Input: Consider Input: Passage: Seed spent the 191415 season playing in Sunderland reserves, he scored plenty of goals as the team lifted the Durham Senior Cup. Official League football was suspended at the end of that season because of the outbreak of World War I. At the end of the season, the 20-year-old Seed joined the Army Cyclist Corps. In the summer of 1916, he was drafted to France with the 8th battalion of the West Yorkshire Regiment. Seed suffered with depression after his arrival and in July 1917, he was gassed when a German aeroplane dropped mustard gas bombs on a house in Nieuwpoort, Belgium, in which he was sleeping. He returned to England to convalesce and returned to France in August 1918, until being evacuated after being gassed in Valenciennes, France two months later. With the cessation of hostilities, Seed played a Victory League match for Sunderland against Durham City in 1918, however his lungs were weak and he had a poor game. On the strength of that performance the Sunderland directors decided that Seed's wartime experience had finished him as a footballer and gave him a free transfer. Seed never played an official first team game for Sunderland. Seed was discharged from the army in March 1919.

Input: Consider Input: Passage: Little documentary evidence of Black Hoof's life appears in the historical record before 1795. As a child he may have been a member of a waundering band of some 400 Shawnees led by Peter Chartier between 1745 and 1748, who founded the community in Kentucky called Eskippakithiki and later moved to Sylacauga, Alabama, eventually settling in Old Shawneetown, Illinois. He probably took part in the Battle of Point Pleasant during Lord Dunmore's War against the Virginia militia in 1774. During the American Revolutionary War, he may have taken part in the siege of Boonesborough in 1778, which was led by Chief Blackfish, as well as the subsequent defense of the Shawnee village of Chillicothe in 1779. In the Northwest Indian War, Black Hoof was defeated by "Mad" Anthony Wayne and, following the collapse of the Indian confederation, surrendered in 1795.

Input: Consider Input: Passage: During the process of electing Leopoldo Calvo-Sotelo as Spain's new president in February 1981, Civil Guards and army members broke into the Congress of Deputies and held all deputies at gunpoint. One of the reasons that led to the coup d'etat was the increase of ETA's violence. The coup failed after the King called for the military powers to obey the Constitution. Days after the coup, ETA's faction politiko-militarra started its disbanding, with most of its members joining Euskadiko Ezkerra, a leftist nationalist party away from the Abertzale left. General elections were held in 1982, and Felipe Gonzalez, from the Socialist Workers' Party became the new president, while Herri Batasuna won two seats. In the Basque Country, Carlos Garaikoetxea from the PNV became lehendakari in 1979. During those years, hundreds of members of Herri Batasuna were arrested, especially after some of them sang the Eusko Gudariak in front of Juan Carlos I.
