Beyond the answers - interesting background to this quiz

A currency with a confusing name

Thailand's currency is the baht, often informally spelled "bath" by visitors, which is exactly why the quiz spells it that way. The baht has a long history in the region and is subdivided into 100 satang. If you ever travel there, expect coins for the small change and notes for almost everything else.

The state that printed its own money

Before Vermont joined the United States in 1791, it existed as an independent republic for fourteen years. It had its own constitution, its own postal service and even its own coinage. That brief nationhood still shapes how Vermonters talk about their state today.

Geysers and the thin line between hot and cold

Iceland's geysers are so central to its identity that one of them, Geysir, gave the phenomenon its name. Geothermal activity powers much of the country's heating and electricity. It is a reminder that living on a volcanic island comes with both risks and remarkable natural advantages.

Noble gases and the meaning of "inert"

Xenon belongs to the noble gases, a group that also includes helium, neon and argon. They were once called inert gases because they rarely react with other elements. Xenon is used in high-intensity lamps and even as an anesthetic in some medical settings.

A phrase that outlived its story

"You know nothing, Jon Snow" is spoken by Ygritte, a wildling in Game of Thrones. The line became one of the show's most quoted moments and turned into a meme long before the series ended. It works because it is both affectionate and cutting, which is a hard balance to strike.
