Question: Who was the coach of the team that Brentford lost against in League Cup first round in the 2012-13 season? Passage 1:Nantz joined CBS Sports in 1985, initially working as a studio host for the network's college football and basketball coverage, and as an on-course reporter for PGA Tour golf, as well as calling NFL games on Westwood One (from 1988 to 1990, when he was moved to television, Nantz called Sunday Night Football games for what was then called CBS Radio Sports). Nantz has anchored CBS' coverage of the Masters Tournament since 1989. He teamed with Billy Packer to call the NCAA Final Four men's basketball finals from 1991 until 2008. From 2008 to 2013, Clark Kellogg had been his analyst. From 2010 to 2013, Nantz and Kellogg were joined during the Final Four by Steve Kerr of TNT Sports. From 2013 to 2014, Greg Anthony partnered with Nantz. Following Anthony's suspension, Bill Raftery and Grant Hill were selected to replace him and are Nantz's new partners. Leading up to the Final Four, Nantz typically covers the games of the team awarded the overall #1 seed.
Passage 2:Why Do These Kids Love School? is a documentary film directed by filmmaker, Dorothy Fadiman, which examines an independent school, Peninsula School, followed by visits to eight public schools around the country (pre-school through high school) all of which have innovative programs. What emerges is the value of implementing humane values and programs that value creative thinking, self-directed learning, and first-hand experience more than memorization of facts. The schools in the film are Peninsula School, Graham and Parks School in Cambridge, Massachusetts, Central Park East Secondary School in New York City (now a high school since 2005), Clara Barton Open School in Minneapolis, Clement Gregory McDonough City Magnet School in Lowell, Massachusetts, Jefferson County Open School in Lakewood, Colorado, New Orleans Free School (closed after Hurricane Katrina), Central Park East II in New York City, and Davis Alternative Magnet School in Jackson, Mississippi.
Passage 3:Brentford began the season with a disappointing 10 defeat at the hands of Walsall in the League Cup first round and hovered around mid-table in League One before coming into form in late October 2012. Summer forward signing Paul Hayes failed to produce regular goals and was replaced by Huddersfield Town loanee Jimmy Spencer, who in turn was replaced by Marcello Trotta and the Italian would remain with the Bees for the duration of the season on loan from West London rivals Fulham. Inspired by the form of attacking midfielder Harry Forrester, an unbeaten run of 9 wins and four draws in 13 matches between 23 October 2012 and 21 January 2013 firmly established the Bees as challengers for automatic promotion, rising as high as 2nd position in the table. Headway was also made in the FA Cup during the same period, with victories over Boreham Wood, Bradford City and Southend United setting up a fourth round tie versus West London neighbours Chelsea at Griffin Park on 27 January. In a match televised on ITV, Brentford twice took the lead through a quick-reaction Marcello Trotta finish and a Harry Forrester penalty, but the Premier League side ensured a replay when Fernando Torres pulled the score back to 22 with seven minutes remaining. Brentford were comfortably beaten 40 at Stamford Bridge in the replay and the match ended on a sour note when Chelsea defender David Luiz's "sickening" late shoulder charge on Bees midfielder Jake Reeves went unpunished and left Reeves concussed.
