Beyond the answers - interesting background to this quiz

The slowest journey around the sun

Neptune takes roughly 165 Earth years to complete a single orbit, which is why it holds the record for the longest year among the planets in our solar system. It was discovered in 1846, meaning it has completed only about one full orbit since then. Uranus, by contrast, finishes its own lap in about 84 Earth years.

A feisty island survivor

The Tasmanian devil is the largest carnivorous marsupial alive today, known for its powerful bite and its loud, screeching calls. It is now found only on the island of Tasmania, after disappearing from mainland Australia. Since the 1990s, a contagious facial cancer has severely reduced its numbers, and conservation efforts remain ongoing.

An island in the Ionian

Zakynthos sits in the Ionian Sea off the western coast of Greece, and it is one of the country's most visited islands. Its most famous beach, Navagio, is framed by limestone cliffs and a rusting shipwreck that has become a favourite subject for photographers. The island is also a major nesting ground for loggerhead sea turtles.

A name older than the country itself

Until 1935, the country we now call Iran was known internationally as Persia, a name rooted in the ancient Greek term for the region. In that year, the government asked foreign countries to use the name Iran, which had long been used within the country itself. "Iran" derives from an old word meaning "land of the Aryans".

A dish with imperial roots

Peking roast duck is one of China's best-known culinary exports, celebrated for its crisp, lacquered skin and tender meat. The dish is traditionally associated with Beijing and has been prepared there for centuries, with records pointing to imperial kitchens. It is typically served with thin pancakes, spring onions and a sweet bean or plum sauce.
