Question: Is the CEO of Radioshack a female? Passage:Many store closings ensued at the mall in the early 1990s, including five chain clothing stores and a T.J. Cinnamons bakery all in late 1991 and early 1992. Despite these closures, the mall also gained Champs Sports and a dollar store, and its occupancy level of 92 percent was higher than the average occupancy rate of 85 percent for malls in the Midwestern United States at the time. Limited Brands (now L Brands) opened three stores then under its ownership in 1993: a combination Limited Express/Structure store (now known as Express and Express Men, respectively) and Victoria's Secret. The combined Limited Express/Structure took the place of Herman's World of Sporting Goods, which had closed earlier in the year. According to the mall's then-general manager, Limited Brands had wanted to open all three brands at the mall for several years, and that all three were highly demanded by shoppers due to their presence at Meridian Mall. Following these additions, Lansing and Meridian malls had nearly 60 stores in common with each other and nearly 40 others that were unique to each. In 1995, the mall received new planters and an enlarged customer service booth. Meanwhile, RadioShack and Regis Hairstylists moved to new storefronts, Lane Bryant expanded its existing store, and Buckle, Bombay Company, and Pacific Sunwear joined. These were followed in 1996 by Gymboree, Bath & Body Works, and the second Disney Store in the state of Michigan.

Question: Did Dong Cheng have any children when he was executed? Passage:Liu Bei and his oath brothers Guan Yu and Zhang Fei swore allegiance to the Han Empire in the Oath of the Peach Garden and pledged to do their best for the people. However, their ambitions were not realised as they did not receive due recognition for helping to suppress the Yellow Turban Rebellion and participating in the campaign against Dong Zhuo. After Liu Bei succeeded Tao Qian as the governor of Xu Province, he offered shelter to Lü Bu, who had just been defeated by Cao Cao. However, Lü Bu betrayed his host, seized control of the province and attacked Liu Bei. Liu Bei combined forces with Cao Cao and defeated Lü Bu at the Battle of Xiapi. Liu Bei then followed Cao Cao back to the imperial capital, Xu, where Emperor Xian honoured him as his "Imperial Uncle". When Cao Cao showed signs that he wanted to usurp the throne, Emperor Xian wrote a secret decree in blood to his father-in-law, Dong Cheng, and ordered him to get rid of Cao. Dong Cheng secretly contacted Liu Bei and others and they planned to assassinate Cao Cao. However, the plot was leaked out and Cao Cao had Dong Cheng and the others arrested and executed along with their families.
