Mackinnon is known for her role in the Baywatch spin-off series Baywatch: Hawaii, where she played the role of 'Allie Reese' opposite David Hasselhoff. She appeared as a regular during the show's first season. MacKinnon is best known for her role as 'Stevie Hall' (later 'Hall-Ryan') in the Logie Award-winning Australian television series McLeod's Daughters, where she appeared at the end of season three through the final season in 2009.

 Passage 2:Casualty is a British medical drama television series that premiered on 6 September 1986 on BBC One. The series was created by Jeremy Brock and Paul Unwin. It is set in the fictional Holby City Hospital, in the equally fictitious city of Holby, and features occasional crossovers of characters and plots with spin-off show Holby City. Casualty follows the professional and personal lives of the doctors, nurses, paramedics, hospital management and patients at Holby General. It features an ensemble cast of regular characters, and began with 10 main characters in its first series, all but two – Charlie Fairhead (played by Derek Thompson) and Lisa "Duffy" Duffin (played by Cathy Shipton) – have since left the show. Many main characters have been written in and out of the series since. In addition, Casualty features guest stars each week, as well as recurring guests that take part in story arcs that span a portion of a series or multiple series.
 Passage 3:Anna Kraus, Op. 30 is a radio opera in one act by composer Franz Reizenstein. The work uses an English language libretto by Christopher Hassall to tell the tragic tale of a German woman who is forced to leave her country due to oppression from the Nazi regime, as the Nazis did not like her political views. The opera was commissioned by the British Broadcasting Corporation following the popular success of Reizenstein's 1951 cantata Voices of Night. The opera premiered on 25 July 1952 on BBC Third Programme with conductor Norman Del Mar leading the BBC Symphony Orchestra and singers Victoria Sladen (as Anna) and Lloyd Strauss-Smith (as Pavel). It was submitted by the BBC later that year for the Prix Italia. Critical reaction to the work was mixed. The New Statesman described the work as "engaging" and a "worthwhile experiment". The Annual Register wrote that the opera "suffered from the composer's emotion being too closely engaged in the sufferings of the heroine, a refugee from political oppression".

Example Input: Question: Of the two offices of Stewards, which was formed first? Passage 1:Amaseia was captured by the Roman Lucullus in 70 BC from Armenia and was quickly made a free city and administrative center of his new province of Bithynia and Pontus by Pompey. By this time, Amaseia was a thriving city, the home of thinkers, writers and poets, and one of them, Strabo, left a full description of Amaseia as it was between 60 BC and 19 AD. Around 2 or 3 BC, it was incorporated into the Roman province of Galatia, in the district of Pontus Galaticus. Around the year 112, the emperor Trajan designated it a part of the province of Cappadocia. Later in the 2nd century it gained the titles 'metropolis' and 'first city'. After the division of the Roman Empire by emperor Diocletian the city became part of the East Roman Empire (the Byzantine Empire). At this time it had a predominantly Greek-speaking population.
 Passage 2:The first known appointment to the position was that of Denzil Onslow in 1686 or 1694. He was deprived of his office in 1711 when the Junto Whigs were crushed. In 1715, the office was granted to Denzil's great-nephew Hon. Thomas Onslow. While it provided an emolument for him, the principal purpose of the appointment was to force Thomas to vacate his seat as Member of Parliament for Guildford, under the terms of the Place Act 1707. By removing him from the House of Commons, he could now stand in the by-election for Surrey, which had been vacated when his father Richard was made a Teller of the Exchequer. (Richard was about to be made a peer, hence his failure to stand in the by-election himself.) Two years later, when Thomas succeeded to his father's barony, Denzil Onslow again received the office for the same reason, vacating his seat at Guildford to successfully contest Surrey. This presaged the use of other offices of profit under the Crown as a means of resignation from the British House of Commons, which became formalised in the offices of Steward of the Chiltern Hundreds and Steward of Northstead.
 Passage 3:Vallow then went on to Sony to produce their first primetime series, Dilbert, with Larry Charles, which ran on UPN for two seasons. She then took over as producer for season three of Family Guy before its brief cancellation. In 2004, Vallow created and produced the animation sequences in the critically acclaimed and award-winning documentary In the Realms of the Unreal directed by Jessica Yu. She produced the MTV series 3 South, the pilot for Comedy Central’s Drawn Together and the presentations for Fox’s American Dad! and an untitled Phil Hendrie pilot, before Fox made the decision to bring back Family Guy for an unprecedented 35 episode order. In order to accommodate producing both Family Guy and American Dad! simultaneously, she built a standalone animation studio for 20th Television and assembled a 200+ person team. She also produced the Fox presentations Two Dreadful Children and Bordertown. Nominated for five Emmys, Vallow was at one time responsible for three half-hours of programming on Sunday nights: Family Guy, American Dad!, and The Cleveland Show.

Example Input: Question: How many years did the Sacrifice pay-per-view-event happen? Passage 1:The Impact World Championship is a professional wrestling world championship owned by the promotion Impact Wrestling, formerly Total Nonstop Action Wrestling (TNA). From June 2002 to May 2007, TNA used the NWA World Heavyweight Championship as their primary championship due to an agreement with the National Wrestling Alliance (NWA). On May 13, 2007, the NWA abruptly ended the arrangement and retrieved control of the NWA World Heavyweight Championship. On the same night, TNA were set to host their annual Sacrifice pay-per-view event, in which the NWA World Heavyweight Championship was to be defended by then-champion Christian Cage against Kurt Angle and Sting in a three-way match. Angle won the match and on the following episode of TNA's television program Impact! on May 17, was declared the new TNA World Heavyweight Champion. He was stripped of the championship later in the program, with Management Director Jim Cornette citing a problematic finish to the title match. The ownership of the championship was decided on June 17, 2007 at TNA's Slammiversary event in a King of the Mountain match involving Angle and Cage along with A.J. Styles, Chris Harris and Samoa Joe, which Angle won.
 Passage 2:In 1916, the 10th Field Artillery was activated for federal service in World War I, and Danford commanded the regiment during its initial training at Tobyhanna Army Depot. From February to July 1917, Danford was assigned as assistant professor of military science at Yale University, and served as the mustering officer for members of the Connecticut National Guard as they entered federal service. While at Yale, Danford co-authored Notes on Training Field Artillery Details, a practical manual for teaching field artillery tactics and techniques. It quickly became the Army's standard reference work for training field artillery soldiers, and went through numerous printings during and after World War I. In July 1917, Danford served as mustering officer for members of the Pennsylvania National Guard, after which he traveled to Fort Sill, where he served as an artillery instructor. Originally slated to join the 42nd Division, in August, he was instead assigned to the 302nd Field Artillery, a unit of the 76th Division. He trained with the regiment at Camp Devens, Massachusetts, after which he was assigned to Plattsburgh Barracks, New York as senior instructor of field artillery for the Army's second wartime Officers' Training Camp. He was promoted to major in August, and temporary lieutenant colonel on the same day.
 Passage 3:"Midnight Sun" is a song recorded by the Romanian female singer Elena Gheorghe. The song was recorded in summer 2010 and premiered on November 15, 2010, on Gheorghe's official YouTube channel. It was released under Cat Music exclusively in Romania. The song has more house influences than the previous number-one hit "Disco Romancing". It was sent to the mainstream radio stations in late November and it is promoted as the second single taken from Gheorghe's album entitled Disco Romancing. Lyrically, the song describes the shiver a millionaire wannabe guy gets when he sees Elena dancing. The song had its official radio premiere on the Romanian National Day, at radio ZU, though it premiered on Kiss FM a week earlier. Elena performed "Midnight Sun" live, on December 31, during a New Year special show, held by Pro TV. The music video was already shot in Bucharest and it was released via YouTube on May 13, 2011. The video features many special effects as well as the track listing for Gheorghe's upcoming album. The song peaked at number-one the Radio Top 50 and charted within the top ten in two other Romanian charts. In the official Romanian Top 100 it peaked at number-ten, thus making it Elena's fifth song to enter the top ten in Romania, after "Soarele meu", "Vocea ta", "The Balkan Girls" and "Disco Romancing". The song was performed at many dates throughout Romania.
