Passage: On 31 August, 2000, American citizen and Muslim convert Jeffrey Schilling from Oakland, California was captured on Jolo while visiting a terrorist camp with his new wife, Ivy Osani , whom he had met online. ASG demanded a $10 million ransom. Rebels also sarcastically threatened to behead him in 2001 as a "birthday present" to then Philippine President Gloria Macapagal Arroyo, who responded by declaring "all-out war" on them. The beheading threat was withdrawn after Schilling's mother, Carol, flew to the Philippines and appealed for mercy on local radio. On 12 April, 2001, Philippine soldiers raided a rebel camp and rescued the American. The United States praised the Philippine government for freeing Schilling. Many commentators have been critical of Schilling, who claims to have walked willingly into the camp after he was invited by his wife's cousin, a member of Abu Sayyaf. Schilling was one of more than forty hostages taken by Abu Sayyaf in 2000, including twenty-one tourists and workers seized in a raid on Sipadan diving resort in neighbouring Malaysia. Many of the hostages were released after Libya paid millions of dollars. A Libyan official stated that Schilling had visited the Jolo camp often before his capture. Philippine intelligence sources say he was interested in selling military equipment to the rebels, while the bandits accused him of being a CIA agent. Abu Sayyaf threatened several times to kill Schilling. At one stage, Schilling reportedly went on a hunger strike to win his freedom.
Question: What date were 21 tourists taken hostage by Abu Sayyaf?

Ex Output:
date

Passage: The Greco-Turkish War of 1919-1922 was fought between Greece and the Turkish National Movement during the partitioning of the Ottoman Empire after World War I between May 1919 and October 1922. It is known as the Western Front  of the Turkish War of Independence in Turkey and the Asia Minor Campaign  or the Asia Minor Catastrophe  in Greece. The Greek campaign was launched primarily because the western Allies, particularly British Prime Minister David Lloyd George, had promised Greece territorial gains at the expense of the Ottoman Empire, recently defeated in World War I. The armed conflict started when the Greek forces landed in Smyrna , on 15 May 1919. They advanced inland and took control of the western and northwestern part of Anatolia, including the cities of Manisa, Balıkesir, Aydın, Kütahya, Bursa and Eskişehir. Their advance was checked at the Battle of Sakarya in 1921 by forces of the Turkish national movement. The Greek front collapsed with the Turkish counter-attack in August 1922, and the war effectively ended with the recapture of Smyrna by the Turkish forces and the Great Fire of Smyrna. As a result, the Greek government accepted the demands of the Turkish national movement and returned to its pre-war borders, thus leaving East Thrace and Western Anatolia to Turkey. The Allies abandoned the Treaty of Sèvres to negotiate a new treaty at Lausanne with the Turkish National Movement. The Treaty of Lausanne recognized the independence of the Republic of Turkey and its sovereignty over Asia Minor, Constantinople, and Eastern Thrace. Greek and Turkish governments agreed to engage in a population exchange.
Question: For how many years did the Greco-Turkish war last?

Ex Output:
number
