OK so try this.  You do know what a compass and the compass points are?  North-South, East-West?  So, place an object on the South point move it to the East point in a straight line.  Next from East to North, from North to West and Finally from West to South.  That is the same movements as done on a Baseball Diamond.  But the point is this is a test of your knowledge of the Poser constraint system.  So, the test is to make the object travel to the 4 points using only 3 constraints.  And yes, this is related to the Poser Cloth as one of the parts of it is the constraint system.  The other part is the Bullet physics part and how it relates to mesh handling.  So, the cloth will either fall to the ground (as best it can) if it has no constraints on it or the other extreme is that it will be rigid and none moving.  In between those two points is where you want to be with your stiffness.  Since a mesh that is painted and has a constraint if allowed to would return to it starting point at least in the Physics Cloth tab.
