Consider the following pairs: Country - Animal found in its natural habitat: 1. Brazil - Indri; 2. Indonesia - Elk; 3. Madagascar - Bonobo. How many of the pairs given above are correctly matched?

None of the pairs is correctly matched. Indri is a large lemur endemic to Madagascar, not Brazil. Elk (Cervus canadensis) is found in North America and East Asia (including parts of Russia and Mongolia), not in Indonesia. Bonobos are great apes endemic to the Democratic Republic of the Congo, not Madagascar. Therefore, all three pairings are incorrect.
