Input: Question: When were the canceled Apollo Moon landings supposed to take place? Passage 1:Strout's first novel, Amy and Isabelle (1998) met with widespread critical acclaim, became a national bestseller, and was adapted into a movie starring Elisabeth Shue. Her second novel, Abide with Me (2006), received critical acclaim but ultimately failed to be recognized to the extent of her debut novel. Two years later, Strout wrote and published Olive Kitteridge (2008), to critical and commercial success grossing nearly $25 million with over one million copies sold as of May 2017. The novel won the 2009 Pulitzer Prize for Fiction. The book was adapted into a multi Emmy Award-winning mini series and became a New York Times bestseller. Five years later, she published The Burgess Boys (2013), which became a national bestseller. My Name Is Lucy Barton (2016) was met with international acclaim and topped the New York Times bestseller list. Lucy Barton later became the main character in Strout's 2017 novel, Anything is Possible. A sequel to Olive Kitteridge, titled Olive, Again, was published in 2019.
 Passage 2:The early history of United States space policy is linked to the US–Soviet Space Race of the 1960s. The National Aeronautics and Space Act creating NASA was passed in 1958, after the launch of the Soviet Sputnik 1 satellite. Thereafter, in response to the flight of Yuri Gagarin as the first man in space, Kennedy in 1961 committed the United States to landing a man on the Moon by the end of the decade. Although the costs of the Vietnam War and the programs of the Great Society forced cuts to NASA's budget as early as 1965, the first Moon landing occurred in 1969, early in Richard Nixon's presidency. Under the Nixon administration NASA's budget continued to decline and three of the planned Apollo Moon landings were cancelled. The Nixon administration approved the beginning of the Space Shuttle program in 1972, but did not support funding of other projects such as a Mars landing, colonization of the Moon, or a permanent space station.
 Passage 3:The Philadelphia Phillies–Florida Marlins game began at 7:13 p.m. on May 29, 2010, to a crowd of 25,086 at Sun Life Stadium in Miami. The home plate umpire was Mike DiMuro, the first base umpire was Tim Welke, the second base umpire was Jim Reynolds, and the third base umpire was Bill Welke. Roy Halladay pitched the 20th perfect game in MLB history, retiring all 27 batters, and allowing no hits, no runs, and no errors. Although he is known as a ground ball pitcher, he struck out 11, his most of the year and the most by a Phillies pitcher at that point in the season. The opposing pitcher, Josh Johnson, allowed seven hits, one walk, and an unearned run in seven innings. The unearned run came in the top of the third, when Chase Utley's line drive bounced off the glove of Florida center fielder Cameron Maybin, allowing Wilson Valdez to score from first. This was the deciding factor in the game, for Josh Johnson did not allow another run for the duration of the game.
