question 6 of 20
which of these is a factor in the u.s. need to find alternative energy sources?

a. the problems of the car industry

b. problems with interstate commerce

c. worries about overdependence on nuclear power

d. political instability abroad

Explanation:

The U.S. relies on foreign oil from regions with political instability (e.g., Middle East). This instability can disrupt oil supplies, so finding alternative energy reduces reliance on such unstable sources. Option A (car industry problems) is not a direct energy - source - driving factor. Option B (interstate commerce problems) is unrelated to energy sourcing. Option C: The U.S. isn't overly dependent on nuclear power as a primary driver for alternative energy; fossil fuel dependence and foreign political instability are more key.

Answer:

D. Political instability abroad
