Example Input: Question: How many years had the American Revolution been ongoing when the British evacuated Boston? Passage:Benjamin Thompson was a Loyalist during the American Revolution, and fled the country in 1775 when the British evacuated Boston. He returned late in the Rev War commanding the King's American Dragoons, who saw action in the Southern states. He returned to England after the British surrender. He eventually settled for a time in the Holy Roman Empire, where he acquired the title of Count Rumford, and where he performed his groundbreaking research into the design of heating systems. This research resulted in a series of improvements to home heating systems, notably the Rumford stove, a shallow fireplace that more efficiently projected heat into a room than older and larger fireplaces. While in Munich, Thompson oversaw reforms of the indigent welfare system of Bavaria, and designed the city's famous English Garden. Thompson was also an inveterate and practical tinkerer, developing new versions of everyday utensils. He also proposed in 1799 the establishment in the United Kingdom of a research organization, which resulted in the founding of the Royal Institution. Although he never returned to the country of his birth, he did endow a professorial chair at Harvard College, and established the Rumford Prize, an annual award given by the American Academy of Arts and Sciences. He died in Paris in 1814.

Example Input: Question: How many total albums have the Swedish pop group ABBA released? Passage:The Definitive Collection is a 2001 compilation album of all the singles released by Swedish pop group ABBA. It consisted of two discs: the first featuring the singles from 197279 ("People Need Love" to "Does Your Mother Know"), and the second including the singles from 197982 ("Voulez-Vous" to "Under Attack"), with the tracks being listed in chronological order. The main exception is the track "Thank You for the Music", which, despite being written and recorded in 1977, was in fact released as a single (primarily in the UK) in 1983 after the band had split up. It appears on disc two, along with two bonus tracks, "Ring Ring" (1974 UK single remix), and "Voulez-Vous" (1979 US promo extended remix). The Australian version of The Definitive Collection adds a further two bonus tracks: "Rock Me" and "Hasta Manana". The 1974 remix of "Ring Ring" is the first appearance on CD of this version mastered from the original master tape, after the UK single master tapes had been returned to Polar Music by the former UK licensees, Epic Records. The track's previous appearance on CD, in a 1999 singles boxed set, was mastered from a vinyl single.

Example Input: Question: How many years had Kate Bornstein been an author when she appeared on the Melissa Harris-Perry show? Passage:In April 2012, author Kate Bornstein spoke about McDonald on MSNBC cable television program Melissa Harris-Perry, comparing McDonald's situation with George Zimmerman's in the aftermath of the shooting of Trayvon Martin regarding self-defense issues and how the case is viewed through the media focus. The case also attracted national attention from LGBT activists including author Leslie Feinberg, who wrote that "the right of self-defense against all forms of oppressionsthe spirit of Stonewallis at the heart of the demand to free [McDonald]". Cam Gordon, a member of the Minneapolis City Council, announced his support for McDonald and called the incident "another example [of] transgender women of color being targeted for hate- and bias-related violence", and Susan Allen, a member of the Minnesota House of Representatives, called on Freeman to consider the "extenuating circumstances" of McDonald's case. In May 2013, an article by Marc Lamont Hill for Ebony.com entitled "Why Aren't We Fighting for CeCe McDonald?" won the GLAAD Media Award for "Outstanding Digital Journalism Article". McDonald also received the support of transgender activist and actress Laverne Cox, who stars in the television series Orange Is the New Black.
