Pretzel vendor: The new license fee for operating a pretzel stand outside the art museum is prohibitively expensive. Charging typical prices, a vendor would need to sell an average of 25 pretzels per hour to break even. At my stand outside city hall, I average only 15 per hour. Therefore, I could not break even running a pretzel stand outside the art museum, much less turn a profit.

Which of the following, if true, most strongly supports the pretzel vendor's argument?

【选项】Pretzel vendors who operate stands outside the art museum were making a profit before the imposition of the new license fee.
