Beyond the answers - interesting background to this quiz

A detective story shaped by real trains

Agatha Christie’s Murder on the Orient Express first appeared in 1934. The novel was inspired partly by the long-distance luxury train service that connected Istanbul with western Europe, and partly by real events, including a train stuck in snow and a famous kidnapping case. The Belgian detective Hercule Poirot, already known from earlier Christie books, became one of the most recognisable figures in crime fiction.

When four musicians changed American television

The Beatles’ first appearance on The Ed Sullivan Show on 9 February 1964 is often described as a turning point in American pop culture. An enormous television audience tuned in, and the performance helped launch the so-called British Invasion. The date is frequently used to mark the moment rock and roll entered a new era of mass media attention in the United States.

The long history behind a modern name

Persia was the name used in the West for centuries to describe the country now officially known as Iran. The name Iran has older roots, but the government requested in the 1930s that other countries use it in official communication. The shift did not erase Persian identity, and the Persian language, literature and cultural traditions remain central to the region today.

A river that crosses borders

The Zambezi is one of Africa’s major rivers, flowing through several countries in southern Africa, including Mozambique. It is best known for Victoria Falls and for large hydroelectric dams such as Kariba and Cahora Bassa. Because it crosses national boundaries, the river has long been important for transport, fishing, energy and regional cooperation.
