Correct Answer: (A)
This game introduces the idea of reciprocal causation. For example, the constraint that says “If $A$, then $B$, and if $B$, then $A$” should be transcribed in one of the following two ways, based on the configurations of the other variables in the diagram:
You will run into reciprocal causation in the final constraint of this logic game. Here are the final diagrams that you should create:
Notice how the reciprocal causation constraints are diagrammed. Be aware of the implications of these constraints. For instance, if $B$ is not sent (diagram B), then $A$ cannot be sent and $G$ must be sent. In diagram A, if $B$ is sent, then $A$ and $H$ are sent.
Which of the following could be a complete group of the negotiators?
(A) $F, A, H,$ and $B$ could all be sent.
(B) If $H$ is not sent, then $E$ must be sent.
(C) If $A$ is sent, then $B$ must be sent.
(D) If $A$ is sent, then $H$ must be sent.
(A) is the correct answer.
