Question: Was the league where Thomas won an award in 1985 founded before the one where he played junior hockey? Passage:Thomas went undrafted after his junior career but signed as a Free Agent with the Toronto Maple Leafs. He began his NHL career in the 1984–85 season. Thomas was born in Stockport, England but was raised in Markham, Ontario, Canada where he attended Markham District High School. As he often coasted in school on his hockey skills, he once had a teacher tell him to "smarten up, Steve; hockey can only take you so far". He played junior hockey for the Toronto Marlboros of the OHL (he was the last original Toronto Marlboro to make it to the Maple Leafs of the NHL). Prior to playing in the NHL, Thomas won the Dudley "Red" Garrett Memorial Award in 1985 as the top rookie in the American Hockey League, while playing for the St. Catharines Saints.

Question: Who was the coach of the team Tony Craig played against in his first game in the first division? Passage:Born in Greenwich, London, Craig came through the youth ranks at Millwall. Adept as a central defender or a left back, he received his maiden call into the first team squad for a First Division league match against Bradford City on 5 April 2003 and was an unused substitute during the 1–0 win. Craig made his professional debut with a starting appearance in a 3–3 draw with Nottingham Forest on 26 April 2003 and lasted 67 minutes before being substituted for Robbie Ryan. He started in the final game of the 2002–03 season at home to Coventry City and scored the first senior goal of his career in the 2–0 win, with the opener on 51 minutes. Craig began the 2003–04 season as a virtual ever-present, making 10 appearances, but he dropped out of the squad entirely in October 2003. He was again out of favour with manager Dennis Wise during the 2004–05 season and had to wait until 19 February 2005 for his first appearance, which came with a start in a 1–0 defeat to Stoke City and he finished the campaign with 10 appearances.

Question: How long did Caratacus live after he was defeated in battle and fled to the Brigantes? Passage:The general outline of the Roman conquest of Britain during the 1st century AD is recorded by historical sources; for the involvement of specific forts historians depend on archaeological excavations. This part of Britain was occupied by a tribe known as the Cornovii. In AD 46–47 the Roman Army led by governor Aulus Plautius had probably occupied the lands to the south of the River Trent. Late in 47 the new governor of Britain, Ostorius Scapula, began a campaign against the tribes of the western mountains (modern Wales). Caratacus, their leader, was defeated in battle in AD 50 and fled to the Brigantes who occupied the Pennines. Their queen, Cartimandua, came to terms with the Romans and handed Caratacus over to them. Ostorius died and was replaced by Aulus Gallus who brought the Welsh borders under control but did not move further north or west. It was at about this time that the fort at Strutt's Park was built. It probably lay not far south of the border between Roman territory and that held by the Brigantes, who were now an allied or subject kingdom.
