Question: Besides Umbriel, what are the names of the moons that orbit Uranus? Passage:Umbriel orbits Uranus at the distance of about , being the third farthest from the planet among its five major moons. Umbriel's orbit has a small eccentricity and is inclined very little relative to the equator of Uranus. Its orbital period is around 4.1 Earth days, coincident with its rotational period. In other words, Umbriel is a synchronous or tidally locked satellite, with one face always pointing toward its parent planet. Umbriel's orbit lies completely inside the Uranian magnetosphere. This is important, because the trailing hemispheres of airless satellites orbiting inside a magnetosphere (like Umbriel) are struck by magnetospheric plasma, which co-rotates with the planet. This bombardment may lead to the darkening of the trailing hemispheres, which is actually observed for all Uranian moons except Oberon (see below). Umbriel also serves as a sink of the magnetospheric charged particles, which creates a pronounced dip in energetic particle count near the moon's orbit as observed by Voyager 2 in 1986.

Question: Where in Kentucky is the race held in which Parole finished 4th in 1876? Passage:An avid sportsman, Pierre Lorillard and his brother, George Lyndes Lorillard, were both major figures in Thoroughbred horse racing. In 1874, Pierre's horse, Saxon, won the Belmont Stakes. Although his horse Parole finished fourth in the 1876 Kentucky Derby, it went on to race with considerable success both in the United States and in Europe. In the 19th century, shipping horses from New York to Louisville, Kentucky was a major undertaking and as the Preakness Stakes and the Belmont Stakes were both held in the New York City area in the period, neither of the Lorillard brothers entered horses again in the Kentucky Derby. Pierre Lorillard established Rancocas Stable, named for the New Jersey town where he owned a country house. He spent time in Paris and in England where, in 1881, his horse Iroquois became the first American-owned and bred horse to win a European classic race. Ridden by the champion English jockey Fred Archer, Iroquois won The Derby and then went on to capture the St. Leger Stakes as well. Lorillard had other successes in England, notably with the horse named for the actor David Garrick, which won the 1901 Chester Cup ridden by American jockey, Danny Maher.

Question: How many years after Chicago Air went defunct was Chicago Express Airlines established? Passage:The airline was established in 1993 by Mike Brady of Express Airlines I in Atlanta, Georgia. The airline started operations in August 1993. Its route structure in many ways mimiced an unrelated defunct predecessor named Chicago Air which also operated from Chicago Midway's airport less than a decade before. On June 1, 1999, Chicago Express became a wholly owned subsidiary of Amtran, later known as ATA Holdings and now Global Aero Logistics, and operated as ATA Connection, a regional code sharing affiliate of the now defunct ATA Airlines (formerly known as American Trans Air). Chicago Express' principal base of operations was Chicago Midway International Airport, where the company maintained its headquarters. For several months before its liquidation, the company also operated a hub in Indianapolis, part of ATA's failed plan for intrastate flights throughout Indiana. However, following ATA Holdings' decision to codeshare flights with Southwest Airlines, a decision was made to terminate Chicago Express effective March 28, 2005, in favor of a strictly mainline operation. CSC Investment Group, Inc., headed by CEO Edward S. Halley, purchased the airline in 2005 for $3.2 million.
