Passage Summary: A business writer argues that a watch company shouldn't make more watches even though people want them, because the only reason people want them is that they are hard to find.

Conclusion: The manufacturer of Corinne wristwatches should not increase supply to meet the current high demand.

Reasoning: The high demand is driven by the public's perception of scarcity; if the supply were increased, the watches would no longer be seen as exclusive, causing the demand to vanish.

Analysis: The claim mentioned in the stem serves as the main conclusion of the argument. Every other sentence in the stimulus provides a psychological or economic explanation to support the idea that increasing supply would be counterproductive. When identifying the role of a statement, look for whether it is the 'final point' the author wants you to accept or merely a stepping stone to get there.
