the river valley civilizations had similar geography, trade, and goods across regions.

Explanation:

River - valley civilizations like Mesopotamia, Egypt, Indus - Valley, and China engaged in inter - regional trade. They also had pastoral groups as part of their economies. Isolated territories were not a common economic characteristic as they traded. The Silk Road emerged much later than the river - valley civilizations. Sailboat travel was not a universal feature for all river - valley civilizations. Similar geography is not an economic characteristic. Inter - regional trade and pastoral groups are key economic elements.

Answer:

The river valley civilizations all had interregional trade, pastoral groups, and isolated territories.
