B.5.FM:4.1 - Recover the contrast the answer must resolve

State what alternatives the answer should distinguish: whether an intervention can reach a target, which arrangement could explain an observation, how many constructions meet a rule, or what condition prevents a result.

Inspect a small instance or the available arrangement. Describe the supplied facts separately from the account you propose. Ask what changes between the cases that matter. The first question can be provisional; preserve a new question when the attempted construction reveals a more useful distinction.

If the participant cannot yet express what differs or matters, B.5.EA helps articulate that contribution before model construction. Return here when the resulting distinction permits a question or contrast; do not require this preliminary work when the contrast is already usable.

When the current account is clear but leaves you unsure which question matters, the scheme comparison in :4.2.1 can expose a useful distinction. A discovered question may already have an adequate answer; use it without requiring a larger model.

An existing answer may already resolve the contrast. Use it under its conditions. C.11.DUA helps when obtaining more information or refining a model competes with acting on a sufficient answer.
