Question: In what city is the school that Porter attended from 1969-1973? Passage:Claire Porter was born in New Britain, Connecticut, where, as a child, she was a star athlete and danced in a local studio. After she earned her BA in Mathematics from the College of New Rochelle in New York, she became a computer programmer for G.E. Analytical Engineering in Schenectady, New York. Porter returned to her dancing roots after witnessing a performance by Maria Tallchief. She then attended Sonoma State University in California from 1969-1973. At Sonoma State, she studied dance, taught Family Dance, Exercise, and Children’s Dance, and directed a dance company of 12 members. Porter eventually moved from California to Ohio to study dance at Ohio State University. It was there that Porter discovered Laban Movement Analysis and began exploring gestures, acting, writing, and voice. She later received her certification for Laban Movement Analysis at the Laban/Bartenieff Institute of Movement Studies NYC. She earned her MA in Dance from Ohio State and has continued the exploration of gestural movement as a teacher, choreographer and performer.

Question: What teams had the newly hired head coach and offensive co-ordinator for the Argonauts worked for previously? Passage:However, with the 1982 season came the hiring of Bob O'Billovich as head coach and Mouse Davis as offensive co-ordinator. Davis implemented the run and shoot offense, and the Argos enjoyed a turnaround, going 9–6–1 that year; Condredge Holloway was the CFL's most outstanding player. The team ultimately fell short in their quest for a Grey Cup, losing 32–16 in a driving rainstorm to the mighty Edmonton Eskimos (in what would be the last of their five consecutive Grey Cup titles) in the final in front of a disappointed crowd at Exhibition Stadium. The 1983 season finally brought the championship home. The Argos finished 12–4 and Terry Greer set a CFL record with 2,003 receiving yards. Joe Barnes and Condredge Holloway were a potent duo at quarterback. The Double Blue returned to the Grey Cup, this time facing the BC Lions at BC Place Stadium in Vancouver. Despite the hostile crowd, Toronto defeated BC 18–17 to win their first Grey Cup since 1952. The Argos were generally competitive for the remainder of the 1980s, thanks in large part to talented players such as Gill "The Thrill" Fenerty and Darrell K. Smith, but a return to the glory of 1983 proved elusive (outside of an appearance in the 1987 Grey Cup game, in which they lost in the last minute to the Edmonton Eskimos 38–36).

Question: How many years were there between the completion of Westminster Abbey and the completion of the Cathedral of the Immaculate Conception? Passage:The construction of the cathedral was approved in 1894 by the Ministry of Internal Affairs under Tsarist Russia. Groundbreaking was in 1899; construction work began in 1901 and was completed ten years later. Three-aisled and built from red brick, the cathedral is based on a design by architect Tomasz Bohdanowicz-Dworzecki. The style was influenced by Westminster Abbey and Milan Cathedral. With the help of funds from Catholic parishes in Russia and its neighbouring states, the church was consecrated as a chapel for Moscow's Polish parish in 1911. In the aftermath of the Russian Revolution in 1917, the Provisional Government was overthrown by the Bolsheviks and Russia eventually became part of the Soviet Union in 1922. Because the promotion of state atheism was a part of Marxist–Leninist ideology, the government ordered many churches closed; the cathedral was closed in 1938. During World War II, it was threatened with demolition, and was used after the war for civil purposes, as a warehouse and then a hostel. Following the fall of communism in 1991, it returned to being a church in 1996. In 2002 it was elevated to the status of cathedral. Following an extensive and costly programme of reconstruction and refurbishment, the cathedral was reconsecrated in 2005.
