Passage Summary: Two car executives are debating whether an ad is deceptive: one says it's a lie because their new models have the feature mentioned, while the other says it's fair because many older models without the feature are still being sold.

Reasoning: N/A

Analysis: The core of the disagreement is the definition of 'deceptive' in advertising. The Zahler executive believes that if the newest model has a feature, saying they 'lack' it is a lie. The Graham executive believes that as long as there are still many cars on the lot without the feature, the claim remains valid. You are looking for a principle that Graham would embrace—likely one that allows for generalizations based on current dealer inventory—which Zahler would find unacceptable. It's a classic case of 'technically true' versus 'the whole truth.'
