Question: Children in Need 2013 was the first broadcast from the production facility on what road in Hertfordshire?
Context: Elstree Studios on Shenley Road, Borehamwood, Hertfordshire is a British film and television production facility operated by Elstree Film Studios Limited.  One of several facilities historically referred to as Elstree Studios, the Shenley Road studio site opened in 1925. Camp Ravenna Joint Military Training Center, formerly known as the Ravenna Training and Logistics Site and the Ravenna Army Ammunition Plant (RVAAP) and commonly known as the Ravenna Arsenal, is an Ohio Army National Guard military base located between Ravenna and Newton Falls and adjacent to the village of Windham in the U.S. state of Ohio.  Before its present status as a training facility for the Ohio National Guard, Camp Ravenna was a military ammunition production facility for the United States Army.  As an arsenal, the facility was at peak operation during World War II and would serve as an ammunitions plant in various roles until 1992.  Camp Ravenna remains an important part of the history and geography of Portage County, Ohio.  The facility occupies portions of Freedom, Windham, Charlestown, and Paris townships in Portage County, along with part of Braceville Township in Trumbull County. Martinizing Dry Cleaning is a dry cleaning franchise founded in 1949.  Martin Franchises, Inc., the parent company, is the largest dry cleaning franchise in the United States, with over 450 franchised stores worldwide.  The family-owned company is based in Loveland, Ohio.  The concept of One Hour Martinizing was pioneered by a New York chemist named Henry Martin in 1949.  At the time, dry cleaning was done with flammable solvents, so the plants were located remotely from the storefronts.  A customer would drop off their cleaning "in town", the garments would travel to the production facility to be cleaned and pressed, then they would return to the store several days later for pickup.  By using a non-flammable solvent, the use of which was discovered by Martin, dry cleaning plants could now be located much more conveniently, and the process could be carried out in a much more timely manner.  The use of this non-flammable solvent was adopted throughout the industry and revolutionized the business in that facilities could better serve their customers and provide much faster turn-around on the orders, if need be.  Operationally this has been termed "on-site cleaning" (as opposed to the "remote" cleaning of the past). Children in Need 2013 is a campaign held in the United Kingdom to raise money for the charity Children in Need.  2013 marks the 33rd anniversary of the appeal which culminated in a live broadcast on BBC One and BBC Two on the evening of Friday 15 November until the early hours of Saturday 16 November.  The broadcast was hosted by Sir Terry Wogan, with Tess Daly, Fearne Cotton, Zoë Ball and Nick Grimshaw as co-hosts.  The show was broadcast from the BBC in Elstree but also includes regular regional opt-outs.  The 2013 appeal marked the first Children in Need broadcast from BBC Elstree Centre after the closing down of the show's previous home Television Centre.  Its new studio, adjacent to the set of "EastEnders" enabled the show to include live segments and performances from the fictional Albert Square including star interviews in The Queen Victoria Pub hosted by cast member Shane Richie.
