Elag for Review Scientists today are studying tidal power as an alternative energy source for generating electricity
Some scientists conclude that tidal power is a good alternative source of energy because it uses a natural process, does not rely on fossil fuels, and does not
release greenhouse gases. These scientists recommend building tidal power
plants around the United States in
locations with high tidal power potential.
Other scientists conclude that tidal power is not a good alternative energy source because tidal power plants can negatively impact the surrounding ecosystem by
killing marine animals, restricting fish migration, reducing the natural flow of water, and causing silt buildup in waterways. These scientists recommend not
building tidal power plants in U. S. waterways.
Both conclusions are based on valid data and scientific reasoning. How can both conclusions be valid?
ОА. The two groups of scientists believe different theories about the process of generating electricity
ОВ.
The two groups of scientists are looking at different specific aspects of the same scientific problem.
The two groups of scientists collect and analyze data about all types of possible alternative energy sources.
OD. The two groups of scientists are on opposite sides of the debate on whether the United States needs to find clean alternative energy sources.
