Of course, we would expect that the choices for B and C would change with the new scale. But should the scale in Survey II make any difference to how often choice A is used? Choice A is identical between the two questionnaires, yet we would find the frequency of A being chosen would be lower in Survey II than Survey I.1 In this example, you could avoid partition dependence just by calibrating them and ask for an estimate of the actual quantity. If that was not practical, you might need to use more than one survey to minimize that effect.
