Passage Summary: An executive decided not to sell herbal supplements because they don't work, assuming that if they aren't effective, they won't make any money.

Conclusion: Marketing herbal tinctures would not result in the intended goal of increasing profits.

Reasoning: The executive's staff and medical publications indicate that herbal tinctures are not medically effective.

Analysis: The executive is operating under a specific principle: that a product's medical efficacy is a requirement for its commercial success. While this sounds noble, it's a bit naive in the business world where plenty of useless products make a fortune. To match the reasoning to a generalization, look for a statement that links the failure of a product to perform its stated function with a failure to achieve a business goal like profit. The logic assumes that consumers only buy things that actually work.
