Input: Consider Input: Question: What city is to the south of the location where Curtis was born? Passage:Curtis was born at Coddington, Herefordshire in 1872, the youngest of the four children of an Anglican rector. He was educated at Haileybury College and then at New College, Oxford, where he read law. He fought in the Second Boer War with the City Imperial Volunteers and served as secretary to Lord Milner (a position that had also been held by adventure-novelist John Buchan), during which time he dedicated himself to working for a united self-governing South Africa. Following Milner's death in 1925, he became the second leader of Milner's Kindergarten until his own death in 1955. His experience led him to conceptualize his version of a Federal World Government, which became his life work. In pursuit of this goal, he founded (1910) the quarterly Round Table. He was appointed (1912) Beit lecturer in colonial history at the University of Oxford, and a Fellow of All Souls College.

Input: Consider Input: Question: Was the driver of the No. 95 car in 2019 married at the time he signed a contract with Leavine Family Racing? Passage:On October 10, 2018, Matt DiBenedetto signed a two-year contract with Leavine Family Racing to drive the No. 95 starting in 2019. In addition, Leavine Family Racing will switch from Chevrolet to Toyota while entering a technical alliance with Joe Gibbs Racing. At the 2019 Daytona 500, DiBenedetto led an impressive 49 laps before Paul Menard spun him from behind, triggering "The Big One" that claimed 21 cars and resulting in DiBenedetto finishing 28th. DiBenedetto scored a career-high fourth place finish at Sonoma. DiBenedetto then scored four more top 10s in the summer months including an eighth at Daytona, a fifth at Loudon, a sixth at Watkins Glen, and a career-high second for both DiBenedetto and Leavine Family Racing at the Bristol Night Race.

Input: Consider Input: Question: Which of the three craters seen on the east side of Mare Tranquillitatis is the largest? Passage: are three views of Mare Tranquillitatis on the Moon, taken by the mapping camera of the Apollo 17 mission in 1972, facing south-southwest from an average altitude of 111 km on Revolution 36 of the mission. At the left is the east side of Mare Tranquillitatis, with the craters Franz (bottom right), Lyell (dark floor, right of center), and Taruntius (upper left). The "bay" of dark mare (basalt) at left is Sinus Concordiae, with "islands" of older, light highland material. At the right is the crater Cauchy, which lies between the Rupes Cauchy and Cauchy rille. The center photo shows the central mare with craters Vitruvius (lower right) and Gardner (bottom center). At the horizon are lighter highlands at the southern margin of the mare, near the Apollo 11 landing site. The crater Jansen is visible at the edges of both the center and right photos. The right photo shows the western mare, with the craters Dawes (lower left) and the large Plinius (43 km diameter), with the Plinius Rilles in the foreground. These photos were taken within minutes of each other as the command module America orbited the Moon. The Sun elevation drops from 46 degrees at left to 30 degrees at right.
