Conclusions:

I. Some Boxes are Scales – False (Since, there is no direct relation between them so it is not definitely true).

II. Some Pens can be Scales – True (Since, there is no direct relation between them so it can be possible).

III. No Books are Erasers – False (Since, there is no direct relation between them so it is not definitely true)

IV. Some Books are Erasers – False (Since, there is no direct relation between them so it is not definitely true)

Since, conclusion III and IV are complementary to each other.

Hence, both conclusion II and either conclusion III or conclusion IV follows.
