question 4 of 25
what is one reason for the united states to develop alternative - energy sources?

a. unsteady politics in foreign countries

b. lack of progress in research on car engines

c. the dangers of nuclear power plants

d. complex trade laws between the states

Explanation:

The U.S. relies on foreign countries (e.g., Middle East) for fossil fuels. Unsteady politics in these regions can disrupt oil supply, so developing alternative energy reduces dependence on unstable foreign energy sources. Option B is incorrect as car engine research has advanced. Option C: Nuclear power is not the main driver for alternative energy (focus is on fossil fuel issues). Option D: State - to - state trade laws don't relate to national alternative energy development.

Answer:

A. Unsteady politics in foreign countries
