The cover dates this paper to 2021; the public attachment is named 2020. The supplied copy has two missing figures on paper page 3 and no recoverable content on paper pages 4–5. The solutions below cover all recoverable labelled parts, with explicit limits where a missing figure prevents a numerical or labelled identification. No questions from the absent pages have been reconstructed.

TODO: recover source pages 4–5 and the missing track and resonance plots needed for question 2(c)–(e). Their source-specific conclusions remain incomplete.
