Passage Summary: A manager thinks business is booming because total sales are up, but an accountant points out that every old location is actually losing customers, suggesting the food is losing its touch.

Conclusion: The overall consumer appeal of the company's meals has declined.

Reasoning: Sales dropped significantly at every single restaurant that was open during both the previous and current years.

Analysis: The accountant is falling into a classic trap by looking only at a subset of data—the 'old' restaurants—and ignoring the impact of new ones. If the company opened several new locations that are absolutely swamped with customers, total desirability could be skyrocketing even if older locations are flagging. To weaken this, we should look for an answer that suggests the sales drop at old locations is due to something other than the food's appeal, such as the company cannibalizing its own market by opening new spots nearby. It is a classic case of 'the parts don't always represent the whole,' especially when the company's footprint is changing.
