Beyond the answers - interesting background to this quiz

An island capital that keeps outgrowing its own name

Jakarta sits on the northwest coast of Java and has been Indonesia's capital since the country declared independence in 1945. It is one of the most populous urban areas on Earth, and the city has struggled for years with severe traffic and sinking ground. That is why Indonesia has been building a new capital, Nusantara, on the island of Borneo.

The poem that gave Italian its shape

Dante Alighieri wrote The Divine Comedy in the early 1300s, and it became a foundation stone of modern Italian. The poem follows the poet through Hell, Purgatory and Paradise, guided first by the Roman poet Virgil and later by Beatrice. Dante wrote in the Tuscan vernacular rather than Latin, a choice that helped shape the literary language of Italy for centuries.

One phrase, many musketeers

"All for one and one for all" is the motto of the musketeers in Alexandre Dumas's 1844 novel. The story centres on d'Artagnan, a young Gascon who joins the king's musketeers, and his friends Athos, Porthos and Aramis. Dumas based the characters on real musketeers from seventeenth-century France, though the adventures are largely his own invention.

Bohemia, a region with many names

Bohemia is a historical region of the Czech Republic, and Czech is the language spoken there. The name comes from the Boii, a Celtic people who once lived in the area. In English, "bohemian" also came to describe an unconventional, artistic way of life, a meaning that grew out of later associations between the region and travelling Romani communities.

Portugal and the line that runs through Greenwich

Greenwich Mean Time takes its name from the Royal Observatory in Greenwich, London, which sits on the prime meridian. Portugal lies close to that same line of longitude, so mainland Portugal keeps time within one hour of GMT. The country spans only a narrow band of the globe, which makes it a neat example of how time zones follow geography rather than politics.
