Input: Consider Input: Question: How old was the Duke of Saxony when he appointed Adolf I to hold Holstein and Stormarn? Passage:He was appointed to hold as fiefs Holstein and Stormarn, including Hamburg, by Lothair, Duke of Saxony, in 1111. By this appointment Adolf became the leader of the defence of Germany against the Wagri. Allied with Henry, the prince of the Obotrites, he repeatedly waged war on Wagria and the Rugians. After Henry's death (1127), Adolf remained allied with his sons Canute and Sventepolk, but they were soon dead and Lothair, by then King of Germany, had made Canute Lavard, a Danish prince, Duke of Schleswig. Feeling his authority threatened by the Danish upstart, Adolf attacked his castle of Albergs, captured the garrison, and destroyed its defences. He left his counties intact to his second son, Adolf II, since his eldest, Hartung, had been killed in the Second Battle of Chlumec in 1126.

Input: Consider Input: Question: What country did Li Yuru have a successful 48-day run of 62 plays in? Passage:Graduating at age 17 in 1940, she established her own troupe with friends from the school. She organised a program of 62 new and traditional plays over a successful 48-day run in Shanghai, starring in 28 of them. Disliking the pressure she came under as an independent young actress, she disbanded the troupe and placed herself under the training and protection of older male actors: Xun Huisheng and Mei Lanfang, two of the "Four Great Dan"; Zhao Tongshan, the greatest "flowery" actor of the time; the "martial clown" Ye Shengzhang; the "educated clown" Ma Fulu; the "painted face" actor Jin Shaoshan; the "martial" actor Li Shaochun; the "Four Great Beards" Ma Lianliang, Tan Fuying, Yang Baosen, and Xi Xiaobo; and the other "old men" Zhou Xinfang and Tang Yunsheng. She also studied under the female impersonators Yu Lianquan and Cheng Yanqiu. The broad range of specialists expanded her repertoire greatly. During this period, Li gave successful performances of The Dragon and the Phoenix, The Courtyard of the Black Dragon, Two Phoenixes Flying Together, and Three Pretty Women. Her career and finances were largely handled by her mother, who was reckoned one of the "Four Famous Mothers" of the opera. She had her first daughter Li Li in 1944.
