Adric died when the freighter struck Earth, the impact that wiped out the dinosaurs; the episode ended with uniquely silent credits in his memory.
Q 06Who co-wrote the 1979 Doctor Who serial 'City of Death' under the pseudonym David Agnew?
Douglas Adams
Douglas Adams, then the show's script editor, rewrote another writer's story over a single weekend with his producer's help, so a BBC house pseudonym took the credit.
Q 07Which Doctor Who companion, played by Matt Lucas, debuted in the 2015 Christmas special?
Nardole
Nardole was beheaded in his first episode and his head fitted to a robot body; the Doctor later rebuilt him, and he stayed on to help guard a mysterious vault.
Q 08Which Fourth Doctor companion was a warrior from the 'savage' Sevateem tribe?
Leela

Vicki, a 25th-century orphan, stayed behind in Troy in 'The Myth Makers' (1965) after falling for the warrior Troilus; King Priam renamed her Cressida.
Q 10Which companion of the Second Doctor, a young astrophysicist with a photographic memory, had her memories wiped by the Time Lords?
Zoe Heriot
Zoe Heriot travelled with the Second Doctor; after 'The War Games' the Time Lords returned her and Jamie to their own times and erased their memories, except of first meeting the Doctor.
Q 11Which accessory does the Eleventh Doctor repeatedly insist is 'cool'?
Bow ties
Bow ties were the actor's own idea: he asked to try one at a costume fitting, the production team groaned, and then they saw it on him and were won over.
Q 12What does the acronym TARDIS stand for?
Time and Relative Dimension in Space
Time and Relative Dimension in Space is the wording of the first episode; in 1965 an actor said 'Dimensions' in place of the scripted singular, and both versions have been heard since.
Q 13A Dalek's manipulator arm famously resembles which household object?
A sink plunger
Q 21What process lets a dying Time Lord change physical appearance and personality?

Q 22Kaled scientist Davros built his people into armoured travel machines on which planet?
Skaro
Skaro is where, in 'Genesis of the Daleks', Davros's creatures refuse to take orders from anyone who is not one of them and turn their guns on their own creator.

The Invisible Enemy
'The Invisible Enemy' introduced K-9 as the pet of Professor Marius, who had built the robot to replace the real dog he had to leave behind on Earth, and who gives him to the Doctor at the end.
A sink plunger: a real one served as the arm on the original props, and although later Daleks have tried claws and even a blowtorch, the plunger keeps coming back.

Tom Baker
Tom Baker was hauling bricks on a building site when he won the part, because acting work had dried up.

Ninth: the revival kept the classic count, following the Eighth Doctor of the 1996 TV film; a later story squeezed a hidden 'War Doctor' between them without renumbering anyone.
Q 17In which episode did the terrifying Weeping Angels first appear?
Blink
'Blink' was that year's 'Doctor-lite' episode, made while the leads filmed another story, so guest star Carey Mulligan carries it as Sally Sparrow.

Sonic Screwdriver
The Sonic Screwdriver was destroyed on screen in 1982 because its producer felt it got the Doctor out of trouble too easily; it stayed away until the 1996 TV film.

Q 26With which two classic-era incarnations did Sarah Jane Smith primarily travel as a companion?
