 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".

[EX Q]: Question: Who was the host of the Olympics where Henry Littlewort won a gold medal? Passage 1:Due to a double election of François Louis, Prince of Conti and the Frederick Augustus I, Elector of Saxony (elected King of Poland as Augustus II) in 1697, the two claimants to the Polish throne had serious troubles with obtaining approval of the nobility for their coronation. The most difficult situation was of Elector of Saxony, who had no support of the primate Michał Stefan Radziejowski and most of the senators holding the custody of the Wawel Castle Crown Treasury. Therefore, expecting obstacles in obtaining the royal insignia, he ordered to prepare replacements before his arrival to Kraków. On the eve of the ceremony, some of the gathered decided to find a way to obtain the original regalia. Two monks Aleksander Wyhowski, prior of Czerwińsk and Mikołaj Wyżycki, prior of the Holy Cross made a hole in the castle's wall and got to the vault from which they stole the crown, scepter, sword and orb. The Dresden regalia become unnecessary, Augustus II the Strong, however, treated them as a private insignia.
 Passage 2:Crystal Palace started their second season in a new division, having gained promotion from the Southern League Division Two the previous season. There were a number of personnel changes this season, with Archie Grant and captain Ted Birnie moving to Chelsea and George Walker going to New Brompton. Palace's hat-trick hero in their FA Cup exploits of last season, Walter Watkins, also moved on to Northampton Town. In their places Palace brought in a number of new faces. Charles Ryan joined from Nunhead, Thomas Wills from Newcastle, Bill Forster from Sheffield United and Bill Ledger from Pryhope Villa. Wilf Innerd was made captain and played in all but one of the club's League and Cup matches. The club struggled to find their feet on the new division, and failed to score in 13 of their matches, finishing the season in 19th position, one place off the bottom. This was enough to ensure safety though, as for this season there was no relegation. Palace again called on a number of amateurs from the local area and beyond, including Henry Littlewort. Littlewort, who made his only appearance for the club this season, would go on to win a gold medal with the British Football team in the 1912 Olympics.

[EX Q]: Question: After Manga Video announced that they planned to start releasing Ranma 1/2 in 1994, when did they actually start releasing it? Passage 1:AUKcon was a one-day anime convention held in London, England, on 19 February 1994. The venue was the Conway Hall (Red Lion Square), and the registration charge was £10. AUKCon was chaired by Helen McCarthy. During the convention, Lawrence Guinness of Manga Video announced that the company had acquired distribution rights for Ranma 1/2 and planned to start releasing it in 1994. Also announced included plans for the series Bio Booster Armor Guyver. One of the guests that attended was Toren Smith, writer of the American Dirty Pair comic and founder of Studio Proteus. The convention was the first UK anime event to provide a fan room with free space for fanzines and fanclubs. It also ran a gaming programme and an art and model show, as well as anime screenings and talks. 
 Passage 2:While still a youth in 265 BC, Fabius was consecrated an augur. It is unknown whether he participated in the First Punic War, fought between the Roman Republic and Carthage from 264 to 241 BC, or what his role might have been. Fabius' political career began in the years following that war. He was probably quaestor in 237 or 236 BC, and curule aedile about 235. During his first consulship, in 233 BC, Fabius was awarded a triumph for his victory over the Ligurians, whom he defeated and drove into the Alps. He was censor in 230, then consul a second time in 228. It is possible that he held the office of dictator for a first time around this time: according to Livy, Fabius's tenure of the dictatorship in 217 was his second term in that office, with Gaius Flaminius as his deputy and magister equitum during the first term: however Plutarch suggests that Flaminius was deputy instead to Marcus Minucius Rufus - presumably Fabius's great political rival of that name, who later served as deputy to Fabius himself (see below). It is of course possible that Flaminius was successively deputy to both, after Minucius's apparently premature deposition following bad augural omens: and also possible that little of note (other than, possibly, holding elections during the absence of consuls) was accomplished during either dictatorship.
 Passage 3:During the Winter 2017 TCA Press Tour, series mainstays Sarah Paulson and Evan Peters were reported to be starring as the leads in the season. In March 2017, Billy on the Street host Billy Eichner was announced to be cast in the series, playing a role in the life of Paulson's character. His character is slated for appearing in "six or seven" episodes. The next month, it was reported that Scream Queens actress Billie Lourd will also star in the seventh installment of the series. In May 2017, Leslie Grossman, who starred in Murphy's series Popular, joined the cast of the series, and Angela Bassett hinted she may return in a recurring role. Despite this, Bassett didn't appear, but she did direct the episode "Drink the Kool-Aid". Later that month, it was confirmed via set pictures that Adina Porter and Cheyenne Jackson were also returning. In June 2017, Murphy confirmed via his Instagram account that Colton Haynes, whom Murphy worked with previously on second season of Scream Queens, was joining the casting for the seventh season. Later that month, set pictures revealed that Alison Pill was joining the cast of the season, seemingly portraying the partner of Sarah Paulson's character. In July 2017, Murphy revealed via his Twitter account that Lena Dunham was joining the season. She is set to play Valerie Solanas, author of the SCUM Manifesto and attempted murder of Andy Warhol, via flashbacks. Murphy also confirmed the returns of Frances Conroy and Mare Winningham. Conroy has appeared in all the seasons except Hotel, while Winningham has appeared in Coven, Freak Show, and Hotel. In August 2017, Murphy confirmed the return of Emma Roberts, who appeared in Coven and Freak Show, while Roanoke actors Chaz Bono and James Morosini also confirmed their returns.
