One question asks: What line of Coode is correct when
initializing an Instance of the Object Dog.
One option is Animal spot = new Dog();
I don't want to cherrypick, but since Dog is a Subtyp of Animal it is formally
correct and possible to store it in a Variable of the super class.
It's not relevant at this point of the course, but that mistake should be avoided as soon as possible
(I'm german, so please excuse possible spelling / term mixups)
