Input: Consider Input: Question: How many miles would the Empire Nightingale travel when crossing the Atlantic Ocean to Yorkshire? Passage:Empire Nightingale would appear to have crossed the Atlantic Ocean from the United States independently, as she does not appear as a member of a convoy until 27 June, when she departed Middlesbrough, Yorkshire as a member of Convoy EC 31. The convoy had departed from Southend, Essex the previous day and arrived at the Clyde on 1 July. She left the convoy at Oban, Argyllshire, departing on 3 July for Baltimore, Maryland, United States, which was reached on 22 July. Empire Nightingale departed Baltimore on 10 August for Halifax, Nova Scotia, Canada, arriving five days later. Carrying a cargo of steel, she departed on 21 August with Convoy HX 146, which arrived at Liverpool, Lancashire on 6 September.

Input: Consider Input: Question: In what years did the Calgary Dinos win the Vanier Cup? Passage:During the following off-season in 2015, UBC Athletics would draw the Dinos head coach, Blake Nill away from the Calgary Dinos in what was the most high profile coaching change that year. Nill's impact was immediate as he was able to recruit quarterback Michael O'Connor, who was the ranked the sixth best quarterback by ESPN among the 2014 recruiting class. The Thunderbirds achieved a turnaround in Nill's debut season at the UBC helm to finish the 2015 regular season with a 62 record, placing second in the CWUAA standings. During the ensuing post-season drive of three straight single-elimination playoff games on the road, UBC upset the heavily favoured Calgary Dinos in the Hardy Cup game at Calgary; then defeated the St. Francis Xavier X-Men to earn its historical first Uteck Bowl victory at Antigonish, to advance to the national title game. In the 51st Vanier Cup championship, the Thunderbirds narrowly defeated the defending CIS champion Montreal Carabins, by scoring the game's last possession field goal to end the fourth quarter. The victory was UBC's fourth Vanier Cup overall, tying the Calgary Dinos for the all-time record among CWUAA member universities.
