Edy, please mention the course name in the general forum.  I take it this is about Math Challenge II-A.

This question doesn't give you a diagram, and based on the description of the question, the regular hexagon is $ABCDEF$ and the regular pentagon is $EFGHI$, so they share one edge $EF$.  But there are two possible ways to draw the diagram based on this information.  That is why there are two possible values for $\angle GAF$.
