Final answer:
The statement lacks clarity for a definitive true or false answer regarding ancient Chinese civilizations using mountains for prediction. It is also noted that comparative advantage does not solely stem from natural elements, but can arise from varied sources including technology and skilled labor.
Step-by-step explanation:
The statement in question appears to suggest that ancient Chinese civilizations used natural sources such as mountains for prediction. However, the statement is incomplete and lacks clarity on what kind of prediction is being referred to. Ancient Chinese civilizations were known for using various methods for predictions and divinations, but if the context is about predicting natural events like floods, the ancient Chinese did observe natural signs, but they also developed sophisticated systems like the Dujiangyan irrigation system to manage the water flow and mitigate the risk of floods from the rivers originating in the mountains. Therefore, true or false cannot be determined without more context. Additionally, the Yangtze and Yellow rivers played a significant role in the development of these civilizations due to their dynamic and at times, difficult to control behaviors.
For the Self-Check Question about the source of comparative advantage: Comparative advantage does not necessarily have to be from natural elements such as climate and mineral deposits. While natural elements can contribute to comparative advantage, it can also stem from factors like technology, skilled labor force, and innovative business practices.
