Input: Consider Input: Question: How many times did the Wisconsin Progressive Party win the governor of Wisconsin? Passage:Wiley was the Republican candidate for governor of Wisconsin in 1936, but his bid failed. Philip La Follette and the new Wisconsin Progressive Party, which split from the Republicans in 1934, won the election. In 1938, Wiley was elected to the U.S. Senate by defeating incumbent F. Ryan Duffy. In 1944, he was challenged by United States Marine Corps Captain Joseph R. McCarthy in the Republican primary. He defeated McCarthy and won the general election. Wiley, then an isolationist in foreign policy, and Governor Walter S. Goodland supported Republican presidential nominee Thomas E. Dewey in the 1944 race over incumbent Franklin D. Roosevelt, and Dewey won Wisconsin's electoral votes but fell far short nationally.

Input: Consider Input: Question: On what album was the Gerry Rafferty song from that is referenced in the show? Passage:While telling Bart and Lisa about 1990, Homer says, "Tracey Ullman was entertaining America with [...] crudely drawn filler material." This is a reference to The Simpsonss debut as "bumpers" airing before and after commercials on The Tracey Ullman Show. The song "Those Were the Days" parodies the opening credits of the television show All in the Family. One of the people who run over the saxophone is a man on a tricycle, who promptly falls over. This is a reference to the show Rowan & Martin's Laugh-In. At the beginning of the flashback, the song "Don't Worry, Be Happy" by Bobby McFerrin can be heard. In the flashback, Dr. Hibbert fashioned his hair and attire like Mr. T in The A-Team. Homer can be seen watching Twin Peaks and The Giant is then shown waltzing with the White Horse. In King Toot's music store, when Homer buys Lisa her first saxophone, there is a guitar in the background that is similar to Eddie Van Halen's "Frankenstrat" guitar. The photo beside Kent Brockman on the news has him modeled after the Coppertone Girl. At the end of the episode, Lisa performs a brief, cruder rendition of the hook of "Baker Street" by Gerry Rafferty on her new saxophone before the music segues into the original song.

Input: Consider Input: Question: What is the age difference between Byzantine Emperor and his father-in-law? Passage:With the ascendance of Simeon I to the throne in 893, the long-lasting peace with the Byzantine Empire established by his father was about to end. A conflict arose when Byzantine Emperor Leo VI the Wise, acting under pressure from his wife Zoe Zaoutzaina and her father, Stylianos Zaoutzes, moved the marketplace for Bulgarian goods from Constantinople to Thessaloniki, where Bulgarian merchants were heavily taxed. Forced to take action, in the autumn of 894 Simeon invaded the Byzantine Empire from the north, meeting little opposition due to the concentration of most Byzantine forces in eastern Anatolia to counter Arab invasions. Informed of the Bulgarian offensive, the surprised Leo sent an army consisting of guardsmen and other military units from the capital to halt Simeon, but his troops were routed somewhere in the theme of Macedonia.The Magyars managed to defeat Simeon's army twice, but in 896 they were routed in the Battle of Southern Buh. The war ended in 896 with a great Bulgarian victory near Bulgarophygon in Eastern Thrace. The market was returned to Constantinople, and the Byzantine Emperor had to pay annual tribute to Bulgaria. More importantly, with help from the Pechenegs Simeon successfully fended off a Magyar invasion, which was coordinated with the Byzantines.
