[Q]: Question: Was the people's Liberation Army still in operation during the civil war in 1949? Passage:In ancient times the area around Changzhi (Including Jincheng) was known as Shangdang. Changzhi was the site of the Shangdang Campaign, the first battle between the Kuomintang and the People's Liberation Army after the end of World War II. The campaign began in August 1945 and lasted until October. It began when the local Shanxi warlord, Yan Xishan, attempted to retake the region from Communist forces. Yan's forces were eventually defeated by an army led by Liu Bocheng, who was later named one of China's Ten Great Marshals. Liu's political commissar was Deng Xiaoping, who later became China's "paramount leader". The campaign ended with the complete destruction of Yan's army, most of which joined the Communists after surrendering. Following the Shangdang Campaign, the Communists remained in control of the region until they won the civil war in 1949.

[Q]: Question: What year was the treaty that opened up the Korean Peninsula to Japanese trade signed? Passage:Un'yō  was one of the ships dispatched to Kyūshū in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yō in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yō  was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yō  was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.

[Q]: Question: Which of the buildings that had their windows blown out is older? Passage:The Ritz Carlton, Westin Peachtree Plaza, Georgia-Pacific Building, SunTrust Plaza (where more than 60 people had to be relocated out of their offices), Equitable Building, and Georgia State University also had windows blown out (300 at Equitable alone), as did The Tabernacle (a former church with stained glass that is now a concert venue). The windows of the Westin continued to fall for days after the tornado, forcing police to keep several city blocks and MARTA's Peachtree Center station closed to pedestrians. The Georgia World Congress Center also sustained flooding while hosting a JROTC event and the Hinman Dental Meeting; Fox Sports Net took footage of a staircase in the new section of the complex that looked like a fountain with water cascading down it. The annual Atlanta Home Show and all other events were cancelled for the weekend in the GWCC complex, as was the Atlanta St. Patrick's Day Parade scheduled for the next day. WRAS FM at Georgia State University was off the air for two days, though it was not stated whether its studio or tower sustained damage, or if this was due to security or safety concerns, or power outages. The historic Rialto Theatre at GSU also sustained roof damage, which caused water damage inside.
