Pretzel Vendor: The new license fee for operating a pretzel stand outside the art museum is prohibitively expensive Charging typical prices. I would need to sell an average of 25 pretzels per hour to break even. At my stand outside City Hall, with about as many passers-by as at the art museum, I average only 15 per hour. So I could not break even running a stand outside the art museum, much less turn a profit. Which of the following, if true, most seriously weakens the pretzel vendor's argument?

【选项】The pretzel vendor does not sell anything other than pretzels.
