hi! (fair warning, this a question from is the genuinely tragic mirrors passage btw): for the life of me, i cannot figure out why c is the right choice for this one. i think it's largely because i literally just don't understand what the answer choice means. like genuinely sentence/word-wise i have no friggin clue.

on a theoretical level, i get that the idea of "separating observers from scientific phenomenon" as it's discussed in the text + how this informs the tendency of scientists to prefer certain explanations for phenomena. but i don't understand how that idea is conveyed by the words of answer choice c. answer c reads: "One explanation of what mirrors do reveals the traditional tendency of physicists to separate a phenomenon to be explained from the observer of a phenomenon."

i've been racking my head trying to parse the bolded part word-by-word but i genuinely can't figure it out. isn't the point the text is making that science ppl prefer explanations that don't rely on the observer? how does "separating a phenomenon •••to be explained••• from the observer of a phenomenon" do that?? if someone could even just help break down what this part means that would be useful lol. ty in advance
