Input: Consider Input: Question: Which rolling stock did the Turboliner replace? Passage:Following its takeover of most passenger rail service in the United States on May 1, 1971, Amtrak retained the Abraham Lincoln as a daily Chicago-St. Louis service, operating in tandem with the GM&O's old Limited. In November of that year Amtrak extended both the Abraham Lincoln and the Limited (now known as the Prairie State) through Chicago to Milwaukee, Wisconsin. In October 1973, Amtrak replaced the rolling stock with the new French-built Turboliner; as part of this change the trains were re-branded as Turboliners and truncated to Chicago. In February 1976 Amtrak returned conventional rolling stock to the route and revived the Abraham Lincoln name along with the Ann Rutledge. Amtrak added the State House to the Chicago-St. Louis corridor in 1977. Also in 1977, Amtrak extended the Abraham Lincoln to Kansas City and renamed it the Ann Rutledge–a name that had briefly disappeared from the timetable in 1976-77 when Amtrak extended the Inter-American to Chicago. Today service between Chicago and St. Louis is handled by the "Lincoln Service".

Input: Consider Input: Question: What character did THompkins voice in Dr. Katz, Professional Therapist? Passage:Tompkins has done voice work for many animated television series including Dr. Katz, Professional Therapist, King of the Hill, and Bob's Burgers, in which he voices the recurring character Randy. He lent his voice to a character in an unaired 2007 episode of Aqua Teen Hunger Force titled "Boston" that was supposed to be the premiere episode of the show's fifth season, but it was pulled by Turner Broadcasting System to avoid further controversy surrounding the 2007 Boston bomb scare. Tompkins later appeared in an episode during the show's 7th season. He was also the voice of one of the thugs in Walt Disney Animation Studios' 2010 computer animated film Tangled. Tompkins was the voice of Benton Criswell, a character in MTV series Super Adventure Team which featured marionettes in the style of the 1960s British series Thunderbirds; the role was credited under the stage name Francis Mt. Pleasant. He was the voice of a puppet in ads for the Ford Focus. Tompkins plays Mr. Peanutbutter in the 2014 Netflix original animated series BoJack Horseman. Tompkins voices the recurring character, Gladstone Gander, in the reboot series of DuckTales.

Input: Consider Input: Question: Of the homes built in the historic district during the antebellum period, which style is older? Passage:The George S. Houston Historic District is a historic district in Athens, Alabama. The district lies to the west and north of the public square, and features homes of some of the town's most prominent residents. Development began in the district soon after the town was founded in 1818; there are five homes remaining from the antebellum period. The district saw moderate growth between the Civil War and the early 1900s, most of which are Queen Anne and Victorian styles. The majority of houses in the district were constructed between 1908 and 1939. As the need for housing in the town grew, larger antebellum lots were subdivided and new construction was added. Larger houses tended to be American Foursquares, while middle-class houses were bungalows and cottages, some with Tudor Revival and Colonial Revival details. The district is entirely residential, with the exception of the First Methodist Church, built in 1925 in Neoclassical style; 400 North Jefferson was built in 1935 as a hospital, but later converted to apartments. Other notable properties in the district include the George S. Houston House, which was converted into a public library. The district was listed on the National Register of Historic Places in 1989.
