graphs and trees

Question

Suppose that in a group of eight people, A , B , C , D , E , F , G , H each going shopping with at least one of the gang. A with B , C with D and E , B with E , F with G and H , H and B , E and A , B and C.
a) Draw a graph to show these shopping trips.

Answer 1

I'm sure this class is over already, but I'm leaving this here for posterity:

 

Typically when you're asked to draw a graph of connections, it would look something like a network map:

 

 

         G----F-----H

                      /

       A---------B

      /           /   \

  E ----------      \

    \                     \

      ---------------- C-------->D

 

I'm unsure if these are meant to be directional, because "B and C" is mentioned, but C doesn't include B (only D and E), and B is mentioned twice.  If they're directional than any of those points should end in an arrow showing the direction (I included one for the "CD" connection for "C with D and E")
