What percentage of OPEC's oil was being imported into the United States during the late
1970's?
A. 10%
B. 25%
C. 50%

B. 25%

Explanation:

during the 70's the OPEC's import rates were incredibly low. But the oil was selling for a whopping 5$ per barrel which was ten percent higher than before. But as I said above, import rates were low, making it about 25%.

Hopefully this is the correct answer! :)

monarchy doesn’t have to have the hereditary element. there have been elective monarchies in the past where you choose your king-for-life and when he dies elect someone else for the job.
