 Passage 2:As a backbencher in Ralph Klein's Progressive Conservative caucus, Knight moved a number of government bills. The first was 2003's Electric Utilities Act, which made some changes to the government's deregulation of the province's electricity market. Much of the debate around the bill was about whether the government's deregulation had worked well to date. The bill was passed on a party line vote, with Knight's fellow Progressive Conservatives voting unanimously in favour and the opposition Liberals and New Democrats voting unanimously against. Knight also sponsored the Securities Amendment Acts, separate bills with the same name from different years, 2005 and 2006. The first of these was designed to harmonize the securities regulation with that of other provinces. It was supported by Liberals Rick Miller and Bill Bonko, who considered it a step in the right direction. New Democrats gave it a mixed reception, with Ray Martin agreeing that it did make some improvements, but with his colleague David Eggen trying to kill it on third reading, saying that what was needed was a supra-provincial securities regulator. The 2006 edition of the Securities Amendment Act implemented further harmonization, and passed with little debate. The Securities Transfer Act of the same year consolidated and harmonized the province's rules for transferring securities, and passed with all-party support.
 Passage 3:On January 13, UFC revealed this event was originally intended to take place at Arena da Baixada (a much larger venue) in Curitiba, Brazil, and feature a UFC Heavyweight Championship rematch between champion Fabrício Werdum and former two-time champion Cain Velasquez, with former UFC Middleweight Champion Anderson Silva in the co-main event slot, possibly against Michael Bisping. Due to a series of injuries, the company moved the heavyweight bout to a separate event scheduled for February 6, which at that time was . This change made the March 5 event a smaller draw, which led to the transition to the smaller venue in Rio de Janeiro. To maintain local interest, the company then considered booking the main event as a rematch between two Brazilian fighters, Silva and former UFC Light Heavyweight Champion Vitor Belfort. Belfort declined the bout, as he wished to wait for the result of the middleweight title fight at UFC 194. This final fall-through is what prompted the cancellation of the event in Brazil and relocation to Las Vegas. On January 27, it was revealed the Werdum-Velasquez bout (which had been moved to "UFC 196" scheduled for February 6, 2016) was cancelled entirely. This forced that event to alter into a "UFC Fight Night" card, and the originally scheduled "UFC 197" event was renamed UFC 196.

 Passage 3:"Promise This" is an up-tempo dance-pop song written by American songwriter Priscilla Hamilton, British music producer Wayne Wilkins, who was responsible for Cole's debut single "Fight for This Love", and Christopher Jackson.

The basic chord progression of the song is Cm, Cm, Cm, Cm, E♭, B♭, F, Cm, E♭, B♭ and F. The song sees Cole singing some of the lyrics in French, referencing the children's song "Alouette". It was recorded in Santa Monica, California, and "finds her contemplating mortality with a cheerful morbidity, asking for prayers over a brutal march beat." Tabloids suggested that the lyrics were based upon her divorce from footballer Ashley Cole, and how her dancer friend Derek Hough nursed her to health while she was suffering from malaria. The Daily Star had also noted Cole's apparent affection in the song by her use of the French word alouette, meaning "skylark".
