Question: When did the event where  Frank Alberry won a Distinguished Conduct Medal end? Passage:Frank Alberry, DCM (29 September 1892 – 23 January 1968) was an Australian soldier and airman who had a varied military career. Born in Hobart, he served in the Welch Regiment of the British Army before the First World War, but deserted. He joined up again in the early days of the First World War, and went on to serve with the 8th Battalion of the Australian Imperial Force. After service at Gallipoli, he joined the British Expeditionary Force in France. He won a Distinguished Conduct Medal at the Battle of Pozières, but lost a lower leg in the process. Alberry took the extraordinary step of personally petitioning King George V for permission to transfer to the Flying Corps, and subsequently became a flying ace credited with seven aerial victories. Alberry returned to service during the Second World War as a recruiter.

Question: What is the common English word for the name of the place containing inhabitants allowed to take part in the festival? 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.
