Input: Question: How many lives were lost in the war in which Carpenter flew reconnaissance and anti-submarine warfare missions in Japan? Passage 1:After three months at the Fleet Airborne Electronics Training School in San Diego, California, Carpenter went to a Lockheed P-2 Neptune transitional training unit at Whidbey Island, Washington, after which he was assigned to Patrol Squadron 6 (VP-6), based at Naval Air Station Barbers Point, Hawaii, in November 1951. On his first deployment, Carpenter flew on reconnaissance and anti-submarine warfare missions from Naval Air Station Atsugi in Japan during the Korean War. On his second deployment, forward-based at Naval Air Facility Adak, Alaska, he flew surveillance missions along the Russian and Chinese coasts. For his third and final deployment, he was based on Guam, flying missions off the coast of China. He was designated as patrol plane commander, the only one in VP-6 with the rank of lieutenant (junior grade)all the rest held higher rank.
Passage 2:Zaire was soon translated into English by Aaron Hill as Zara: A Tragedy. Following its successful run at London's Drury Lane Theatre in 1736, Zara became the most frequently staged English adaptation of a Voltaire play. Famous English actresses who have played the title role include Susannah Maria Cibber, who made her stage debut in the 1736 Drury Lane production, Sarah Siddons, and Elizabeth Younge. The first known professional performance of the play in the American Colonies was in Philadelphia on 26 December 1768, performed by the Hallam Company using the Aaron Hill version. The company took the play to New York City in 1769 and after the end of the Revolutionary War sporadically revived it there and in Philadelphia. The first professional performances after the hostilities ended were given in Baltimore in April 1782 by the Thomas Wall Company. Although the professional theatres were closed during the War, the play proved popular with the British Army. General Burgoyne, himself a playwright, produced Zara with military actors in British-occupied Boston in 1775 and four times in occupied New York between 1780 and 1781.
Passage 3:The wintering migrant birds which flock to the sanctuary were recorded at different periods during the winter months. The early arrivals in October were gadwall (Aythya ferina), northern pintail (Anas acuta), northern shoveller (Anas clypeata), common teal (Anas crecca), common pochard (Aythya ferina), and common coot (Fulica atra). The birds recorded during November were mallard (Anas platyrhynchos), spot-billed duck (Anas poecilorhyncha), and knob-billed duck (Sarkidiornis melanotos). The departure of the birds from the sanctuary was also noted in different months, towards the end of the winter season. The summer birds recorded were the lesser whistling duck (Dendrocygna javanica) and the cotton teal (Nettapus coromandelianus).
