The statement that best reinforces Feldman's claim that people are mostly honest is: "Feldman's payment system was largely successful." This follows from the text, in which Feldman's trade scheme is reported, through which he distributed bread rolls using an honor system that consisted of handing some rolls and a basket of cash to the company's refreshment room; and would return later before lunch to collect money and leftovers. Through this system the assertion that people are mostly honest is demonstrated
Based on the excerpt, the statement that best strengthens Feldman's claim that people are mostly honest is the second one: "Feldman's payment system was largely successful".
This fact is the key of Feldman's project because he developed a business and a payment method that could have not worked, but it did. The payment system, in this case the cash basket, showed him that he could trust people. Actually, the key of his success was the confident relationship he developed with his clients. This confidence in the costumer's good behaviour in the payment method was the evidence he needed to believe in people's good intentions and honesty.
