Section C — Applied Analysis (5 questions)#

21. You compare snapshots from 2014 and 2019. The navigation changed and the layout shifted. What drift level is this? Why?#

Your answer:

22. A webpage has snapshots in 2012, 2013, 2014, 2017, 2018. Identify any continuity breaks and explain their significance.#

Your answer:

23. A site switches from HTML to PDF between 2016 and 2019. What does this imply about stability?#

Your answer:

24. A site undergoes a CMS migration in 2020. Which operator detects this, and how does it affect drift?#

Your answer:

25. Using drift, continuity, and substrate stability, explain how you would choose the most reliable snapshot for a webpage.#

Answer Key (Teacher Version)#

Section A — Multiple Choice#

1 — B
2 — B
3 — C
4 — A
5 — C
6 — B
7 — C
8 — B
9 — A
10 — B

Section B — Short Answer#

  1. Drift = structural change between snapshots.
  2. Continuity kernel = elements that stay the same across snapshots.
  3. Minor drift examples: small CSS changes, slight layout adjustments.
  4. High drift examples: redesign, CMS migration.
  5. PDFs preserve layout and do not depend on live HTML/CSS.
  6. WAYBACK_OPERATOR shows snapshot timeline and drift.
  7. PRESERVATION_OPERATOR evaluates substrate stability and drift risk.
  8. Regime shift = major structural change (e.g., static → CMS).
  9. Stable substrates produce more reliable snapshots.
  10. COLLECTION_OPERATOR identifies IA collection and related objects.

Section C — Applied Analysis#

  1. Moderate drift — navigation + layout changes.
  2. Missing 2015–2016 = continuity break → uncertainty.
  3. PDF layer increases stability.
  4. LINEAGE_OPERATOR detects CMS migration → high drift.
  5. Choose snapshot with low drift, strong continuity, stable substrate.
