The reason for two columns is because this conveyor uses a dual id system because to have the effect that the conveyor keeps running on forever it goes one set of flags than the next each with a path id and a and b so to make the whole thing light up it needs 2 answers for each flag.
Also... just looked at my quiz analytics and saw I'm getting an average of a take and a half per day lol. Need to make more quizzes ig
p.s: Look out we are on the same quiz making page
Uh no I need to speed up my quiz-making schedule...
