All I can think of is that "how do you set variables in the base class
to be all private" is meant as if it were followed with "...to the
derived class" (since the sentence begins, "From the point of view of
a derived class"). So another way of asking this would be, "How can a
derived class make sure that all the accessible variables it inherits
from its base class are not accessible to its further derived
classes". That would be via private inheritance:
        class B : private A {
                ...
        };
