Question: How long had the TWR Jaguar World Sportscar Championship team been in existence when Elio de Angelis joined it? Passage 1:"The Ivory Goddess" is a short story by American writers L. Sprague de Camp and Lin Carter, featuring the fictional sword and sorcery hero Conan the Barbarian created by Robert E. Howard. According to Morgan Holmes, citing de Camp friend Loay Hall, Carter did none of the writing, and the story was written by de Camp in collaboration with his wife Catherine Crook de Camp. The story was first published by Bantam Books in the paperback anthology Conan the Swordsman in August 1978. Later paperback editions of the collection were issued by Ace Books (1987 and 1991). The first hardcover edition was published by Tor Books in 2002. The book has also been translated into Italian. It was later gathered together with Conan the Liberator and Conan and the Spider God into the omnibus collection Sagas of Conan (Tor Books, 2004). The story has been translated into Italian.
 Passage 2:Another recurring character in the series was Little Quacker the duckling, who was later adapted into the Hanna-Barbera character Yakky Doodle. He appears in Little Quacker (1950), Just Ducky (1953), Downhearted Duckling (1954), Southbound Duckling (1955), That's My Mommy (also 1955), Happy Go Ducky (1958), and The Vanishing Duck (1958). Quacker talks a lot compared to Tom and Jerry. His voice is a 'duck voice' not dissimilar to Disney's Donald Duck. In many shorts, he is the only character who speaks. He is very trusting, even trusting Tom in many situations in which Tom wishes to eat him. He is a friend of Jerry, but unlike Jerry harbors no hard feelings towards Tom. He appeared in The Tom and Jerry Show episode "The Lost Duckling" (1975). He also got his own series of shorts on The Yogi Bear Show (renamed Yakky Doodle) after guesting in several Hanna-Barbera TV shows. Quacker was then used as a template for the 'Hard Luck Duck' character starring in the titular character's short from the What a Cartoon! series. His What a Cartoon! counterpart Hard Luck Duck was voiced by Russi Taylor.
 Passage 3:Italian driver Elio de Angelis who had joined Brabham after six years with Lotus, was the first driver to die in a works Brabham when he was killed in an accident while testing at the Circuit Paul Ricard in France. The car survived the accident relatively intact and de Angelis had only minor injuries. However, there were very few track marshals at the circuit and he was trapped in the car and killed by oxygen deprivation due to a fire before they arrived, prompting a review of testing safety, with changes including more marshals as well as medical staff and a required medical evacuation helicopter. Sadly de Angelis would die from smoke inhalation 29 hours after the crash at the hospital in Marseille where he had been taken. In the Belgian Grand Prix following the death of de Angelis, Brabham only entered one car for Patrese. From the next race in Canada, British driver Derek Warwick joined the team. According to team boss Bernie Ecclestone, Warwick, a former factory Renault driver who had been driving for the TWR Jaguar World Sportscar Championship team in 1986 after having missed out on a seat at Lotus, was reportedly the only top level driver without a current F1 drive who did not contact him in the days following de Angelis' death to ask about the drive.
