Quiz 13 spanned the periodic table, the tarmac and a wildlife haven off the African coast. Three keepers from a busy week.
What is the lightest element on the periodic table?
Hydrogen, element number one. A single proton and a single electron, nothing more. It is also the most abundant element in the universe, powering every star in the sky, which is a big resume for something so small.
Which airline has a flying kangaroo logo?
Qantas. The flying kangaroo has been on the tail since the 1940s, and the name itself is an acronym: Queensland and Northern Territory Aerial Services. Once you know, you can never unsee the missing U.
Which island nation is famous for its unique wildlife?
Take a look at the map above. It is Madagascar, off Africa's south-east coast. Because it split from the mainland so long ago, most of its wildlife, lemurs included, exists nowhere else on Earth.
That was Quiz 13: the universe's smallest building block, a kangaroo with wings and an island evolution forgot to standardise.
