B.5.RA:2 - Problem

An argument can be present without being usable by its reader. A reader may recognize each term yet miss why a lemma was introduced, where two premises must be used together, or how a local calculation establishes the general conclusion.

Reading each sentence fluently or checking isolated inferences leaves the overall method uncertain. Reading only the overview can hide a decisive unsupported transition. Either failure prevents useful transfer: the practitioner cannot tell what to use, which condition matters or where to ask for help.

The useful result is enough recovered reasoning to perform the intended use, or a localized gap whose resolution would make that use possible. This may be a conditional conclusion when a needed premise remains open.
