Are the traditional houses in the Middle East all high-rise houses?

The Middle East has a tropical desert climate, which is hot, dry and windy. The walls of houses built in the Middle East are thick for heat insulation, and the windows are small because of the strong light in the Middle East. Small windows effectively block a lot of strong light and prevent the invasion of sandstorms, while light colors are used to reflect strong sunlight. Therefore, most residents in the Middle East have thick walls, small windows and light colors, in order to adapt to the local hot, dry and windy climate. So option d fits the question.

Therefore, choose: d.
