Input: Question: What are the other names of two-seat night fighter planes used by the Royal Air Force? Passage 1:Anderson did not play again on tour until May at the Madrid Open. He lost in the first round against 13th seed Gael Monfils. Anderson then played in Rome as the 16th seed. Anderson won his first-round match against Feliciano Lopez, but lost in the second round to Juan Monaco, despite winning the first set. Anderson then competed in Nice as the third seed. He defeated qualifier Diego Schwartzman, before losing to fifth seed Joao Sousa. Anderson then played at the French Open as the 18th seed, where he lost in the first round to Stephane Robert. Anderson started his grass season at Queen's Club. Since he entered late, he had to go through qualifying. Anderson defeated Edward Corrie and Jiri Vesely, both in straight sets, to enter the main draw. He then lost to Bernard Tomic in the first round of the main draw. Anderson then played at Nottingham as the top seed. He defeated Ivan Dodig and 14th seed Fernando Verdasco to reach the quarterfinals, where he lost to sixth seed and eventual champion Steve Johnson. Anderson then played at Wimbledon as the 20th seed. He lost in the first round to Denis Istomin, despite winning the first two sets.
Passage 2:Christopher William "Will" Gill, BFA (born July 5, 1968) is a Canadian contemporary artist known for his wide-ranging works in sculpture, painting, photography and video. Born and raised in Ottawa, Ontario, Canada, he received his Bachelor of Fine Arts in 1991 from Mount Allison University, where he studied sculpture and printmaking. In 1997 he moved to St. John's, Newfoundland. "Some of Gill's notable works have drawn upon the Newfoundland landscape. In the 2009 performance Cape Spear, he tossed fibreglass-encased glow sticks off of the easternmost point of North America using a catapult." "The 2009 installation Bareneed is a replica of a cast-iron bathtub that Gill saw on the bottom of the ocean floor while sea-kayaking near the titular coastal community (the artist himself has noted that the St. John's setting has been key to his art production)." Gill was longlisted for the Sobey Art Award in 2004 and 2006. In March 2013, Gill was selected from a group of 31 artists to create an indoor public art installation in the lobby of a new office building in St. John's, set to open in the spring of 2014 - the first private juried art commission in the province awarded to a local artist. From June to November 2013 he exhibited along with artist Peter Wilkins as part of an official Collateral Project at the 2013 Venice Biennale.
Passage 3:The Venom entered service with the Royal Air Force (RAF), where it was used as a single-seat fighter-bomber and two-seat night fighter. A dedicated model for aerial reconnaissance was also operated by the Swiss Air Force. The Venom functioned as an interim stage between the first generation of British jet fighters straight-wing aircraft powered by centrifugal flow engines such as the Gloster Meteor and the Vampire and later swept wing, axial flow-engined combat aircraft, such as the Hawker Hunter and de Havilland Sea Vixen. Accordingly, the type had a relatively short service life in the RAF, being withdrawn from frontline operations by the service in 1962 as a result of the introduction of more capable designs. However, it was used in combat during the Suez Crisis, the Malayan Emergency, and the Aden Emergency.
