In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[Q]: Passage: The film opens with an English schoolteacher, Gwen Mayfield, packing up her belongings at a mission school in colonial Africa. The local witch doctors have led a rebellion, and they reach the school before she is able to escape—the shaman wearing a body mask. Gwen screams, and the scene dissolves to the opening credits.
The next scene is back home in England, where Gwen meets with the apparently Reverend Alan Bax for a job interview. We discover that Gwen suffered a nervous breakdown from whatever she experienced at the hand of the rebels when the school was attacked. Alan is impressed by Gwen and hires her to be the new head teacher at the small private school he and his sister, well-known journalist Stephanie Bax, run for the local children in the village of Heddaby.
Upon moving into the teacher's cottage, Gwen asks her maid, Valerie Creek, where she might find the rectory. Valerie is confused—she knows there is no rectory—until Gwen explains she would like to thank Mr. Bax. "Oh, you mean the Baxes' house!" she says, and shows her the way after tea.
At the house, Gwen meets Stephanie and mentions she tried to look for the church on the way but couldn't find it. Stephanie explains there isn't any church, and no "Reverend Alan Bax"—but that the pretence is completely harmless. Alan shows Gwen the old church, now a ruin, as he walks her home. He confesses to her that he is not really a priest—"I wanted to enter the Church, but I failed." He notes that he does not try to persuade anyone or officiate, but sometimes wears the priestly collar "for security." Gwen tries to find out more about why the old church was left a ruin but Alan mysteriously turns silent and seems to be unable to move, so she says good night and leaves him to his thoughts. 
Question: What is the full name of the person who wears a priestly collar for security?
[A]: Alan Bax.


[Q]: Passage: Slint formed in 1987 in Louisville, Kentucky, from the remnants of the punk rock band Squirrel Bait; the founding members included Brian McMahan (guitar, vocals), David Pajo (guitar), Britt Walford (drums) and Ethan Buckler (bass guitar). The band's debut album, the Steve Albini-produced Tweez, was released on the group's self-owned label Jennifer Hartman Records and Tapes. The album's sound has been described as a combination of "scratchy guitars, thumping bass lines and hard hitting drums". Buckler promptly left the band out of dissatisfaction with Albini's production, and was replaced with Todd Brashear. The band's second recording was for the instrumental extended play Slint, which included a new version of "Rhoda" from Tweez. The EP, which would not be released until 1994, was a departure from Tweez's sound and reflected the band's new musical direction.After the band ended its brief tour in support of Tweez, most of its members attended college. Around this time McMahan and Walford began writing together for the band's next record, creating six new songs which the band practiced throughout the summer of 1990. Slint entered River North Records in August 1990 to record Spiderland. At that time there were no vocals or lyrics prepared for the album, so the band wrote them while in the studio. The album's producer, Brian Paulson, was known for his "live" recording style in the studio, with minimal takes. Paulson recalled "It was weird while I was doing [Spiderland] because I remember sitting there, and I just knew there was something about it. I've never heard anything like this. I'm really digging this but it's really fucking weird."The recording sessions for Spiderland are reputed to have been difficult for the members of the band and were, according to AllMusic, "intense, traumatic and one more piece of evidence supporting the theory that band members had to be periodically institutionalized during the completion of the album." Rumors circulated that at least one member of Slint had been checked into a psychiatric hospital. Walford later addressed these stories in an article in Select by saying, "[We were] definitely trying to be serious about things, pretty intense, which made recording the album kinda stressful." The recording was completed in four days. 
Question: What is the full name of the person that Todd Brashear replaced?
[A]: Ethan Buckler.


[Q]: Passage: By the late 1950s, Covent Garden was gradually abandoning its policy of productions in the vernacular; such singers as Maria Callas would not relearn their roles in English. This made it easier for Tucker to point up the difference between the two London opera companies. While Covent Garden engaged international stars, Sadler's Wells focused on young British and Commonwealth performers. Colin Davis was appointed musical director in succession to Gibson in 1961. The repertoire continued to mix familiar and unfamiliar operas. Novelties in Davis's time included Pizzetti's Murder in the Cathedral, Stravinsky's Oedipus rex, Richard Rodney Bennett's The Mines of Sulphur and more Janáček. Sadler's Wells's traditional policy of giving all operas in English continued, with only two exceptions: Oedipus rex, which was sung in Latin, and Monteverdi's L'Orfeo, sung in Italian, for reasons not clear to the press. In January 1962, the company gave its first Gilbert and Sullivan opera, Iolanthe, on the day on which the Savoy operas came out of copyright and the D'Oyly Carte monopoly ended.  The production was well received (it was successfully revived for many seasons until 1978) and was followed by a production of The Mikado in May of the same year.The Islington theatre was by now clearly too small to allow the company to achieve any further growth. A study conducted for the Arts Council reported that in the late 1960s the two Sadler's Wells companies comprised 278 salaried performers and 62 guest singers. The company had experience of playing in a large West End theatre, such as its 1958 sell-out production of The Merry Widow that had transferred to the 2,351-seat London Coliseum for a summer season. Ten years later, the lease of the Coliseum became available.  Stephen Arlen, who had succeeded Tucker as managing director, was the primary advocate for moving the company. After intense negotiations and fund-raising, a ten-year lease was signed in 1968.  One of the company's last productions at the Islington theatre was Wagner's The Mastersingers, conducted by Goodall in 1968, which 40 years later was described by Gramophone magazine as "legendary". The company left Sadler's Wells with a revival of the work with which it had re-opened the theatre in 1945, Peter Grimes. Its last performance at the Rosebery Avenue theatre was on 15 June 1968. 
Question: What production was successfully revived until 1978?
[A]:
Iolanthe.
