Doubled Up 'D's Trivia Quiz

Answer: Danube

The waltz in question is 'The Blue Danube', written by Johann Strauss the Younger in 1866 and first performed, in Austria, a year later. It is Opus 314 by Strauss and also known by its German name, 'An der schönen blauen Donau'. It is a famous classical work and became particularly associated with the film '2001: A Space Odyssey' thanks to its inclusion at key points of the soundtrack.

The River Danube flows across Europe from its source in Germany's Black Forest to its mouth on Romania's Black Sea coast. Along its route it flows through four European capital cities, including Belgrade (Serbia), Budapest (Hungary), Bratislava (Slovakia) and Vienna - the capital of Austria, which was the birthplace of Johann Strauss and is shown in the picture clue.

The Dnieper flows through Russia, Belarus and Ukraine; the Dniester can be found in Ukraine and Moldova; and there are various rivers called the Don, but the longest of these flows through Russia.

Answer: Dakota

Dakota Fanning is an American actress whose film career started in 2001 with her appearance in 'I Am Sam' when she was just seven years old. She appeared in three of the five films that were based on Stephenie Meyer's 'Twilight' series of novels about the relationship between a human and a "vegetarian" vampire. Fanning played a vampire named Jane who was part of an elite vampire army and had a special psychic ability to inflict pain on others.

As well as being found in the name of two US states (see the map in the picture clue), the name Dakota also refers to the Native American Dakota people (a subgroup of the Sioux) and to a language spoken by them.

Answer: Dacia

The region once known as Dacia was located in Eastern Europe. It covered an area surrounding the Carpathian mountains, to the west of the Black Sea, and its territory largely corresponded to parts of modern-day Romania, Moldova and Bulgaria. It was home to the Dacian people but was invaded and conquered by Rome in 106 AD, during the rule of the Emperor Trajan. It then became a province of the Roman Empire known as Roman Dacia or Dacia Traiana, as shown by the map in the picture clue.

The car manufacturer called Dacia was founded in Romania in 1966 and became part of the Renault group in 1999. Its models include the Logan (a small family car), the Duster (a compact SUV) and the Sandero (a small city car). The latter was often mocked in the "News" section of the BBC motoring show 'Top Gear'.

Daewoo, Daimler and Daihatsu are all car manufacturers but have no etymological connection to the Roman Empire.

Answer: Daphne

'Scooby-Doo' is a popular animated TV series that first aired in 1969, although the franchise has also expanded into comic books and films. The hero is an anthropomorphic Great Dane who has the ability to talk to his four teenage friends - Daphne, Fred, 'Shaggy' and Velma. Daphne was the ginger-haired girl usually seen wearing a purple dress, who constantly ended up in dangerous situations from which she had to be rescued by the rest of the gang.

The genus of plants known as daphnes (pictured) are shrubs that make popular garden plants thanks to their pleasantly-scented flowers and bright berries. They are evergreens and tend to flower during the winter and early spring.

Answer: Albus Dumbledore

The word 'dumbledore' is an old English term for a bumblebee (if you don't know what one looks like then see the picture clue), derived from 'dumble', meaning slow-moving, and 'dor', meaning an insect.

J.K. Rowling's 'Harry Potter' series of novels and films included several characters from the Dumbledore family, the most prominent of which was Professor Albus Dumbledore, the long-time headmaster of Hogwarts School of Witchcraft and Wizardry. The only other Dumbledore to appear in person was the headmaster's younger brother Aberforth, the barman of the Hog's Head in the wizarding village of Hogsmeade. The first mention of Aberforth related to the fact that he had once been "prosecuted for practising inappropriate charms on a goat". The other members of the family were Percival, Kendra and Ariana Dumbledore (Albus and Aberforth's parents and younger sister).

Answer: Diamond

One of the many editions of the 'Pokémon' series of video games was a 2006 release for the Nintendo DS called 'Pokemon Diamond'. It was part of the fourth generation of 'Pokémon' games produced by Nintendo and introduced over 100 new Pokémons for people to play with. The name "Pokémon" is a contraction of "Pocket Monsters" and the general aim of the game is to collect these small characters and then deploy them in battle against other players.

Diamonds are a form of carbon that is the hardest mineral found on Earth. Thanks to their beauty when polished, cut and set in jewellery (and a noted advertising campaign by the De Beers company that introduced the slogan 'A Diamond Is Forever') they are particularly associated with the tradition of engagement rings. However, the picture clue shows what a diamond looks like before it is polished and cut...this one went on to become the famous Cullinan diamonds.

Answer: Dan Dare

Dan Dare was created by Frank Hampson in 1950 for the launch of the 'Eagle' and featured on the front page of the first edition. The comic book was the brainchild of the Rev. Marcus Morris who wanted to provide children's stories that focused on Christian values. Dan Dare was the pilot of a futuristic spacecraft who travelled the solar system on various missions.

In the Bible, Dan was the fifth son of Jacob by Bilhah, a servant of Rachel, his favourite wife. Each of Jacob's twelve sons were the founder of one of the Tribes of Israel. The Tribe of Dan was allocated territory on the Mediterranean coast that neighboured the Philistines. As implied by the picture clue, the tribe is often associated with the serpent in iconography because of a line from Genesis that states "Let Dan be a serpent by the roadside".

Dick Tracy and Dennis the Menace are also well-known comic book characters. David Haller is the birth name of the superhero Legion from Marvel Comics 'X-Men' series.

Answer: Earl of Dumfries

In 1986, the two F1 drivers who competed for the Lotus team were an up-and-coming Brazilian by the name of Ayrton Senna and a British aristocrat who used the courtesy title of Earl of Dumfries, but preferred to be known - in racing circles at least - as Johnny Dumfries. He spent only that single season in F1, having scored only three points (with a best result of fifth place at the British Grand Prix) in comparison to Senna's 55 points with two race victories.

However, he was part of the team that took victory at the famous 24 Hours of Le Mans sportscar race in 1988. He drove for Jaguar alongside fellow British driver Andy Wallace and a Dutchman named Jan Lammers. He became the 7th Marquess of Bute on the death of his father in 1993. The picture clue shows a satellite image of the Isle of Bute in Scotland, which is home to the family seat, Mount Stuart House.

Answer: Desdemona

Desdemona appeared in 'Othello', one of William Shakespeare's best known and most popular plays. She was the ill-fated wife of the titular character who is also known as the "The Moor of Venice" - hence the picture clue, which shows the 1697 painting 'View of the San Marco Basin' by Gaspar van Wittel. In the play, Othello was influenced into believing Desdemona had been unfaithful to him and subsequently murdered her, making it no surprise that it is classified as one of Shakespeare's tragedies.

All of the moons of Uranus are named after either Shakespearean characters or characters created by the poet Alexander Pope. Desdemona was first discovered by the Voyager 2 space probe in 1986 and is one of the planet's small inner moons; its diameter is only approximately 64 kilometres (40 miles) in length.

The incorrect options all appear in Shakespeare plays. A character named Diana features in 'All's Well That Ends Well', Diomedes appears in 'Antony and Cleopatra' and Dorcas is in 'The Winter's Tale'.

Answer: Dances with Wolves

COWHAND LIVES WEST can be rearranged to form the name of the Kevin Costner film 'Dances with Wolves'. The film is based on a novel by Michael Blake and features Lieutenant John Dunbar, an officer with the Union Army, who was posted to Fort Hays in Kansas during the American Civil War. It tells the story of Dunbar's growing friendship with both the local Sioux people and a wolf named Two Socks.

In total 'Dances with Wolves' won seven Academy Awards, including Best Picture, Best Director (for Kevin Costner), Best Adapted Screenplay (Michael Blake) and Best Original Score (John Barry). Costner was also nominated for the Best Actor Oscar but lost out to Jeremy Irons.
