(4 points) Suppose you are at a design review (a meeting where programmers get together to discuss each other's designs and programs).  One programmer says, "A and B implement C, and D extends B".  Everyone nods in understanding.  Then they all look at you.  Convince them that you understand, too.  Draw 4 boxes, one each for A, B, C, and D, and draw appropriate arrows between them to indicate their relationships.  If you are unsure of the official notation, write a short note or label on each arrow to explain.

Draw C highest on the page, then A and B below C, then D below that.

3 arrows, from A to C, from B to C, D to B
