II. Read the passage and choose the best answers.
With all of these incredible underwater structures already existing worldwide, a natural question emerges: Why can't we build underwater cities?
The short answer is that we can. We have the materials, technologies, and construction techniques to support human cities under the sea. However, underwater cities, at least right now, have a cost that makes them unreasonable, which is why we only tend to see underwater structures pop up at expensive resorts around the world.
Nevertheless, architects and engineers have already begun considering plans for elaborate underground cities in various forms. From the Japanese Shimizu Corporation, one such plan imagines an undersea spiral spanning from the ocean's surface down to the seafloor. This structure could house 5,000 inhabitants, generate power, and withstand natural disasters like earthquakes and tsunamis. However, the project costs at least $26 billion and currently only exists as a fantasy.
Still, human innovation has made it possible to build underwater structures in ways that seemed impossible just a short time ago. It may not be long before floating cities, submerged cities, or cities on the seafloor become a reality.
