How can a verbal reasoning question be solved with Mathematica?
To look for a pattern,we get the character codes:
cc= ToCharacterCode["KDXPNGVNQJTLTM"]

Something like:
n = 50;
rays = Table[{Dashing[Flatten@Table[{RandomReal[.2], .01}, {10}]],
, Line[{{0, 0},
If[EvenQ[n ph/Pi], 2, RandomReal[{0.2, 0.9}]] {Sin[ph],
Cos[ph]}}]}, {ph, …
