[EX Q]: Passage: In 1975 his orchestral Fourth Sonata (written 197475) won the Scottish National Orchestra's Ian Whyte Award. Subsequent orchestral works include the widely performed Night Music (1976), Sonata No. 5: Landscape (197781), and a First Cello Concerto, commissioned by the BBC for the 1984 Proms: these last two have been recorded by Unicorn-Kanchana. In 1989 Cortege was given its first performance by the Orchestra of the Royal Opera House under Bernard Haitink, and Quatrain by the London Symphony Orchestra and Michael Tilson Thomas. This was the first of a series of LSO commissions, followed by Machines and Dreams for their 1991 Childhood Festival, Memorial in 1993 with Mstislav Rostropovich as conductor, and a Second Cello Concerto for Rostropovich in 1996. In 1990 he made a setting of three comic poems by Wendy Cope, Strugnell's Haiku. Matthews was Associate Composer with the LSO from 1992 until 1999. The orchestral version of Hidden Variables was a joint commission for the LSO and the New World Symphony Orchestra, who gave the American premiere in Miami under Michael Tilson Thomas in 1992; in the same year the Cleveland Orchestra gave the American premiere of Machines and Dreams. Collins Classics released a CD of Matthews' LSO commissions in 1996 to celebrate his 50th birthday.

[EX Q]: Passage: Chibnall suggested including a "bonkers" gang of characters picked from around time and space. He felt that Doctor Who could have "collisions of characters that no other show in the world can do", and that it was about finding a "disparate" group of characters who would "bounce" off each other. Nefertiti's decision not to return to her own time fits in with the historical record, as the date and cause of her death are unknown. Chibnall asked to introduce Rory's father, as Amy and Rory would be leaving in four episodes and Rory's family life had not been explored yet. Mark Williams who played Rory's father previously appeared in the Fifth Doctor audio adventure The Eternal Summer. Rupert Graves, who played an Edwardian hunter in this episode, previously worked with Moffat on the BBC series Sherlock. David Bradley's character, Solomon, was modelled on a "well-known nightclub owner with long hair". Chibnall described him as "half businessman, half Somali pirate". Bradley and Williams had previously worked together on the Harry Potter film franchise. Bradley was later cast as the First Doctor William Hartnell for the 50th anniversary documentary drama An Adventure in Space and Time. Comedy duo Mitchell and Webb provided the voices of Solomon's two robots; executive producer Caroline Skinner called the casting choice "perfect". Richard Hope, who played the Silurian Bleytal, previously appeared as Malohkeh in the episodes "The Hungry Earth", "Cold Blood" and "The Wedding of River Song".

[EX A]: Answer: 2013

[EX Q]: Passage: Beginning in 1986, Warner Bros. moved into regular television animation production. Warners' television division was established by WB Animation President Jean MacCurdy, who brought in producer Tom Ruegger and much of his staff from Hanna-Barbera Productions' A Pup Named Scooby-Doo series (19881991). A studio for the television unit was set up in the office tower of the Imperial Bank Building adjacent to the Sherman Oaks Galleria northwest of Los Angeles. Darrell Van Citters, who used to work at Disney, would work on the newer Bugs Bunny shorts, before leaving to form Renegade Animation in 1992. The first Warner Bros. original animated TV series Tiny Toon Adventures (19901995) was produced in conjunction with Amblin Entertainment, and featured young cartoon characters based upon specific Looney Tunes stars, and was a success. Later Amblin/Warner Bros. television shows, including Animaniacs (19931998), its spin-off Pinky and the Brain (19951998), and Freakazoid! (19951997) followed in continuing the Looney Tunes tradition of cartoon humor.
