Question: Which war lasted longer, the Greco-Turkish War of 1897 or the Blakan Wars? Passage 1:Born to an aristocratic family in Ithaca, Metaxas took part in the Greco-Turkish War of 1897 and the Balkan Wars (1912–13), quickly rising through the ranks of the Hellenic Army. A royalist during the National Schism, Metaxas unsuccessfully opposed Prime Minister Eleftherios Venizelos and Greece's entry in World War I; as a result, he was exiled to Corsica in 1917. On his return, Metaxas moved into politics and founded the Freethinkers' Party, but had only limited success under the Hellenic Republic. The Greek monarchy was restored in 1935, and Metaxas was appointed Prime Minister in April 1936. On 4 August 1936, with the support of King George II, Metaxas initiated a self-coup and established an authoritarian, nationalist and anti-communist regime.
 Passage 2:USS Butternut departed Leyte Gulf in convoy on 24 February 1947 and shaped a course for the Marianas. She arrived at Guam on 9 March and began three years of service in the Trust Territories of the Pacific Ocean Islands. Based at Apra Harbor on Guam, she carried passengers and cargo among the islands as well as laying and tending nets at various islands. The ship also performed several assignments off Iwo Jima laying mooring buoys and assisting in the recovery, repair and replacement of submarine lines. the ship departed Guam on 19 June 1950 for repairs at the Pearl Harbor Naval Shipyard. The net laying ship completed repairs and put to sea on 15 September. Steaming via Guam and Iwo Jima, she arrived in Sasebo, Japan, on 28 October. The ship conducted operations at Sasebo and Yokosuka, Japan, until 7 July 1951 when she set sail for Guam to resume her former duties in the Trust Territories.
 Passage 3:The Story Mound is a Native American mound in the southwestern part of the U.S. state of Ohio. Located in the Sayler Park neighborhood of the city of Cincinnati, the mound lies along Gracely Drive. No archaeological excavation has ever been conducted at the mound, and it has remained otherwise undisturbed as well; consequently, the mound remains in pristine condition. Despite the lack of evidence from excavations, the mound has been determined to be a work of the Adena culture, due in part to artifacts such as bones that have been found in the land immediately surrounding the mound. These findings, together with the mound's location near the floodplain of the Ohio River, have been understood as evidence of a larger group of Adena sites in the vicinity of the Story Mound. Such a complex, if it exists, would have great value as an archaeological site; therefore, the Story Mound was listed on the National Register of Historic Places in 1975.
