Example Input: Question: What is the area code of the town where Milligan was born? Passage:Born in LaRue, Ohio, McMillan attended the Western College for Women and Westminster College in Pennsylvania. She then studied under George Luks and Hans Hofmann and at the Pratt Institute before traveling to Paris for further instruction with André Lhote and at the Fontainebleau School of Art. She is known to have been active in Washington, D.C. at least as early as 1931, continuing her activities there until at least 1967. Beginning in 1931, for over twenty years she taught painting and art history at the National Cathedral School, from which she retired in 1955. Long a member of the Arts Club of Washington, she had one-woman shows there in 1938 and 1947. Other solo shows occurred at George Washington University and at the Studio Gallery in New York City. She also belonged to the Society of Washington Artists, at whose 1932 exhibition she presented an oil titled Taos, New Mexico, and th Washington Water Color Club, and she exhibited with both the National Association of Women Artists and the National Association of Women Painters and Sculptors during her career. An article which she penned about the Society of Washington Artists was published in 1963 by the Columbia Historical Society. Milligan eventually moved to Tryon, North Carolina to join the artists' colony there. She died in Tryon; her body was returned to Ohio for burial, and rests in the Bellefontaine City Cemetery in Bellefontaine.

Example Input: Question: Was TJ Maxx a functioning company the year the Northpark Mall opened? Passage:Northpark Mall opened in 1972, on Range Line Road on the east side of Joplin. At the time, the mall was anchored by Montgomery Ward to the north, JCPenney to the south, and local chain Newman's the middle. Other stores included Walgreens, McCrory's, Ramsay's department store, For All Bible (which is still in business), Wyatts cafeteria, as well as many other stores. Newman's became Heer's in 1987, the same year that a new wing was built, and the mall received its first renovation. The new wing extended easterly from the JCPenney store. This new wing included two new anchors, Famous-Barr and Venture. The renovation also brought a food court as well as a new 5 screen cinema. In 1994, Heer's closed, and Famous-Barr moved its men's wear and home goods to the former Heer's space. That same year Sears built a store adjacent to Montgomery Ward, moving from an older store near downtown Joplin. In 1998 the mall received a minor renovation, changing only the color scheme. After the closure of the Venture chain in 1998, its anchor at the mall was converted to Shopko, but it closed in the early 2000s following the closure of Montgomery Ward in 2001. Both Famous-Barr locations were re-branded as Macy's in 2006. Montgomery Ward remained vacant until mid-2007, when its space was split between TJ Maxx and Steve & Barry's, the latter of which closed in 2008 and was replaced by Vintage Stock. In 2006 the mall received its first major renovation in nearly 20 years, changing the color scheme, adding all new lighting and floor tiles, and renovating the food court to a route 66 theme.

Example Input: Question: Is the fort that Runyon took more than 2,000 pictures of still operational? Passage:Runyon opened a commercial photography studio in 1910. He initially photographed urban life Brownsville and Matamoros, Tamaulipas and the surrounding terrain of the Rio Grande Valley. In 1913, Runyon began recording the events of the Mexican Revolution, starting with the takeover of the Matamoros garrison by the Constitutional Army under General Lucio Blanco on June 3. He traveled with Blanco's forces to Ciudad Victoria and later Monterrey. In 1915, Runyon was the only professional to photograph two skirmishes by Mexican bandits on American soil, the Norias Ranch Raid and a train derailment near Olmito, Texas. He took more than 2,000 pictures of Fort Brown, which captured troop buildup and mechanization in preparation for World War I. Runyon returned to more traditional subjects in the border region, as well as portraits and postcards, following the end of the war.
