Question: How large was Israel's GDP the year Dayan emigrated to that country? Passage:Yosef Dayan emigrated to Israel in 1968, and became a member of the right-wing Kach movement. Dayan is the founder of "Malchut Israel", a right-wing religious-political group in Israel advocating a return of the monarchy. In 2004, he became a member of the newly reconstituted Sanhedrin, a duplicate of the religious tribunal which convened during the time of the Second Temple, a group that had traditionally had seventy-one members. He has also achieved certain notoriety for his alleged central participation in so-called "death curse" ceremonies or Pulsa diNura aimed at Yitzhak Rabin and Ariel Sharon. These curses were presumably to request divine retribution after those former Prime Ministers advocated Israeli withdrawal from certain areas considered by some as inalienable parts of the promised land. Incidentally, Yitzhak Rabin was murdered soon after the first curse, and Ariel Sharon left in a persistent vegetative state after a brain haemorrhage following the second. He is also known to have supported Baruch Goldstein's (a fellow Meir Kahane disciple) terrorist actions in the Cave of the Patriarch's Massacre.

Question: How long had Darrell Royal been working as a head coach the year he learned about the wishbone offense? Passage:In 1968, Texas head coach Darrell Royal and his offensive coordinator Emory Bellard introduced what would become known as the wishbone offense. The wishbone was derived from the Split-T offense run at Oklahoma under Bud Wilkinson. In the formation, the quarterback lines up with a fullback and two tailbacks behind him, and on any play may keep the ball, hand off to the fullback, or pitch to a tailback. From the time Bryant arrived at Alabama through the 1970 season, the Crimson Tide ran a pro-style offense. By 1969, Bryant began to recruit larger linemen and tailbacks, and after a pair of six win seasons in 1969 and 1970, Bryant saw the success of the wishbone for the Longhorns and decided to implement the offense for the 1971 season. In spring 1971, Alabama assistants Mal Moore and Jimmy Sharpe traveled to Austin where they saw first hand how the wishbone operated during Texas' final week of spring practice.

Question: What country is Gunzenhausen in? Passage:Neuser was born in Gunzenhausen and was a popular pastor and theologian in Heidelberg in the 1560s, serving at the Peterskirche and later the Heiliggeistkirche. During the controversy over church discipline that developed in the late 1560s, Neuser became a leading member of the Antidisciplinist, and thus anti-Calvinist, faction led by Thomas Erastus. His disaffection with the ecclesiastical regime perhaps played some role in his doubts concerning orthodox Christian dogma. He wrote letters sternly attacking the doctrine of the trinity. He wrote to the Ottoman Sultan assuring Sultan that he would receive support in Germany if his conquests push him that far. Neuser along with another Antitrinitarian, Johann Sylvan, sought to dialog with the Turks. Neuser was accused of denying divinity to Jesus Christ and was consequently imprisoned. His associate, Johann Sylvan, was tortured and beheaded. Neuser confessed but managed to break out of prison. He later converted to Islam and traveled to Istanbul where he served the Ottoman Sultan.
Links: a. Ottoman Empire b. Johann Sylvan c. Gunzenhausen d. Calvinism
