If some S are not P, then there must be an X in the non-overlapping portion of the S circle (Area 1 in the diagram) that does not intersect with the P circle. However, we cannot say anything about whether there may be any S's in the overlapping portion of the S and P circles (Area 2 in the diagram). Therefore, the correct choice is B, indicating that there is an X in Area 1.
