I want to know the answer to the following question:
What is the largest dam ever built in the world?
All the background I'm provided with is that "The plan is hailed by some as China's efforts to shift towards alternative energy sources and to further develop its industrial and commercial bases, but others have criticised it for its potentially harmful effects, such as massive resettlement of residents in the reservoir areas, loss of archeological sites, and ecological damages.". Is that enough to answer the question?
Answer: no
