The correct answers are:
- mild climate;
- many waterways;
- level fertile land;
The farming in the southern parts has been a great success from its beginnings up until the present. This is due to multiple factors, including the mild climate, the abundance of waterways, and the fertile soil.
The climate is very suitable for agriculture, it is relatively warm and humid, with enough precipitation, and the temperatures in winter are not extreme.
Because there's lots of rainfall, there's lots of waterways as well. So apart from the natural irrigation through the rainfall, the farmers had the option to irrigate whenever they wanted by using the rivers and streams.
The fertile land is essential for good farming, and the climate in this region has enabled the formation of good and fertile soil, so the farming was of high quality.
