Question 30. An explorer wants to find a path through the maze shown from the point marked start to the point marked finish.  She can only move horizontally or vertically, and she can only pass through white circles. She also has to pass through all of the white circles exactly once.  When she reaches the circle marked X, what will her next move be? Let's draw out our maze. First, we know that from the start, she will have to go this way.  Now, knowing that she can only move horizontally or vertically, there are some circles that only have one potential path, since they have to be entered and left in a specific way.  These are marked green. These we can mark out with a path, since we know this is the way she will have to travel.  So, following this red line from the start, we can continue on, making sure that we hit every white circle.  First, she will move up, then to the right, then down, then to the right, and so on and so forth.  Once she reaches the red circle that we have marked, she will be turning right, and at this circle, to connect with the rest of the path, she will have to move down.  The answer will be B.
