question:
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:
Question: When was Giulio Cesare in Egitto composed? Passage:Radner pursued German studies for one semester, but left because she disliked it. She started training in an import–export business and had the best grades at the vocational school, but felt that it did not suit her. She applied to the Robert Schumann Hochschule for music in Düsseldorf and was one of seven selected from 200 applicants. Her voice teacher, Michaela Krämer, considered her to be a mezzo-soprano. Radner's father obtained additional voice lessons for her with Jeannette Zarou in Düsseldorf, and later with mezzo-soprano Marga Schiml, both of whom are experts in early music and Lieder. They recognized that she was really a contralto. Radner's mother died in 2003 after a long illness. Almost a year later, Radner earned her diploma. In the 2006 Bundeswettbewerb Gesang Berlin, she won the €3,000 third prize in the concert category and a scholarship from the Richard Wagner Society in Bayreuth to attend the 2007 Bayreuth Festival. In the concert division of the 2007 Cantilena Singing Competition, she placed second out of 120 vocalists from 19 countries. In 2008 she played Cornelia in Handel's Giulio Cesare in Egitto at the Theater Hagen. It was to be her only engagement as an ensemble member at a theatre. She decided that it was "not her world", not because it was no fun, but because she wanted to earn more, and she went independent. Radner was still a student in 2008 when she made her first public appearance under Zubin Mehta at the Palau de les Arts Reina Sofia in Valencia, singing Martin y Soler's oratorio Philitaei a Jonatha disperse. She gave a recital in June 2008.
