Passage Summary: Some people think hierarchy explains everything about an organization's operations. While all bureaucratic groups are hierarchical, the Public Works Department is a bureaucratic group that functions differently than most other bureaucratic groups.

Reasoning: All bureaucratic organizations are hierarchical, and the Public Works Department is a bureaucratic organization that operates differently than most others in its class.

Analysis: Since all bureaucratic organizations are hierarchical and the Public Works Department is bureaucratic, we can logically conclude that the Public Works Department is hierarchical. The stimulus sets up a contrast: Public Works and 'most other' bureaucratic organizations are all hierarchical, yet they operate differently. This suggests that hierarchy alone does not dictate a uniform way of operating. Look for an answer that synthesizes these facts to show that hierarchy is not the sole determinant of organizational behavior.
