Question: Question: Which country's air force was garrisoned at Taichung until 1955? Passage:Taichung International Airport was constructed during the era of Japanese rule and was named . The United States Air Force (USAF) had been garrisoning the base with two fighter squadrons until the Sino-American Mutual Defense Treaty came into force on March 3, 1955. The airport then expanded in 1954 according to the Sino-American Mutual Defense Treaty, and later renamed Ching Chuan Kang Air Base (CCK) in memory of General Qiu Qingquan. In 1966 the American Air Force established a joint forces air-base at CCK. It was the largest air force base in the Far East at the time, allowing Boeing B-52 Stratofortress bombers to land. During the Vietnam War, CCK became a depot for the USAF. The US Military used CCK and Shuinan Airport to run many of its long-distance Vietnam, Cambodia and Laotian bombing, scouting and cargo transport runs during the Vietnam War era. This base was shut down and most American facilities were removed after U.S. established diplomatic relations with the China in 1979.

Question: Question: What age was Pastornicky's replacement in 2012? Passage:Following the conclusion of the 2011 season, Braves general manager Frank Wren highlighted several important areas to improve during the offseason. Since most players were committed contractually to the team in 2012, Wren acknowledged that he would likely make few major changes. One spot that was mentioned for a major overhaul was the shortstop position, where Alex González had played since the Yunel Escobar trade with Toronto in July 2010. González entered the offseason as a free agent and proved too expensive for the team. Wren ultimately allowed prospect Tyler Pastornicky the starting duties in 2012, until he was replaced by Andrelton Simmons in mid-June. When Simmons was hurt in July, Jack Wilson, Paul Janish, and Martín Prado filled in for him. While center fielder Michael Bourn returned to his position in 2012, Wren also suggested that the corner outfield positions were areas of contention. In 2011, the Atlanta outfielders finished the season last in the National League in on-base plus slugging and slugging percentage. Wren stated that right fielder Jason Heyward and left fielder Martín Prado had no guarantee of getting the starting jobs in 2012. On the day after the Braves were eliminated from the playoffs in 2011, Wren said that veteran starter Derek Lowe was unlikely to have a spot in the starting rotation in 2012, due his poor performance in 2011 and a plethora of rookie pitching talent in the Braves farm system. With Lowe guaranteed $15 million in 2012, Wren projected that any of Lowe's salary picked up by another team would significantly assist his efforts to find a shortstop or outfielder. By the end of October, Lowe was traded to the Indians.

Question: Question: In what issues of Batman did the villain Black Mask originally show up? Passage:Within the regular series, the buildup to "Knightfall" begins with a six-issue run in Batman #484-489 (September 1992 - February 1993), in which Batman (at the onset of a personal psychological mid-life crisis) is forced to deal, in rapid succession, with the returning villain Black Mask and his gang (who target Bruce Wayne and Lucius Fox), a crazed killer called Metalhead, and a sharpshooter assassin hired by an imprisoned mobster to murder Commissioner Gordon. Batman begins to feel that he has lost his edge, especially after his failure to capture Black Mask. He finds himself unable to meditate or even focus. As Bruce Wayne, he contacts holistic therapist Shondra Kinsolving for treatment. He also assigns Robin (Tim Drake) to train Jean-Paul Valley in detective work to aid them as an ally, hoping to guide Valley's brainwashing away from making him a villainous threat. Despite the advice of everyone in his life, including Dr. Kinsolving, Bruce refuses to rest and continues to pursue his self-imposed duty despite his worsening condition (although not explicitly noted as a cause, these events take place immediately after the death of Superman, Batman's peer, elsewhere in the DC Universe).
