The correct ways in which geography has affected settlement patterns in North Africa are:
- Areas with a good climate for farming attract higher populations.
- Densely populated areas are found near water sources or areas with regular precipitation.
- Settlement is concentrated along the Mediterranean coast and Nile River Valley.
The other options regarding rain forests and tropical wet climate zones are not applicable to North Africa, as the region is largely characterized by arid and semi-arid climates rather than dense rainforests.
