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: Which of the players that Gray was traded to the Indians for had a longer career with the Rangers? Passage:Before the 1980 season began, the Rangers traded Gray, Mike Bucci, and Larry McCall to the Cleveland Indians for David Clyde and Jim Norris. That year, he hit .148 in 28 games with Cleveland, and spent most of the year with the Tacoma Tigers. The following offseason, he was picked up by the Seattle Mariners in the Rule 5 Draft, as manager Rene Lachemann watched Gray play in the Pacific Coast League and wanted him in the starting lineup. He had his best season in 1981, splitting time at first base with starter Bruce Bochte and hitting 13 home runs in just 208 at bats. The next season, he hit .257 in a career high 80 games. After the season, his contract was sold to the California Angels. He played from 1983 to 1987 in the Mexican League, primarily with the Rieleros de Aguascalientes, before retiring from baseball.
