I got the 2nd and 3rd blank correct here. I am confused as to why the 1st blank is chaotic and not fabricated. If the observed patters could in reality be specious, doesn’t it kinda hints that the system is a deceiving one?
Why do you think a fabricated system will have coincidences bound to occur? Coincidences are genuine and fabricated quite literally means invented to deceive.
The meaning of the sentence, as I view it, is that chaotic systems can sometimes appear to have patterns because the coincidences (which are bound to happen in a chaotic system) can be misread as patterns.
