The statement "Some M are not P" means that there is at least one thing that is M but not P. This can be represented by shading area 3 in the Venn diagram. 
The statement "No S are M" means that there is no overlap between S and M. This can be represented by leaving areas 1 and 2 blank. 
Combining these two statements, we can see that there must be some S that are not P - they are in area 2, outside of the shaded area 3. There is no reason to shade area 1, and shading areas 4-7 would contradict the given statements. The X does not appear in any of the areas shaded in this diagram.
