I disagree with your answer.

The question is asking why a lot of people chose to live in river valleys.

Please try again.

Oh ok thank you for your help.

Actually, the correct answer is option D. During early civilizations, most cities rose in river valleys because these areas were fertile and supported large populations through agriculture. The availability of water from the rivers made the land fertile, which in turn allowed for the growth of crops and the establishment of successful farming communities.

To get to this answer, you can analyze the provided options and eliminate the incorrect ones. Option A suggests that river valleys provided work to men who built dikes and canals, which may have been true but does not directly address the rise of cities. Option B mentions easy access to travel and trade, which is a factor but not the primary reason for the rise of cities. Option C suggests that city-state government centers were located in river valleys, which may have been true in some cases but does not explain why cities rose in those areas initially.

By process of elimination, option D is the most accurate choice. It highlights the importance of fertile lands in river valleys, which supported the development of agriculture and sustained growing populations.
