Beyond the answers - interesting background to this quiz

A country with more than one name

The quiz's first question touches on something Indians themselves debate: the country is officially known as both India and Bharat, and the constitution opens with the phrase "India, that is Bharat". "Bharat" comes from Sanskrit and is tied to ancient epic tradition, while "India" derives from the Indus river. In recent years, the balance between the two names has become a lively political topic in the country.

Two naturalists, one big idea

Charles Darwin is the name most people attach to the theory of evolution, but Alfred Russel Wallace reached similar conclusions independently while working in Southeast Asia. The two men presented their ideas together to a scientific society in London in 1858, and Darwin's book "On the Origin of Species" followed a year later. Wallace's contribution is a reminder that big scientific breakthroughs rarely happen in complete isolation.

Who the Cro-Magnon people really were

"Cro-Magnon" is not a species name but a label taken from a rock shelter in southwestern France where early modern human remains were found in 1868. These people lived in Europe tens of thousands of years ago and are classified as European early modern humans. They left behind remarkable cave art, including the famous paintings at Lascaux.

The Guggenheim and its spiral

New York's Guggenheim Museum is as famous for its building as for its art. Designed by Frank Lloyd Wright, it opened in 1959 and is shaped like a giant white spiral, with visitors walking gradually downward past the works. The design was controversial at first, but it is now one of the most recognisable museum interiors in the world.

Why magnets prefer some materials

A magnet's pull is strongest on iron, cobalt and nickel, which is why "metal" is the safe answer in the quiz. Not all metals respond equally, though - aluminium and copper are barely affected, and stainless steel depends on its exact composition. Plastic and water, meanwhile, are essentially unaffected by an ordinary fridge magnet.
