Example 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.

Example Input: Question: What year did the war end in which Hayashi Tadataka was at Joza? Passage:With the start of the Boshin War, Hayashi Tadataka was at Jozai, and though he was not able to participate in the Battle of TobaFushimi, he set himself apart from all other fudai lords in that he invoked his hereditary obligation to the Tokugawa clan in going to war. Taking part in the guerrilla warfare efforts of Hitomi Katsutaro, Tadataka departed his domain with his entire retainer force, and fought from Izu Province all the way north to Aizu and Sendai as part of the Ouetsu Reppan Domei, finally surrendering when he received news that the main Tokugawa family had been given a fief at Sunpu (modern-day Shizuoka), in Suruga Province. However, in punishment for Tadataka's actions, Jozai was taken over by the new government. Tadataka himself was placed in confinement at the Edo residence of the Ogasawara family of Karatsu, of which his family was a branch line. He was later released, and held several government positions before his retirement, and was also made a baron (danshaku) in the kazoku peerage. Hayashi Tadataka was the last of the former daimyos to die, in 1941.
