WitCH 72: High Significance

Here is one more from the 2019 Specialist Exam 2, once again courtesy of student PURJ (who is vetting the exams much better than the exam vetters). It consists of the last four parts of Q6, the final question on the exam, concerning a machine that packages noodles. The answers from the examination report appear below the questions.

WitCH 70: Troubled Relations

This is not an old one. It is from the 2019 Specialist Exam 2 and comes courtesy of student PURJ, who previously contributed to the discussion here.

WitCH 67: Rooted

Our final 2021 NHT WitCH is the final question from the Specialist Exam 1.

UPDATE (29/08/21)

Sigh. We really hate updating WitCHes.* We have about a hundred of these things to do, and we’re generally thinking of the updating as a task for retirement or, better, for a reincarnation. However these NHT WitCHes, and this one in particular, have highlighted a degree of confusion. So, alas, it seems worthwhile sorting out the issues while the issues are in mind.
