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.

Input: Consider Input: Question: Which states aided the Latin Empire under the benner "Crusader States"? Passage:The NicaeanLatin wars were a series of wars between the Latin Empire and the Empire of Nicaea, starting with the dissolution of the Byzantine Empire by the Fourth Crusade in 1204. The Latin Empire was aided by other Crusader states established on Byzantine territory after the Fourth Crusade, as well as the Republic of Venice, while the Empire of Nicaea was assisted occasionally by the Second Bulgarian Empire, and sought the aid of Venice's rival, the Republic of Genoa. The conflict also involved the Greek state of Epirus, which also claimed the Byzantine inheritance and opposed Nicaean hegemony. The Nicaean reconquest of Constantinople in 1261 AD and the restoration of the Byzantine Empire under the Palaiologos dynasty did not end the conflict, as the Byzantines launched on and off efforts to reconquer southern Greece (the Principality of Achaea and the Duchy of Athens) and the Aegean islands until the 15th century, while the Latin powers, led by the Angevin Kingdom of Naples, tried to restore the Latin Empire and launched attacks on the Byzantine Empire.

Passage:In 1933, film company Paramount Pictures wanted to re-juvenate and diversify its contract players, and launched a competition known as the "Search for Beauty"; heats took place in nations across the English-speaking world.

Colin Tapley, who would later appear opposite Gray in the TV series Mark Saber, was the New Zealand male winner. In total, there were 30 finalists worldwide, who were screen-tested over six weeks at the end of 1933. Of the 30, bit player contracts were awarded to 10, and Tidbury was selected as the overall male winner with a bonus of US$1,000, with which he bought a car. The overall female winner was Scottish actress Gwenllian Gill, who later followed Tidbury to Britain and became engaged to him; however, their engagement was broken off during the Second World War.
