Answer:
True
Explanation:
The model of the universe developed by Nicolas Copernicus gave better predictions than the model of Ptolemy. The model of Ptolemy had prevailed for centuries, and it placed the Earth at the center of the universe. However, Copernicus accurately established that the sun was located at the center of the solar system. Moreover, Copernicus also established that the Earth is only one of many planets, that the Sun is stationary and that the Earth moves in three different ways (daily, annual, and annual tilting), among other astronomical principles.

The history of North Africa is intertwined inseparably with European history (Roman Empire, the Greek Empire etc.), Persian history, Arab history and the history of the Ottoman Empire.
North Africa belongs to the Mediterranean world, northern coastal regions particularly (the food is typically Mediterrenean food). North Africa belongs to the Arab World. Arab culture is very strong and dominant. There is also a major influence of the Turkish culture.
