Q: Question: How long did Blake Nill coach for the Calgary Dinos? Passage 1:Recording sessions for the album began in 2003. The album was broken down into three parts. The first part of the record (credited as "Cassidy") was more pop and radio friendly, with records such as "Get No Better" and the R. Kelly assisted lead single "Hotel". The second part of the record (credited as "The Problem") was targeted directly towards his fans, who began to support him following his appearances on various mixtapes with songs such as "Blood pressure" and "The Problem". The third and final part of the record (credited to "B. Reese") was more introspective and aimed towards his fans who have supported him since his early days of his rap career with "Husslin" and "Real talk". The album's lead single, "Hotel" (which is a reference to the song "Housewife", from Dr. Dre's album 2001) featuring American R&B singer-songwriter R. Kelly, was created during recording sessions at Kelly's Chicago studio "The Chocolate Factory". R. Kelly also appears on the official remix to "Hotel", with guest vocals from American rapper Trina. The song was a hit and reached the top ten on the US Billboard Hot 100, as of February 2004. The song was also nominated for a Vibe Award for the "Coolest Collabo" in 2004. The album's second single, "Get No Better", which features guest appearances from then label-mate R&B singer Mashonda, as well as vocals from label owner and mentor Swizz Beatz. while the song did not do as well on the singles charts as "Hotel", it did reach number 82 on the US Billboard Hot 100. It was followed up by a music video, which features Vida Guerra as the lead female. songs "Take It" and "Make You Scream Pt.2" were also recorded during the Split Personality sessions but were eventually scrapped and later used only as official promotional singles from the album.
 Passage 2:During the following off-season in 2015, UBC Athletics would draw the Dinos head coach, Blake Nill away from the Calgary Dinos in what was the most high profile coaching change that year. Nill's impact was immediate as he was able to recruit quarterback Michael O'Connor, who was the ranked the sixth best quarterback by ESPN among the 2014 recruiting class. The Thunderbirds achieved a turnaround in Nill's debut season at the UBC helm to finish the 2015 regular season with a 6–2 record, placing second in the CWUAA standings. During the ensuing post-season drive of three straight single-elimination playoff games on the road, UBC upset the heavily favoured Calgary Dinos in the Hardy Cup game at Calgary; then defeated the St. Francis Xavier X-Men to earn its historical first Uteck Bowl victory at Antigonish, to advance to the national title game. In the 51st Vanier Cup championship, the Thunderbirds narrowly defeated the defending CIS champion Montreal Carabins, by scoring the game's last possession field goal to end the fourth quarter. The victory was UBC's fourth Vanier Cup overall, tying the Calgary Dinos for the all-time record among CWUAA member universities.
 Passage 3:The original Enfield Station in Windmill Hill opened on 1 April 1871 as the terminus for the Great Northern Railway branch line from Alexandra Palace. By 1887, 37 trains a day left Enfield, mainly for King's Cross, but also to Broad Street and until 1907, to Woolwich and Victoria. The station building was a two-storey twin-gabled house, similar in style to the single-storey building at Palmers Green. It was sited lengthways across the end of the track. The single island platform was covered by a wide canopy for much of its length. Enfield Station had been intended to bring prosperous middle-class commuters to the area. A journalist visiting the station in 1885, saw a sign advertising cheap workmen's tickets for trains scheduled to arrive in London before 8 am, only to find that the timetable showed that there were no trains that met that criterion. The old Enfield Station closed to passengers in 1910 and was replaced by the present station, but remained in use as a goods depot until 1974. The surviving buildings were demolished and replaced in the 2000s with housing along a new street, Gladbeck Way.
