List two pieces of evidence that Rockefeller used to convince readers to support his arguments about rebates.

While I don't have specific evidence or documents from Rockefeller's arguments, I can provide general strategies and types of evidence that individuals like John D. Rockefeller might have used to convince readers to support their arguments about rebates:

1. Economic Efficiency: Rockefeller could have argued that rebates contributed to economic efficiency by allowing for more competitive pricing. He might have asserted that rebates encouraged efficient business practices, lower costs, and ultimately resulted in more affordable products for consumers.

2. Market Competition: Rockefeller might have emphasized that rebates were a legitimate aspect of market competition. He could have argued that businesses offering rebates were engaging in fair competition, attracting more customers, and fostering innovation within the industry.

It's important to note that Rockefeller, as a powerful industrialist, faced criticism and scrutiny for his business practices, including the use of rebates. The arguments in support of rebates would likely have been framed in a way that highlighted their positive impact on the economy and market dynamics.
