| :---: | :---: | :---: | :---: | :---: | :---: |
| San-Mateo | 18.3 | 120.2 | Souvenir industry | 117 | r. Rio-Blanco |
| Coralio | 8.4 | 30.3 | Shoe export | 5 | r. Rio-Blanco |
| Alasan | 12.0 | 45.9 | Banana cultivation | 349 | Wells and boreholes |
| Alforan | 9.4 | 19.6 | Income from chess tournaments | 593 | r. Rio-Blanco |
| Solitas | 4.1 | 8.4 | No income | 232 | r. Rio-Blanco |
Solution. Alasan is the only city not located on the banks of the Rio Blanco, but gets its water from wells. Therefore, Alasan has the number 2.

The lower a city is along the river, the lower its elevation above sea level. Only the "Elevation above sea level" value is required from all available statistics.

Answer: 1 - Alforan, 2 - Alasan, 3 - Solitas, 4 - San-Mateo, 5 - Coralio.
