C.2.8:2 - Problem
How can an author or evaluator compare structural recovery while distinguishing the account, its expression, the reader and the conditions of extraction?
A diagram may make dependencies visible without changing the described system. An added prerequisite explanation may change the claims as well as their expression. Two complete accounts may expose different structures within a short reading budget. A successful response can also depend on help that was unavailable for another response. The comparison needs to preserve these differences while retaining one meaning for structural amount.
