Answer: a. there was a strong tendency to come from a business-elite background (76%)
Explanation:
Beth Mintz and Peter Freitag analyzed the backgrounds of every cabinet member serving between 1897 and 1973. Not only did they found that 66% of them could be considered as part of the upper class before getting their cabinet jobs, but also that more than 76% of them were connected with prominent corporations, and 90% of them came either from upper class or were linked with those corporations.
