Beyond the answers - interesting background to this quiz

A Hollywood star who chose to stay behind the camera

Robert Redford is best known as an actor, but his 1980 directorial debut, "Ordinary People", won him an Academy Award for Best Director. The film, adapted from Judith Guest's novel, follows a grieving family struggling to reconnect after a tragedy. Redford went on to found the Sundance Institute, which helped turn independent filmmaking into a major force in American cinema.

The eye's coloured ring

The iris is the ring of tissue around the pupil, and it is the part of the eye that can appear hazel - a mix of brown, green and gold. Eye colour comes from the amount and distribution of melanin in the iris, and no two irises are patterned exactly alike. Hazel eyes are relatively uncommon and can seem to shift colour depending on the light.

Egypt's crossroads position

Egypt shares borders with Libya to the west, Sudan to the south and, in the northeast, the Gaza Strip and Israel. The country sits at the junction of Africa and the Middle East, and the Suez Canal - opened in 1869 - made it one of the world's most important maritime shortcuts. That position has shaped Egyptian trade, politics and culture for centuries.

A ballet that caused a riot

Igor Stravinsky composed "The Firebird" for Sergei Diaghilev's Ballets Russes, and its 1910 premiere in Paris made the young composer famous almost overnight. Three years later, Stravinsky's "The Rite of Spring" provoked a famously chaotic first night, with fights breaking out in the audience. Together, the two works helped redefine what orchestral music could sound like.

Anatolia, the land bridge

Anatolia is an early name for the region that makes up most of modern Turkey, and it has long served as a bridge between Europe and Asia. Civilisations from the Hittites to the Byzantines and Ottomans left their mark there, and the peninsula remains one of the most archaeologically rich places on earth. The name is still used today for the Asian part of Turkey.
