Question: How many teams did the manager of Shrewsbury Town in 1961 manage? Passage:Originally a winger, Baker joined Plymouth Argyle as a teenager in the early 1950s. He made his first team debut in October 1954, but appeared sporadically over the next three years, as he developed his game playing for the club's reserve team in the Plymouth & District, Devon Wednesday, and Football Combination Leagues. He became a first team regular in 1958, and played an important part in the club's Third Division title campaign a year later. After that success, Baker sustained a knee injury which eventually brought his career at Home Park to an end. He scored 17 goals in all competitions for the club and made 83 appearances. He joined Shrewsbury Town in 1961, who were under the management of Arthur Rowley. He played in the match where Rowley broke Dixie Dean's record for most goals scored in the Football League. After 5 goals in 52 appearances, Baker returned to South Wales in 1962 to play for Barry Town, where he finished his career playing in the Southern League.

Question: How long had the Algerian war been going on when Kopanski was 14? Passage:In 1962, when only 14, he was fascinated by the success of the Arab national and anti-colonial forces that defeated the French colonial armies in the Algerian War, gaining independence for their country. When attending a military college in Kętrzyn (Ger. Rastenburg) in 1966-1969, he actively opposed the Polish communist regime during the 1968 Polish political crisis, and as a result was expelled from the Officer School, and became a political prisoner for the first time. He continued his studies at the University of Silesia in Katowice, and after graduation was employed there as a lecturer,adiunct and researcher. In 1980-81, when Poland was swept by a wave of anti-communist strikes, and around ten million joined the anti-communist Solidarity trade union, Kopański co-founded a branch of this broad grassroots social movement at the University of Silesia.

Question: In what year did Haskell established his own brand of composite material? Passage:Haskell invented a formula for a waterproof glue in 1913. The glue was made from blood-album. From this glue he made a material of "plies" of crossed grain layers of wood, that is known today as plywood. Haskell named this composite material after himself with the brand name Haskelite. He worked out the mechanics of being able to mold and shape this plywood into three dimensions. From this plywood he made a canoe that was molded from one piece of plywood. The canoe plywood was shaped by hydraulic presses as an innovation devised by Haskell. The unusually designed canoe of no skeleton framework or ribs was given the brand name Arex ("king of the water") and made out of the Haskell Manufacturing Company building on N. Rowe Street in Ludington, Michigan. It later became better known just as the Haskell canoe. Haskell formed the Haskell Manufacturing Company in 1916 to make boats and canoes. He incorporated it with $100,000 in 1917. The Haskell Boat Company made 600 Haskell canoes in the first year.
