Assume that getBiologicalClass$()$ is a class method in the Cat class. What is demonstrated by the following line of code?

Cat.getBiologicalClass$()$;

If 'calculate' is an instance method in the appropriate class$($es$),$ then lines $3$ and $4$ in the following code are an example of the polymorphic concept 'late binding' and the code executed as a result of Line $3$ may be different than the code executed as a result of Line $4.$
