Which of the following favours the growth of olives in the Mediterranean region of Africa?

The growth of olives in the Mediterranean region of Africa is favoured by cool, wet winters and warm, dry summers. Olives require a specific growing season, and the Mediterranean climate provides the ideal conditions. During the winter months, the temperature is cool, and there is enough rainfall to provide moisture for the trees to grow. In the summer, the temperatures are warm and dry, which allows the olives to ripen and mature. Additionally, the moderately stiff loam or clayey soil found in the Mediterranean region is also suitable for olive growth. High humidity and heavy rainfall are not favourable for olive growth as they can lead to disease and rot. Finally, an abundant supply of skilled labour is important for olive cultivation, but it is not a factor that directly favours the growth of olives.
