[EX Q]: Question: Who managed the team just prior to the current manager? Passage:The 2019–20 season is Port Vale's 108th season of football in the English Football League, and third consecutive season in EFL League Two. It is the first full season under manager John Askey and new owners Carol and Kevin Shanahan. The season covers the period from 1 July 2019 through to 30 June 2020. Askey reshaped the squad by letting 14 players go and bringing in 14 new signings, though David Amoo was the only new player in the starting eleven for the opening game of the season. They lost just one league game in six matches in August, though this was a heavy 5–2 defeat at Grimsby Town, and they also exited the EFL Cup at the first round. September saw them in indifferent form, as they picked up just one league win, though Vale did secure their place in the knockout stages of the EFL Trophy. October saw more promise, as they picked up their first away win, though were held to disappointing draws at home to struggling teams. They went on to claim five wins in six games in the month of November, including a 1–0 victory at local rivals Crewe Alexandra and wins against Milton Keynes Dons and Cheltenham Town in the FA Cup.

[EX Q]: Question: Which city was larger the year Cowan was born, Braeholm or Los Angeles? 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.

[EX Q]: Question: What year did the 15th century chronicler and antiquary that documented Hotwells springs die? Passage:Hotwells takes its name from the hot springs which bubble up through the rocks of the Avon Gorge underneath the Clifton Suspension Bridge. The springs were documented in 1480 by William Worcester, the 15th century chronicler and antiquary. He described the waters as being milky and as warm as those at Bath. In 1692 the Society of Merchant Venturers leased the springs and a pump room was built. The pump room of 1696 was demolished and replaced by Hotwells House in 1816 which was itself demolished when the river was widened in 1867. In the Georgian era, Hotwells was developed as a spa including the building of Dowry Square in an attempt to compete with Bath. Many visitors came, including the diarist John Evelyn and the travel writer Celia Fiennes, who hunted for Bristol Diamonds in the gorge. The Somerset historian John Collinson came to Hotwells in 1793 seeking recovery from an unspecified lingering illness and died there on 27 August 1793.
