Your examples use the indefinite article, but the first example in the abstract uses the definite article. (The second, after rephrasing, also does.) Contrast "Mars is the fourth planet from the Sun" and "Mars is a planet".

With GOFAI (e.g. Cyc, SHRDLU), you'd distinguish between "X is a Y" and "X is the Y" and store them differently, and if you got an incorrect answer you'd have a good idea where to look for your bug. With a LLM, you have a black box with billions of connexion weights and (correct me if I'm wrong) your only recourse is to retrain it on data which distinguishes the two cases, but even that might get lost in the noise, or cause problems somewhere else.
