Answer:
The correct answer is: D- observing the orientation of the crescent moon relative to the horizon.
Explanation:
In ancient times, there was hardly any sign of advanced technology which could be used to predict the weather. For this reason, people in Central Africa had their own ways to know how the weather would be like in the coming days. They did so by observing the orientation of the crescent moon relative to the horizon. For example, if the crescent moon held its points upwards, able to contain waiter, it meant dry spells. Some people are still able to predict the weather using such techniques, however, many prefer relying on technology.
