The correct answer is false.
It is false that homes in the Nile delta were made out of wood.
There was not enough wood in ancient Egypt. They lived in a desert, where they had palms, not trees. They used to build their homes with bricks and rocks, that could resist even the flooding of the Nile. Egyptians could predict the flooding of the Nile and were prepared because that allowed them to have fertile lands an grow crops.
