What percentage of north american adults may be functioning below their potential due to prolonged exposure to stress?
a. 35-40 percent
b. 45-50 percent
c. 15-20 percent
d. 50-60 percent

More than half of the population of North America suffers or may be suffering from prolonged exposure to stress, creditably because of World War II and the Cold War that gave fear and stress of a global catastrophe. The best answer is D, but if this was conducted as some type of census, it is possible for it to be B, but it isn't too likely because they said "may be". Options A and C are definitely not the answer to this question. If you liked this answer, please give a Brainiest medal.
