I am in the process of packing boxes onto my lorry (truck). I cannot load box A onto the lorry because that would exceed the maximum weight allowance. On the other hand, if I unloaded box B from the lorry, I would be able to load box C on to the lorry without
exceeding the allowance.
Which of the following must be true?
I. If I didn't unload any boxes (including box B), then I wouldn't be able
to load box C onto the lorry.
II. The remaining weight that can be loaded onto the lorry must be at
least as big as the difference in weight between boxes B and C.
III. The weight of box A must be bigger than the difference in weight of
boxes B and C
I and II only
II and III only
