1. Expand in a two-element universe (the elements are named 'a' and 'b')

**Transcription for Educational Website** The image contains formal logic expressions structured as follows: (a) \((\exists x) ((A x \rightarrow B d) \rightarrow K y)\) (b) \((\exists x) \sim (D x \lor C y)\) (c) \(\sim (\forall x) (D y \rightarrow (H x \lor \sim G a))\) **Explanation:** - **Universal and Existential Quantifiers:** - \(\exists\) denotes "there exists" or "for some". - \(\forall\) denotes "for all". - **Logical Operators:** - \(\rightarrow\) represents implication, meaning "if...then". - \(\lor\) represents a logical "or". - \(\sim\) denotes negation, meaning "not". Each expression involves the use of logical operators combined with quantifiers, forming statements that typically relate to propositions in mathematical logic or predicate calculus.
