UNIX / Linux Tutorial for Beginners

Step 2

Question

An early-2000s beginner tutorial on the UNIX/Linux operating system created by a UK academic is distributed under a Creative Commons license that permits sharing and adaptation but restricts commercial use and requires derivative works to use the same license. Identify the exact version of this license and provide a detailed explanation of: (1) the freedoms it grants, (2) the specific conditions users must follow (including attribution, commercial restrictions, and share-alike requirements), (3) any stated limitations or disclaimers (such as public domain exceptions or warranty notices), and (4) the notice comparing this version to the newer 4.0 version, including the recommended upgrade and the canonical URL associated with the older license version.

Answer length: 200-300 words.

Depth checklist

Creative Commons Attribution-NonCommercial-ShareAlike 2.0 License (CC BY-NC-SA 2.0) correctly identified as matching the tutorial’s share, adapt, noncommercial, and share-alike conditions
Recognition that the license includes an official notice comparing it to version 4.0 and recommending the newer 4.0 license

Width checklist

Correct identification of sharing and adaptation freedoms
Statement that the licensor cannot revoke freedoms if terms are followed
Attribution requirement (credit, link to license, indicate changes)
NonCommercial restriction
ShareAlike requirement
No additional restrictions clause
Public domain / exception or limitation clause
No warranties disclaimer
Notice that this is an older version of the license
Statement recommending use of the 4.0 version
Canonical URL for the 2.0 license version

Examiner rationale

The question uses contextual clues (early-2000s UNIX/Linux beginner tutorial by a UK academic with share/adapt but noncommercial and share-alike restrictions) to indirectly point to the CC BY-NC-SA 2.0 license without naming it (Deep logic). It then requires aggregation of multiple scattered elements from the license deed and notice—freedoms, conditions, disclaimers, version comparison, recommendation of 4.0, and the canonical URL—ensuring broad information retrieval across the full license summary (Wide scope).

Judgment

Tie

NONE

Score 0 - 0

First, Deep Logic: Both agents correctly identify the license as Creative Commons Attribution-NonCommercial-ShareAlike 2.0 UK: England & Wales (CC BY-NC-SA 2.0 UK) and recognize the official notice recommending upgrade to version 4.0. Both pass the core entity check. Second, Width/Completeness: Both cover the required freedoms (share/adapt), attribution requirements (credit, link, indicate changes), NonCommercial restriction, ShareAlike requirement, public domain/exception clause, warranty disclaimer, older-version notice, recommendation of 4.0, and provide the canonical 2.0 UK URL. Both slightly miss explicitly stating the “no additional restrictions” clause and do not clearly quote the irrevocability clause (“licensor cannot revoke freedoms if terms are followed”), though B implies permanence. These are parallel minor omissions. Finally, User Experience & Presentation: Both responses are well-structured, scannable, and formatted with clear section headers and bullet points. Agent A is slightly more structured; Agent B adds helpful context about the yellow banner and directly quotes the upgrade recommendation. Citation density is comparable. Neither significantly outperforms the other in clarity or completeness. Overall, both provide accurate, comprehensive, and user-friendly answers with only minor shared omissions — a High Quality Tie.
