Today's Geo Quiz takes us to Burma or Myanmar.
Reports from that country say police have arrested an American who illegally entered the compound of the pro-democracy leader, Aung San Suu Kyi.
The Nobel Prize winner and opposition leader has been under house arrest for over a decade in Yangon.
That's the former Rangoon -- and also the country's former capital.
Burmese authorities say this American intruder was caught after he swam across a lake near Suu Kyi's home.
So -- naturally we want you to name this scenic lake in the middle of Yangon.
And you need to think fast.
