Task: Question Generation
Input (English): Passage: Despite the fall of Athens, Morosini's position was not secure. The Ottomans were amassing an army at Thebes, and their 2,000-strong cavalry effectively controlled Attica, limiting the Venetians to the environs of Athens, so that the Venetians had to establish forts to secure the road linking Athens to Piraeus. On 26 December, the 1,400-strong remnant of the Hannoverian contingent departed, and a new outbreak of the plague during the winter further weakened the Venetian forces. The Venetians managed to recruit 500 Arvanites from the rural population of Attica as soldiers, but no Greeks were willing to join the Venetian army. In a council on 31 December, it was decided to abandon Athens and focus on other projects, such as the conquest of Negroponte. A camp was fortified at the Munychia to cover the evacuation, and it was suggested, but not agreed on, that the walls of the Acropolis should be razed. As the Venetian preparations to leave became evident, many Athenians chose to leave, fearing Ottoman reprisals: 622 families, some 4,000-5,000 people, were evacuated by Venetian ships and settled as colonists in Argolis, Corinthia, Patras, and Aegean islands. Morosini decided to at least take back a few ancient monuments as spoils, but on 19 March the statues of Poseidon and the chariot of Nike fell down and smashed into pieces as they were being removed from the western pediment of the Parthenon. The Venetians abandoned the attempt to remove further sculptures from the temple, and instead took a few marble lions, including the famous Piraeus Lion, which had given the harbour its medieval name "Porto Leone", and which today stands at the entrance of the Venetian Arsenal. On 10 April, the Venetians evacuated Attica for the Peloponnese.
Output (English): How many people from Attica that joined up were Greeks?
