Quiz 21 went from the fridge to the periodic table to the west coast of South America. These three held up best.
What is the main ingredient in hummus?
Chickpeas, blended with tahini, lemon and garlic. The dip has been eaten across the Middle East for centuries and has now conquered every Australian fridge shelf and school lunchbox.
Why is the chemical symbol for gold Au?
It comes from aurum, the Latin word for gold. A lot of the odd chemical symbols make sense the moment you go back to Latin: iron is Fe for ferrum, and lead is Pb for plumbum, which is also where plumbers got their name.
Which country is famously long and skinny?
Take a look at the outline above. It is Chile, stretching more than 4,000 kilometres down South America's west coast while averaging only about 180 kilometres wide. On a map it looks like someone dragged a country by its corner.
That was Quiz 21: a chickpea empire, some Latin homework and the world's longest skinny country. Geography really does have a sense of humour.
