Input: Consider Input: Question: On what date did Apollo 11 land at it's destination site? 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.

Input: Consider Input: Question: Besides the Army of Conde, what were the other emigre field armies during the French Revolutionary War? Passage:The Army of Condé () was a French field army during the French Revolutionary Wars. One of several émigré field armies, it was the only one to survive the War of the First Coalition; others had been formed by the Comte d'Artois (brother of King Louis XVI) and Mirabeau-Tonneau. The émigré armies were formed by aristocrats and nobles who had fled from the violence in France after the August Decrees. The army was commanded by Louis Joseph de Bourbon, Prince de Condé, the cousin of Louis XVI of France. Among its members were Condé's grandson, the Duc d'Enghien and the two sons of Louis XVI's younger brother, the Comte d'Artois, and so the army was sometimes also called the Princes' Army.
