Question: During which centuries were the Kyoto Imperial Palace and the Sento Imperial Palace home to the Emperors of Japan? Passage:With its 2,000 religious places – 1,600 Buddhist temples and 400 Shinto shrines, as well as palaces, gardens and architecture intact – it is one of the best preserved cities in Japan. Among the most famous temples in Japan are Kiyomizu-dera, a magnificent wooden temple supported by pillars off the slope of a mountain; Kinkaku-ji, the Temple of the Golden Pavilion; Ginkaku-ji, the Temple of the Silver Pavilion; and Ryōan-ji, famous for its rock garden. The Heian Jingū is a Shinto shrine, built in 1895, celebrating the Imperial family and commemorating the first and last emperors to reside in Kyoto. Three special sites have connections to the imperial family: the Kyoto Gyoen area including the Kyoto Imperial Palace and Sentō Imperial Palace, homes of the Emperors of Japan for many centuries; Katsura Imperial Villa, one of the nation's finest architectural treasures; and Shugaku-in Imperial Villa, one of its best Japanese gardens. In addition, the temple of Sennyu-ji houses the tombs of the emperors from Shijō to Kōmei.

Question: In what city did Harry Newman go to college? Passage:The 1935 NFL Championship Game was held on December 15, 1935, at University of Detroit Stadium (some sources call it Titan Stadium) in Detroit. The game was played in a snowstorm in front of 12,000 spectators. It was the 3rd annual title game for the NFL. The champion of the Western Division was the Detroit Lions (7–3–2) and the champion of the Eastern Division was the New York Giants (9–3). On the opening drive of the game, the Lions Glenn Presnell threw a 36-yard pass to Frank Christensen, and Ace Gutowsky threw another long pass to Ed Klewicki at the Giants' 8-yard line. Gutowsky then ran the ball into the end zone to give the Lions a 7–0 lead. The Lions scored again after Christensen intercepted a pass thrown by New York's Ed Danowski and ran it back to midfield. Three plays later, Dutch Clark ran 40 yards for a touchdown. In the fourth quarter, the Lions blocked a punt, and George Christensen recovered the ball on the Giants' 22-yard line. Ernie Caddel ran the ball in from the one-yard line for the Lions' third touchdown. The Lions added to their lead late in the game after Parker intercepted a pass from New York quarterback (and former University of Michigan star) Harry Newman on the Giants' 45-yard line and returned it to the nine-yard line. Buddy Parker ran for the touchdown as the Lions won the championship by a final score of 26–7.
