The statement "Some S are P" means that there is at least one member of the group S that is also a member of the group P. This can be represented in a Venn diagram by placing an X in the overlap between S and P (Area 2). There may or may not be other members of S and/or P that are not in the overlap, so we cannot shade any areas except for the overlap where we know there is at least one member. Therefore, the correct choice is C, which shows an X in Area 2 and no other marks.
