Read the following passage, then answer the question.John Rockefeller might get his oil cheaper now and then, they said, but he
could not do it often. He might make close contracts for which they had neither the patience nor the stomach. He might have an unusual mechanical and practical genius in his partner. But these things could not explain all. They believed they bought, on the whole, almost as cheaply as he, and they knew they made as good oil and with as great, or nearly as great, economy. He could sell at no better price than they. Where was his advantage
He has no close contracts with shopkeeper in order to sell his product. His oil has low quality which is the main reason for not selling his oil. For making profit, he has to enhance the quality of oil as well as having close contracts with shopkeeper so that the oil will be sold at high price and make more profit. He should have patience and use his brain in order to make good profit and gain advantage from these ideas.
