Explanation:

I. Some cups are not pencils → It's true. (Part of cup that is eraser is not pencil)

II. Some cups are not pens → It's true. P(art of cup that is eraser is not pen)

III. Some pencils are not cups → False (It is possible but not definite)

IV. No pen is eraser → It's true. (As no pencil is an eraser, Pen is part of the pencil so no pen is eraser)

Thus, only conclusion I, II and IV follow.
