Sales manager: Last year the total number of meals sold in our company' s restaurants was much higher than it was the year before. Obviously consumers find our meals desirable. Accountant: If you look at individual restaurants, however, you find that the number of meals sold actually decreased substantially at every one of our restaurants that was in operation both last year and the year before. The desirability of our meals to consumers has clearly decreased, given that this group of restaurants -- the only ones for which we have sales figures that permit a comparison between last year and the year before -- demonstrates a trend toward fewer sales. If the sales figures cited by the accountant and the sales manager are both accurate, which one of the following must be true? ["The market share captured by the company's restaurants fell last year.", "The prices of the company's meals have changed over the past two years.", 'The company opened at least one new restaurant in the last two years.', "The quality of the company's meals has not improved over the past two years."]
