Example Input: Question: Who was EA Games' CEO when Suda presented Kurayami's concept to the company? Passage:The game's history can be traced back to 2005, when Goichi Suda and Shinji Mikami (creator of the Resident Evil series) became good friends while working together on Killer7. Suda wanted to make a survival horror game exclusively for the PlayStation 3. With his first horror title  receiving decent sales in Japan by 2006, Suda immediately began working on Kurayami (Japanese for 'Darkness') in his spare time. It was at one time thought to be called "Closer". However, EA later confirmed that name had been abandoned for another title. By the Electronic Entertainment Expo (E3) in 2006, a publisher for Kurayami had not yet been established. In 2008, Suda presented the game's concept to EA Games, who agreed to license the Unreal Engine 3 and to publish the game to a worldwide audience. Shinji Mikami was then invited to executive-produce the project. Suda wanted to announce the game at E3 2009, but was not allowed to do so, due to a media silence agreement between Grasshopper Manufacture and EA Games. That December, Akira Yamaoka (sound designer for the Silent Hill series) left Konami after finishing his work on  and joined Grasshopper Manufacture because he enjoyed the latter's game No More Heroes. Yamaoka began work as the sound designer for the game. The game went about five different versions until Electronics Arts approved it. The newly titled Shadows of the Damned was finally unveiled at the Tokyo Game Show in 2010 as an action game.

Example Input: Question: What army did the USS Gunston Hall engage with during the assault on Kwajalein?  Passage:After intensive shakedown along the California coast Gunston Hall prepared to sail for the Western Pacific, where she was to participate in every major operation from February 1944 to the end of the war, 18 months later. Loading 225 men from the 4th Marine Tank Battalion and 2 amphibious units, as well as 15 LVTs, 15 tanks, 17 LCMs, and 15,000 gallons of gasoline, Gunston Hall departed San Diego on 13 January 1944. On D-Day for the assault on Kwajalein, 1 February 1944, she stood offshore to unload her cargo as the Marines stormed the beaches on Roi and Namur Islands. Gunston Hall remained in the area to repair small craft until 6 February, when she reembarked her former passengers and equipment and sailed to Guadalcanal via Funa Futi. The pattern she set here held for her participation in eight further key invasion efforts in the Pacific as the Navy "Island-hopped" marines and Army troops ever closer to the Japanese home islands.

Example Input: Question: Which location covered by Yamagumo during the invasion of the Philippines has a larger area? Passage:At the time of the attack on Pearl Harbor, Yamagumo, under the command of Lieutenant Commander Yasuji Koga, was flagship of the 3rd Special Attack Force in the invasion of the Philippines, covering landings at Camiguin Island and Lingayen. However, on 31 December, she suffered severe damage after striking a Japanese naval mine. She was towed to Hong Kong for repairs in early February, and then limped to Yokosuka Naval Arsenal by 7 April. She remained under repair until 15 May 1942 but remained based at Yokosuka through the end of August 1942. She made one escort mission to Saipan at the end of December 1942. In February 1943, while attempting to escort Tatsuta Maru to Truk, she was unable to prevent the former luxury liner from being torpedoed by the submarine with the loss of 1,400 lives just east-southeast of Mikurajima.
