The spirit in which we are asking these questions is not to demand definitive answers to them, but to make the point that many choices are possible. Indeed, as we shall see, many different responses to the above questions are exemplif ...

Such derived effects should be taken into account when combined with the inertia assumption, since they override the latter.
