**Go up to **2 Interpretations and Models (with variables)

**Go forward to **Solution to part (b)

## Solution to part (a)

*Give one interpretation that is a model of **KB*.
*D = {x,y}* (this is true of all the interpretations.)

*phi(a) = x*, *phi(b)=x*, *phi(c)=x*.

*pi(p)(<x>)=TRUE.* *pi(p)(<y>)=TRUE.*

*pi(q)(<x>)=TRUE.* *pi(q)(<y>)=TRUE.*
