Input: Question: How many nations comprise the organization that Albania complained to concerning Royal Navy conducting mine-clearing operations in Albanian territorial waters, Passage 1:The Corfu Channel Incident refers to three separate incidents involving Royal Navy ships in the Straits of Corfu which took place in 1946, and it is considered an early episode of the Cold War. During the first incident, Royal Navy ships came under fire from Albanian fortifications. The second incident involved Royal Navy ships striking mines and the third incident occurred when the Royal Navy conducted mine-clearing operations in the Corfu Channel, but in Albanian territorial waters, and Albania complained about them to the United Nations. This series of incidents led to the Corfu Channel Case, where the United Kingdom brought a case against the People's Republic of Albania to the International Court of Justice. Because of the incidents, Britain, in 1946, broke off talks with Albania aimed at establishing diplomatic relations between the two countries. Diplomatic relations were only restored in 1991.
 Passage 2:Bishop continued to act on film, TV and radio, usually in British and other European productions, and was a frequent guest at science fiction conventions. Bishop and fellow Anderson actor Shane Rimmer (a Canadian actor who often worked in the UK) often joked about how often their professional paths crossed and termed themselves "Rent-a-yank". They appeared together as NASA operatives in the opening of You Only Live Twice and as United States Navy sailors in The Bedford Incident, as well as the 1983 film of the Harold Robbins novel The Lonely Lady. In 1989, Bishop was reunited with Rimmer and another Anderson actor, Matt Zimmerman, in the BBC Radio 4 adaptation of Sir Arthur Conan Doyle's A Study In Scarlet. Bishop and Rimmer also toured together in theatre shows including Death of a Salesman in the 1990s and also appeared in the BBC drama-documentary Hiroshima (2005), one of Bishop's last TV projects.
 Passage 3:The game began shortly after 4 p.m. with Greg Maddux pitching for Atlanta and Masato Yoshii starting for the Mets. The Mets took an early 2–0 lead in the bottom of the first inning as John Olerud hit his second home run in as many days with Rickey Henderson on first. The lead lasted into the fourth inning, when Atlanta struck back with consecutive doubles by Bret Boone and Chipper Jones, eventually knotting the score at 2–2 when Brian Jordan singled home Jones. Mets Manager Bobby Valentine was immediately prompted to remove Yoshii from the game in favor of Orel Hershiser, which began a run on pitching changes that resulted in the Mets emptying their bullpen by game's end, relying on starter Kenny Rogers and rookie Octavio Dotel for key innings, and might have gone to Game 4's starter Rick Reed had the game progressed past the fifteenth inning. In all, the Mets used a postseason record nine pitchers in this game.
