Final answer:
A 'vague expression' allows for varying degrees of interpretation in covering a given situation, unlike the more precise cognitive claims, which are verifiable as true or false, or emotive meanings which express personal feelings.
Step-by-step explanation:
Among the linguistic expressions listed, vague expression allows for degrees to which the expression covers a given situation. Vague expressions are not precise; they allow for a range of interpretations or gradations, unlike cognitive claims, which assert propositional knowledge that should be verifiable as true or false. For instance, the word “expensive” is vague, as it can pertain to various degrees of cost according to different perspectives.
Emotive meaning involves expressions that convey personal feelings and attitudes, which are not subject to true or false evaluations. Ambiguous meaning entails a phrase or sentence that has multiple interpretations, but this does not speak to degrees of a situation. Cognitive claims are concerned with assertions that are either true or false, related to propositional knowledge, such as logical or empirical claims. Lastly, value claims express a judgment of worth or importance, often connected to emotive meaning.
