2017.

Input: Consider Input: Question: Which of the two congregations which provided leadership to the Pilgrims was founded first? Passage:The Pilgrims or Pilgrim Fathers were English settlers who established Plymouth Colony in Plymouth, Massachusetts. Their leadership came from the religious congregations of Brownists, or Separatist Puritans, who had fled religious persecution in England for the tolerance of 17th-century Holland in the Netherlands. They held Puritan Calvinist religious beliefs but, unlike most other Puritans, they maintained that their congregations should separate from the English state church. They eventually determined to establish a new settlement in the New World and arranged with investors to fund them. They established Plymouth Colony in 1620, which became the second successful English settlement in America, following the founding of Jamestown, Virginia in 1607. The Pilgrims' story became a central theme in the history and culture of the United States.

Input: Consider Input: Question: In what country were the earthquakes that caused the postponement of the race in which Oliver Turvey had a Super GT commitment? Passage:There was one driver change heading into the race. Having been in one of the Aguri cars since the first round of the season in Beijing, António Félix da Costa missed the ePrix because of a Deutsche Tourenwagen Masters commitment at the Red Bull Ring and was replaced by endurance racing driver René Rast. The deal was confirmed in the week before the race and was originally slated to be World Endurance Championship driver Adam Carroll but the agreement fell apart. It marked Rast's first participation in single-seater machinery since the Formula BMW ADAC in 2004 and practised on the team's simulator to familiarise himself with the car. Oliver Turvey was set to be replaced by the Formula Renault 3.5 driver Ben Hanley because of a Super GT commitment at the Autopolis circuit, but that race was postponed because of the Kumamoto earthquakes, and his Formula E seat was reinstated.
