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. Ttherefore, 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? ['Fewer people passing the art museum than passing city hall are to buy pretzels.', 'People who buy pretzels at pretzel stands are most likely to do so during the hours at which the art museum is open to the visitors.', 'The number of pretzel stands outside the art museum is no greater than the number of pretzel stands now outside city hall.', 'Pretzel vendors who operate stands outside the art museum were making a profit before the imposition of the new license fee.']
