Trading with Crete helped the Egyptians develop astronomy, mathematics, and engineering.
Explanation:
The trade relations between the Egyptians and Minoans (the settlers of Crete) began around 4,600 years ago.
Along with precious goods like ivory, gold, and copper, the Minoans also shared the primary knowledge about the disciplines that they had gained initial expertise in.
The Egyptians further developed the disciplines of knowledge by themselves and gained significant expertise themselves.
Because the Egyptians had the resources and the manpower to bring that knowledge into practicality, the technologies used by them became popular eventually.
