Rivers of the World
From the Nile to the Amazon — the great rivers that shaped where we live.
Which river is traditionally considered the longest in the world?
A flag can pack centuries of history into a few colours and shapes. Ten questions on the banners of the world, each with the story behind it.
A national flag is a compressed argument about who a people are: their history, their values, and sometimes their disputes, all packed into a few colours and shapes. This quiz asks you to match flags to countries and to read the meaning behind the designs, from the symbols that repeat across a region to the ones unique to a single nation. Each answer is explained, so a flag you get wrong becomes a small piece of a country's story. It is a surprisingly deep way to travel the world, one banner at a time.
Every question in this quiz is listed below with its correct answer and the reasoning behind it. Play first if you would rather not see the answers — or read through as a study sheet.

Why: Canada adopted its red-and-white maple leaf flag in 1965, replacing earlier designs based on the British ensign.
Answer: A. A red circle for the sun
Why: Japan's flag, the Nisshōki, shows a red disc representing the sun on a white field; the country's name means "origin of the sun".
Answer: D. Nepal
Why: Nepal's flag is two stacked triangular pennants, representing the Himalayas — the world's only non-rectangular national flag.
Answer: C. Germany
Why: Germany's flag has three horizontal bands of black, red and gold. Belgium shares the same colours but arranges them in vertical stripes.
Answer: B. Australia
Why: Australia's flag features the Union Jack, the seven-pointed Commonwealth Star, and the five stars of the Southern Cross constellation.
Answer: A. Switzerland
Why: Switzerland's flag is a white cross on red, and it is one of only two square national flags — the other belongs to Vatican City.
Answer: D. The Ashoka Chakra
Why: India's tricolour of saffron, white and green carries a navy blue 24-spoke wheel, the Ashoka Chakra, at its centre.
Answer: C. 13
Why: The 50 stars represent the current states and the 13 stripes stand for the original colonies that declared independence in 1776.
Answer: A. Finland
Why: The Nordic cross, with its vertical bar shifted toward the hoist, appears on all the Nordic flags, including Finland's blue cross on white.
Answer: A. Libya
Why: For those years Libya's flag was a single solid green field — the only national flag ever to have no design or other colour at all.
