Question: What attributes did the goddess whose birthday was being observed commonly have associated with her? Passage:The Panathenaea (, "all-Athenian festival") was the most important festival for Athens and one of the grandest in the entire ancient Greek world. Except for slaves, all inhabitants of the polis could take part in the festival. This holiday of great antiquity is believed to have been the observance of Athena's birthday and honoured the goddess as the city's patron divinity, Athena Polias ('Athena of the city'). A procession assembled before dawn at the Dipylon gate in the northern sector of the city. The procession, led by the Kanephoros, made its way to the Areopagus and in front of the Temple of Athena Nike next to the Propylaea. Only Athenian citizens were allowed to pass through the Propylaea and enter the Acropolis. The procession passed the Parthenon and stopped at the great altar of Athena in front of the Erechtheum. Every four years a newly woven peplos was dedicated to Athena.
Links: a. Kanephoros b. Parthenon c. Peplos d. Athena

Question: How old was the Cardinals right fielder when he retired? Passage:The new season brought a Cardinals team that was much changed from the one that went 100-62 in 2005 but fell to the Houston Astros in the NLCS. Starting pitcher Matt Morris, second baseman Mark Grudzielanek, left fielder Reggie Sanders, and relief pitcher Julian Tavarez left the team via free agency. Relief pitcher Ray King was traded to Colorado. Right fielder Larry Walker retired. Brought in to replace the departed Cardinals were right fielder Juan Encarnacion, starting pitcher Sidney Ponson, relief pitchers Braden Looper and Ricardo Rincon, all via free agency, and second baseman Aaron Miles, acquired in the Ray King trade. Left field was left unsettled in the offseason and would remain so all year, with no player getting more than one-third of the playing time at that position.

Question: How many votes did Al Gore get the first time he ran for president? Passage:This article lists those who were potential candidates for the Democratic nomination for Vice President of the United States in the 1992 election. Arkansas Governor Bill Clinton won the 1992 Democratic nomination for President of the United States, and chose Tennessee Senator Albert Gore, Jr. as his running mate on July 9, 1992. Clinton considered roughly forty different candidates for vice president, including those who did not hold elective office, but Clinton ultimately chose Gore, a two-term Senator who had previously run for president in 1988. Former Assistant Secretary of State Warren Christopher led Clinton's vice presidential selection team. In making the selection, Clinton emphasized Gore's experience with foreign policy and environmental issues. Clinton's choice of a fellow young southern centrist defied conventional wisdom, but the choice of Gore was well-received, and Gore made an effective surrogate on the campaign trail. The Clinton-Gore ticket ultimately defeated the Republican Bush-Quayle ticket and the independent Perot-Stockdale ticket, and the Clinton-Gore duo became the youngest ticket in history to win a presidential election.
Links: a. Al Gore 1988 presidential campaign b. Democratic Party (United States) c. 1992 United States presidential election d. James Stockdale
