sure, i can explain it for you. the circled letters are cardinal directions (N,W,S,E) and you need to follow them in the "detours". for example, 1A's detour answer is WASHERS because after WAS, you move "south" (because S is circled) to HE and then move "east" (because E is circled) to RS, which forms WASHERS. this is the same idea for 9A's detour, except instead of moving south and east you are moving north and east. hope this helps!
