Read the following paragraph and select the correct answer from the options.
Passage:
Sea waves can cause serious damage when they hit the land. Even under a clear sky and calm sea, a huge wall of water can suddenly appear—20 or 30 feet high—destroying homes and putting lives at risk.
These waves often form after a strong underwater earthquake. The earthquake creates a shock in the deep ocean, which moves upward and creates a giant swell on the surface. These ocean swells can be up to a mile wide and rise to tens of feet in height.
People didn’t start to address the danger of tsunamis until after World War II. These waves move towards land at very high speeds—hundreds of miles per hour—and hit with great force.
