Example Input: Question: Which team won more games the year Cowan started with the Rams, the Vikings or the Cowboys? Passage:Charles Edward Cowan (June 19, 1938 in Braeholm, West Virginia April 29, 1998 in Los Angeles, California) was an American football offensive tackle who played fifteen seasons in the National Football League with the Los Angeles Rams from 1961 to 1975. Cowan was a huge intimidating presence on the left of Tom Mack, a member of the Pro Football Hall of Fame, from 1966 to 1975, forming a potent left side of the offensive line, with help from Ken Iman at center from 1965 to 1975. In that 1961 to 1975 span, the Rams made the playoffs 5 times (1967,1969,1973,1974,1975), reaching the NFC championship game of the 1974-75 NFL playoffs and the 1975-76 NFL playoffs, but losing to the Minnesota Vikings and to the Dallas Cowboys, respectively. In the 1974 divisional round, the Rams defeated the Washington Redskins, as Cowan was successful against the opposing the right defensive end Verlon Biggs. In the 1975 divisional round, Doug France started in his place as the Rams defeated the St. Louis Cardinals. Cowan came back to play against the Cowboys, his final game, as the Rams could not get past them. Cowan was replaced by Doug France in 1976.

Example Input: Question: Does the college that Harrison graduated from in 1922 have more students than the one he graduated from in 1924? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.

Example Input: Question: What year was the company founded that created both show control and theatre sound design software which was used extensively in the theatre, theme park, display, exhibit, stage managing, show and themed entertainment industries in the 1980s and 1990s? Passage:Richmond Sound Design (RSD) created both show control (a.k.a. MSC or "MIDI Show Control") and theatre sound design software which was used extensively in the theatre, theme park, display, exhibit, stage managing, show and themed entertainment industries in the 1980s and 1990s and at one point in the mid 90s, there were many high-profile shows at major theme parks around the world being controlled by Amigas through software simply called Stage Manager which then evolved into its Microsoft Windows version called ShowMan. There were dozens at Walt Disney World alone and more at all other Disney, Universal Studios, Six Flags and Madame Tussauds properties as well as in many venues in Las Vegas including The Mirage hotel Volcano and Siegfried and Roy show, the MGM Grand EFX show, Broadway theatre, London's West End, the Royal Shakespeare Company's many venues, most of Branson, Missouri's theatres, and scores of theatres on cruise ships, amongst hundreds of others. RSD purchased used Amigas on the web and reconditioned them to provide enough systems for all the shows that specified them and only stopped providing new Amiga installations in 2000. There are still an unknown number of shows on cruise ships and in themed venues being run by Amigas.
