Examiner rationale

The question uses Deep Logic by requiring the agent to deduce the specific individual holding a leadership role within the provided entity (California Poison Control System) without naming them. It requires Wide Aggregation by demanding linked details about the individual's credentials and the specific administrative body (School) managing the system.

Judgment

Better

NONE

Score 1 - 0

Both agents correctly identified the Executive Director (Stuart E. Heard, PharmD) and the administering school (UCSF School of Pharmacy), passing the Deep Logic and Wide Aggregation checklists. However, Agent A is the clear winner based on User Utility and Presentation. Agent A provided a complete response with a 'References' section that corresponded to its in-text citations. Agent B included in-text citation markers (e.g., [1]) but failed to generate the actual reference list, making the citations non-functional (hallucinated citation format). Additionally, Agent A provided helpful context about the system's structure (4 call centers) while remaining concise.
