[Q]: Question: When was Ōe Tokihiro's father born? Passage:The first castle on this site dates to the middle of the Kamakura period. Ōe Tokihiro, the younger son of Ōe no Hiromoto, a senior retainer of the Kamakura shogunate was granted lands in Dewa Province, and in 1238 changed his name to Nagai Tokihiro. The Nagai continued to rule for about 150 years. The Nagai were supplanted in the Sengoku period by the Date clan, and the famed warlord Date Masamune was born at Yonezawa Castle. After Date Masamune defeated the Ashina clan in 1589, he moved his main castle to Kurokawa Castle in Aizu and put Date Munekiyo in charge of Yonezawa. However, Toyotomi Hideyoshi did not agree, and forced Masamune move back to Yonezawa. In 1591, Masamune relocated to Iwadeyama Castle by orders of Hideyoshi, surrendering Yonezawa Castle to Gamō Ujisato. When Ujisato’s son, Gamō Hideyuki was moved to Utsunomiya in 1597, the castle was turned over to Uesugi Kagekatsu, as part of their vast 1,200,000 koku holdings based in Aizu. The castellan at this time was Naoe Kanetsugu.

[Q]: Question: Who was the first writer hired at Magill Magazine? Passage:He launched Magill magazine in September 1977 with Noel Pearson and Mary Holland. Magill became Ireland's foremost investigative publication. Among its writers were Gene Kerrigan, Pat Brennan and Paddy Agnew. He remained editor of Magill until 1983, when he became involved in the relaunch of the Sunday Tribune with Tony Ryan, then of GPA and later of Ryanair. A series of articles he published in Magill highlighting the links between the Workers' Party of Ireland and the Official IRA in the 1980s caused him and other journalists to receive death threats. After the publication of "The Lost Revolution: the Story of the Official IRA and the Workers' Party" it was revealed that the Official IRA had planned to assassinate him by planting a bomb on his boat, but the operation was called off at the last minute. He was editor of the Sunday Tribune until 1994. He has written a weekly column for The Irish Times since then, and since 2000, has written weekly for The Sunday Business Post. He started broadcasting on RTÉ radio in 1996.
