Answer: B)Feldman’s payment system was largely successful.
Step-by-step explanation:
Feldman was earning much more than he did as a research analyst which means that he was earning a lot of money from this business which further means that his payment system was largely successful.
This means that people are mostly honest because his payment system was based on honesty in that he simply left the cash basket there and people could either have not paid or could have taken money from the basket but they didn't(at least not significantly) which could only happen if people were honest.
