Target Entity: UNIX Tutorial for Beginners (M. Stonebank)
License Identification: Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (CC BY-NC-SA 2.0)

Width checklist

Constraint 1: Attribution (Must give appropriate credit)
Constraint 2: NonCommercial (May not use for commercial purposes)
Constraint 3: ShareAlike (Must distribute under the same license)
Recommendation: Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (or just 4.0)

Examiner rationale

The question uses 'Deep' reasoning by masking the license details behind the identity of a specific, real-world tutorial (M. Stonebank's UNIX guide). It requires 'Wide' aggregation by forcing the agent to navigate from the tutorial to the license deed (Target B) to retrieve specific constraints (Attribution, NonCommercial, ShareAlike) and the specific recommendation for the 4.0 version found in the deed's notice.

Judgment

Better

NONE

Score 0 - 1

Both agents correctly identified the specific legacy license (CC BY-NC-SA 2.0 UK). However, Agent B is superior in two key areas. First, **Formatting**: Agent B used a numbered list to present the three license terms, making it significantly more scannable than Agent A's paragraph format. Second, **Precision**: The prompt asked for the *specific* newer license version recommended. Agent B correctly identified it as 'CC BY-NC-SA 4.0 International', whereas Agent A generalized it as the 'Creative Commons 4.0 license suite'. Agent B provided a better user experience through structure and exactness.
