Question 1: True or false

mediumAI-checkedKnowledge Representation & Reasoning

"Every fox is cute; therefore all vixens are cute" is valid in English, because every vixen is necessarily a fox. Its FOL symbolization ∀x (F(x)→C(x)) ∴ ∀x (V(x)→C(x))\forall x\,(F(x) \to C(x)) \ \therefore\ \forall x\,(V(x) \to C(x)) has a counter-model. True or false: that counter-model shows the English argument is invalid.
