Passage Summary: If coffee bean prices go up, the shop must raise its own prices, which leads to two options—selling other stuff or losing customers—both of which will hurt the shop's bottom line.

Reasoning: Rising bean costs lead to higher prices, which result in either new products or fewer sales; however, both of those outcomes lead to lower profits.

Analysis: This is a formal logic puzzle where all roads lead to the same destination. If the initial condition (rising bean prices) occurs, it triggers a chain of events where every possible branch results in a decrease in overall profitability. Specifically, if the shop sells noncoffee products, profit drops; if it loses sales, profit also drops because the text states profit only stays stable if sales do not decrease. Therefore, you should look for an answer that concludes that an increase in the price of coffee beans will inevitably lead to a decrease in the shop's profitability.
