Part II: Semantic Networks a) i) A class in this network is Settlement. ii) An individual is this network is Florence. iii) Settlement has the property number of universities (0) and capital of (Nowhere). Both these properties can be overridden and an example of this is London which is an instance of City which in turn is a subclass of Settlement. From Settlement, City gets the properties number of university (0) and the capital of (Nowhere). City overrides the property of number of universities and sets it to 1, which
