A group of indigenous protesters got a heroes welcome this week in La Paz, Bolivia.
Thousands of people lined the streets to greet them.
The protesters marched for two months from their home in the Amazon.
They're angry at President Evo Morales, and his support for a project to build a highway through their territory.
That territory is within a protected area of the Amazon rainforest.
This national park straddles the Bolivian states of Cochabamba and Beni.
So, your Geo Quiz question is: what's the park's name?
The answer is the Isiboro Sécure National Park and Indigenous Territory (TIPNIS). Anchor Lisa Mullins gets details from the BBC's Mattia Cabitsa in La Paz.
