How can we logically explain that the area of partial insurance is below the full insurance line?

 Full insurance requires q < IH - IS for a given value of q. To turn this into partial insurance, we need a q (partial) lower than q to satisfy q(partial) < IH - IS So for every point on the full insurance curve we lower q which would lower the intersection point between IH' and IS' at every level of IH' and all these points are below the full insurance line.
 Full insurance requires q = IH - IS for a given value of q. To turn this into partial insurance, we need a q (partial) HIGHER than q to satisfy q(partial) < IH - IS So for every point on the full insurance curve we lower q which would lower the intersection point between IH' and IS' at every level of IH' and all these points are below the full insurance line.
 Full insurance requires q = IH - IS for a given value of q. To turn this into partial insurance, we need a q (partial) LOWER than q to satisfy q(partial) > IH - IS So for every point on the full insurance curve we lower q which would lower the intersection point between IH' and IS' at every level of IH' and all these points are below the full insurance line.
 Full insurance requires q = IH - IS for a given value of q. To turn this into partial insurance, we need a q (partial) LOWER than q to satisfy q(partial) < IH - IS So for every point on the full insurance curve we INCREASE q which would lower the intersection point between IH' and IS' at every level of IH' and all these points are below the full insurance line.

Given a point E in an IH-IS space, if r decreases and q decreases where is the new point (E') relative to point E? a. above left of point E b. above right of point E c. below left of point E d. below right of point E e. could either be above right, parallel right, or below right of point E

Answer : The point E' will lie to the c. below left of point E as given that both r decreases and q decreases at this new point (E') relative to point E which is only possible to the left down point to E as shown in the diagram below:
