I. Some copies are envelopes → True (as all envelopes are copies, implies some copies are envelopes)

II. Some postcards are copies → False (it is possible but not definite as shown in the above figure that no postcard is copy is possible)

III. Some cards are copies → True (as some cards are envelopes and, all envelopes are copies, implies some cards are copies)
