What problem has China tried to solve by building hydropower dams, such as the Three Gorges Dam? A. scarcity of water B. lack of arable land C. production of greenhouse gases D. damage from earthquakes and tsunamis
The problem that China has tried to solve by building hydropower dams, such as the Three Gorges Dam, is C. production of greenhouse gases.
The problem that China has tried to solve by building hydropower dams, such as the Three Gorges Dam, is A. scarcity of water.
To arrive at this answer, we can eliminate options B, C, and D based on their relationship to hydropower dams:
B. Lack of arable land: Hydropower dams do not directly relate to the issue of arable land. They are primarily built to generate electricity by harnessing the power of flowing water.
C. Production of greenhouse gases: Hydropower is a renewable energy source that produces minimal greenhouse gas emissions. Unlike fossil fuel-based power plants, hydropower relies on the natural flow of water, making it a cleaner energy option.
D. Damage from earthquakes and tsunamis: While seismic activity can potentially affect the construction and operation of hydropower dams, it is not the primary motivation for building them. The focus is primarily on energy generation and addressing specific challenges associated with water resources.
Option A remains as the most logical answer: scarcity of water. China, being a populous country with water resource challenges, has built hydropower dams as a way to manage water resources, generate electricity, and potentially mitigate water scarcity issues. The Three Gorges Dam, for example, serves multiple purposes, including flood control, power generation, and improving navigation along the Yangtze River.
