Passage Summary: A group of people got sick from bad seafood at a restaurant, but when officials checked, most customers that day weren't exposed to the bacteria; despite this, the officials still blame the restaurant's food.

Reasoning: N/A.

Analysis: We have a classic mystery here: how can the restaurant be the source if most diners didn't encounter the bacteria? To resolve this, we need a piece of information that explains why only a small group was affected while the rest were safe. Perhaps the bacteria was limited to a specific dish or a single batch of ingredients that only the sick individuals consumed. Look for an answer that isolates the exposure to just those who fell ill.
