Input: Consider Input: 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.

Input: Consider Input: Question: Of the two colonies captured by Philip, which one was established first? Passage:Athens and Macedon had been at war since 356 BC, after Philip's capture of the Athenian colonies of Pydna and Potidea. Shortly afterwards, the Third Sacred War began after the Phocian seizure of the Temple of Apollo in Delphi. Athens allied herself with Phocis, against the other members of the Amphictyonic League. In 354 or 353 BCE, the Thessalians, having been defeated by the Phocians, requested that Philip become archon of Thessaly, to which Philip assented, drawing Macedon into the Sacred War. In 352 BC, Philip's erstwhile ally, the Chalkidian League (led by Olynthos), alarmed by Philip's growing power, sought to ally themselves with Athens, in clear breach of their alliance with Philip. In response, Philip attacked Chalkidiki in 349 BC, and by 348 BC, had completely destroyed the Chalkidian League, razing Olynthos in the process.

Input: Consider Input: Question: When was the person born who wrote "Because You Loved Me"? Passage:A day following its impact on US radio stations, "Shake It Off" gained an audience of nine million. The song debuted at 45 on the Billboard Radio Songs chart with 29 million in all-format audience. It debuted on the Mainstream Top 40 chart at number 12, tying it with Mariah Carey's "Dreamlover" (1993) as the highest chart debut. "Shake It Off" became her third number-one song there, following her 2008 country crossover hit single "Love Story" and her 2013 hit "I Knew You Were Trouble", which remained No. 1 for seven consecutive weeks. The single debuted at number nine on the Billboard Adult Top 40 chart, becoming the highest debut single on the chart. On its sixth week, the song became her second No. 1 on the Adult Top 40 chart since her 2013 hit "I Knew You Were Trouble", tying it with Celine Dion's "Because You Loved Me" (1996) as the fastest song to reach number 1 in just six weeks. The song debuted at number 58 on the Country Airplay chart, though only two country stations played the song more than four times. It spent only one week on the chart. Billboard noted that its presence on the chart was unusual due to its sound and Swift's acknowledged transition from country to pop music. On the Radio Songs chart, the song became Swift's third number-one song there, following her 2013 hit "I Knew You Were Trouble". "Shake It Off" has spent four non-consecutive weeks at No. 1 on the Digital Songs chart.
