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.

Question: How old was Peder Paus during the Reformation? Passage:The Paus family (earlier spellings include Pauss and de Paus) () is a Norwegian family that first appeared as members of the elite of 16th-century Oslo. Two brothers from Oslo who both became priests, Hans (1587–1648) and Peder Povelsson Paus (1590–1653), have long been known as the family's earliest certain ancestors. In his book Slekten Paus ("The Paus family"), genealogist S.H. Finne-Grønn traced the family two further generations back, to Hans Olufsson (died 1570), a member of the royal clergy in Norway before and after the Reformation, who served as a canon at the royal chapel in Oslo, St Mary's Church, the seat of government of Norway at the time, and who belonged to the high nobility by virtue of his high ecclesiastical and governmental office. The name Paus is known in Oslo since the 14th century, notably as the name of the Lawspeaker of Oslo Nikolas Paus (mentioned 1329–1347) and as the name of one of medieval Oslo's "city farms" (mentioned 1324–1482) that was probably named after the lawspeaker or his family; while a relation between the older and the younger family of the name in Oslo is plausible, it has not been established. Regardless, the modern Paus family is likely the only surviving family to hail from the medieval city of Oslo which burned down in 1624 without being rebuilt, making it the family with the longest documented history in the Norwegian capital.

Question: Who signed the Treaty of Sevres? Passage:The intention declared in the royal speech at the opening of the Chamber of resuming the war against Kemal was supported by an official report issued on January 10 of a renewal of the Greek offensive to the northeast of Smyrna and in the Brussa area, and the same day the Greeks occupied Belejik. On the following day the Greek Liberal organ Patris published a letter from Nice, where Venizelos was residing at the time, confirming the Greek statesman's final decision to retire from politics. This decision was naturally not displeasing to the supporters of King Constantine, who a little later found another cause for jubilation when the king of Italy received the newly appointed Greek minister to Rome (January 13). Thus Italy was the first among foreign Allied and neutral powers to recognize King Constantine. But the enthusiasm was soon damped by the joint representations made on the 20th to the Greek government by the British and French ministers in Athens on the transformation of the Chamber into a National Assembly. This action by the two Allied governments was declared to be based on the rights of the powers in question as guarantors of the constitution of Greece, rights which they considered as still existent, since the Treaty of Sèvres, in which they were surrendered, had not yet been ratified by all the signatories. Early in February the Allied Supreme Council invited the Greek and Turkish governments to attend a conference to be held in the latter part of the month in London with the object of bringing about peace between the two countries. The invitation was coldly received in Athens, and was the cause of a split in the Dimitrios Rallis cabinet on the score of wounded personal vanities. Dimitrios Gounaris, minister of war, the real leader of the Constantino faction, who, in deference to Allied public opinion, which had stigmatized him as a pro-German, had after the defeat of the Venizelists been compelled to renounce his claims to the premiership in favor of the less compromised Rallis, after being also refused the presidency of the Greek delegation to the London conference, resigned, bringing about a ministerial crisis.
