For the discourse in the paragraph below, identify the domain of the discourse, and the

predicates $($and functions if any$)$ used by the discourse and their interpretation. Then build a

knowledge$-$base $($KB$)$ of the propositions stated in the discourse in CNF and clausal form. Finally,

using the binary resolution, see whether the sentence $$Herbert should think twice$$ can be

satisfied in the resulting knowledge$-$base $($KB$)$ or not. Note that there are no variables used here

and the discourse is only about specific objects, i$.$e$.,$ Herbert, Herbert$$s wife, Hebert$$s apartment,

and Herbert$$s dog.

If Herbert can take the apartment only if he divorces his wife, then he should think

twice. If Herbert keeps Fido, then he cannot take the apartment. Herbert's wife insists

on keeping Fido. If Herbert does not keep Fido, then he will divorce his wife provided

that she insists on keeping Fido.
