Good comments by all. I think this is exactly that kind of question, to
see how the candidate or certification taker responds and thinks.

One of the first things I'd question is the existence of the abstract
class. Not that we know how IStorable is defined, but intuitively I'd
want a "store" method to be in the interface, with documentation. Only
if there were substantial implementation commonality would I bother with
the abstract class.

In the real world I (we) would know what the problem actually is, not be
presented with part of a flawed solution.
