Example Input: Question: Which countries won gold medals at the two bobsleigh tracks constructed in Lake Placid? Passage 1:Constructed in 1930 for the 1932 Winter Olympics, the track was the first bobsleigh track located outside of Europe. In 1949, it hosted the FIBT World Championships, also the first outside of Europe. The original bobsleigh track was demolished in 1978 to pave the way for an artificial track for the 1980 Winter Olympics with a separate luge track being constructed for those same games. The luge track was the first luge track in North America when it was completed in 1979. In 1983, the luge track was the first venue to host the FIL World Luge Championships outside of Europe. Both tracks were demolished in the late 1990s and a combination track was constructed in early 2000 in time for the only Winter Goodwill Games. The track is a regular venue for World Cup competitions in bobsleigh, luge, and skeleton. In 2009, the track will become the first combination track to host the bobsleigh, luge, and skeleton world championships in a non-Winter Olympic year.
 Passage 2:In 1860, he ran for Canal Commissioner on the Douglas Democratic ticket, but was defeated by Republican Samuel H. Barnes. Barnes died a week after the election, and the vacancy was filled temporarily by the New York State Legislature in January 1861. Wright was the Democratic candidate, but was defeated by Republican Benjamin F. Bruce. In November 1861 he ran again, for the remaining two years of Barnes's term, and this time was elected defeating Bruce and War Democrat Frederick A. Tallmadge. He was in office from 1862 to 1863. In 1863, he ran for re-election, but was this time was defeated again by Bruce. In 1866, he ran again but was defeated by Republican Stephen T. Hayt. In 1869, he was elected again a Canal Commissioner, and was in office from 1870 to 1872.
 Passage 3:Other examples of mostly locally generated historical markers in the United States include the plaque outside the Alaska Governor's Mansion made by the Alaska Centennial Commission's historical markers program, the historical markers of State Historic Marker Council in Florida, the markers placed by various agencies in Georgia (of which one source mentions 3,292 different historical markers), in Indiana, where it is illegal to create a historical marker in the "state format" without first getting official approval from that state's historical bureau, historical markers in Kansas erected by the Kansas Historical Society and the Kansas Department of Transportation, the Roadside Historic Marker Program in Maryland administered by the Maryland Historical Trust, the State Historic Marker Program of New York (begun in 1926 to commemorate the Sequicentennial of the American Revolution), the historic markers placed as recently as 2008 in Sussex County, New Jersey, the New Mexico historical markers printed in white letters on a brown background by the New Mexico Department of Transportation, the historical markers of North Carolina (the Historical Publications Section of the state Office of Archives and History publishes a Guide to North Carolina Highway Historical Markers), the more than 1200 historical markers of Ohio (all of which are now made in a Marietta, Ohio workshop), and over 550 official state markers in Wisconsin.

Example Input: Question: Was the designer Long studied under at Yale born before 1940? Passage 1:Upon graduation from high school Long attended the College of William and Mary where he studied history and graduated in 1969, after spending many of his high school and undergraduate summers with his family at Manteo, North Carolina, where Mary, William, Robert, and Laura worked for Paul Green's outdoor drama, The Lost Colony. He then attended the University of North Carolina at Chapel Hill to pursue a Ph.D. in art history. At Chapel Hill he met visiting professor Betty Smith who suggested he apply to the design program at Yale University. He left UNC and went to the Yale School of Drama to study set design. It was here that he met Sigourney Weaver (his roommate at the time), Wendy Wasserstein, Meryl Streep, Christopher Durang, and Paul Rudnick, who were all also students at the university. While at Yale he studied under designer Ming Cho Lee, whom he has credited with being a major influence on his work.
 Passage 2:Diagnosis of MCC begins with a clinical examination of the skin and lymph nodes. Following, definitive diagnosis of Merkel cell carcinoma (MCC) requires examination of biopsy tissue to identify its histopathologic features. An ideal biopsy specimen is either a punch biopsy or a full-thickness incisional biopsy of the skin including full-thickness dermis and subcutaneous fat. On light microscopy, MCC shows basaloid tumor nests with neuroendocrine features ("salt and pepper" chromatin, scarce cytoplasm, and brisk mitotic activity). In addition to standard examination under light microscopy, immunohistochemistry (IHC) is also generally required to differentiate MCC from other morphologically similar tumors such as small cell lung cancer, the small cell variant of melanoma, various cutaneous leukemic/lymphoid neoplasms, and Ewing's sarcoma. Similarly, most experts recommend longitudinal imaging of the chest, typically a CT scan, to rule out that the possibility that the skin lesion is a skin metastasis of an underlying small cell carcinoma of the lung. Once an MCC diagnosis is made, a sentinel lymph node biopsy is recommended as a part of the staging work-up needed to determine prognosis and subsequent treatment options.
 Passage 3:Dekanozov studied in the medical schools of Saratov University and Baku University. In 1918 he entered the Red Army, and in 1920 he joined the Bolshevik Party. From 1918 he worked as a secret agent in Transcaucasia, first in the People's Commissariat for Health of the short-lived Azerbaijan Democratic Republic, then in private oil companies. After the invasion of Azerbaijan by the Red Army, Dekanozov worked for the Cheka of Azerbaijan SSR, where he befriended Lavrenty Beria, who subsequently supported Dekanozov. In 1921–27 Dekanozov worked for the Cheka in Azerbaijan, Georgia, and Transcaucasia. In 1927 he became an instructor of the Central Committee of the Communist Party of Georgia. In 1928–1931 he worked as one of the leaders of the Georgian and Transcaucasian OGPU. In 1931 he became a secretary of the Central Committee of the Communist Party of Georgia. From 1936 he was the Narkom of the food industry of Georgia, and from 1937 he simultaneously worked as the Chairman of Gosplan of Georgia and a deputy Chairman of Georgian Sovnarkom. He was a deputy of the Supreme Soviet of the USSR in 1937–50.

Example Input: Question: Who is currently holding the position of Commander of the Royal Canadian Air Force? Passage 1:John Cranch (1751–1821), painter, born at Kingsbridge, Devonshire, 12 Oct. 1751, taught himself as a boy drawing, writing, and music, and while a clerk at Axminster also received instruction from a Roman Catholic priest. Inheriting some money, he came to London and painted portraits and historical pictures. He failed, however, to get a place on the walls of the Royal Academy, but was more successful at the Society of Artists, to which he contributed Burning of the Albion Mills, and at the British Institution, to which he contributed eight pictures in 1808. His best picture was The Death of Chatterton, now in the possession of Sir James Winter Lake, bart., who also owns a portrait of Cranch, which was engraved by John Thomas Smith. He is said to have excelled in "poker-pictures", and to have been befriended by Sir Joshua Reynolds. Reynolds in his youth had received valuable assistance from a Mr. and Mrs. Cranch of Plympton, Devonshire, who were doubtless relatives of John Cranch. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1797 and a member of the American Antiquarian Society in 1818. After residing many years at Bath, Cranch died there in his seventieth year in February 1821. He published two works—On the Economy of Testaments (1794), and Inducements to promote the Fine Arts of Great Britain by exciting Native Genius to independent Effort and original Design (1811). There is a picture by him in the South Kensington Museum.

He travelled to the West Indies in 1939 and Canada where he joined the Canadian Army at the outbreak of World War II, but was invalided out in 1941. Back in Britain, he started as a sub-editor on the Daily Express, and later as a personal assistant to Manny Shinwell, a Labour MP, writing speeches for members of the party. In 1949 he became political columnist for the Daily Mirror, and unsuccessfully standing as a Labour party candidate for Bristol West in 1950 and 1951.
