B.5.RA:4.4a.2 - Compare consequential readings and try a scheme

Where the wording admits readings that change the support, make the alternatives explicit. Compare them with the actual assertions, the question under discussion, surrounding replies and any shared premise that can be established. Prefer the reading that accounts for those contributions with the fewest unsupported additions. Interpret the speaker reasonably, but do not improve a weak argument into a different strong one and attribute the improvement to them. Agreement with the conclusion is no reason to prefer a reading.

Ask a discriminating question when a reply is available: “By free, do you mean unbooked at that time or without a hire charge?” If the source cannot be consulted, preserve both live readings or limit the use to what they share. Choosing a provisional reading can be sufficient for examining its consequences; it does not resolve the remaining ambiguity.

An argumentation scheme describes a recurring arrangement of premises and conclusion. Try one as a hypothesis about the inference. Fill its places from the recovered claims and identify every place still missing. For expert opinion, find the relevant expertise, the actual assertion and the proposition it is offered to support. Someone who handles a booking calendar can instead know its entries through ordinary access. A professional title by itself does not establish either expertise about this question or knowledge of this occasion.

A missing scheme premise gives a question, not permission to invent its answer. Look for evidence that the source relies on it; if none is available, retain the gap, try a better-fitting scheme, or describe the inference directly. For instance, calling a new expense “a waste” need not invoke sunk costs. The latter reading needs past investment and a claim that stopping would waste that investment. An argument against an unnecessary future expense can have neither. Scheme selection follows the offered support, not the word that first caught the reader’s attention.
