The statement "All M are P" means that M is completely encompassed by P. Therefore, areas 1 and 2 (which represent M) must be shaded. However, there is no information about S, so it could be located in either area 3 or 4 (which represent non-P). Therefore, an X is placed in area 3 to indicate that S may or may not be there.
