E.10:9.10 - present, represent, representation, representative

Recover what is being shown, described, modelled, instantiated, sampled or acted for, and which relation the current sentence asserts. The shared word can conceal different questions. A presentation can be an act of communicating or its material; a representation can be an expression used to reason about a subject; a representative can be a selected case, a statistical sample or an authorized participant.

When the intended participants and predicate are already clear, keep ordinary wording and use the subject rule. For a remaining ambiguity, E.10.ARCH:3 recovers them. C.2.P supplies source, content and publication distinctions; C.37 supplies representation choice; C.29 supplies mathematical correspondence and returned inference. Kind membership, composition, statistical inference and acting under an assignment retain their own governing rules.

When a sentence relies on a “representative” example or fragment, recover the claim it supports and the basis of that support. A case chosen to illustrate an operation and a sample used for population inference have different grounds. Use C.39.QR when the unresolved question is what the obtained result establishes for the originating assignment; use C.39.WA when that assignment requires the still-missing explanation of a whole subject. Select a useful case by its contribution to the explanation, while preserving the general proposition and its grounds.
