I would like help with this too

Hi, Im not sure if this is a conditional argument- that is, I don't see a useful way to put this into if/then terms. When this happens, I would try to get a general understanding of the argument. We are told that to achieve an effect, someone adds a specific thing, and that done well, we cannot tell which specific thing was added, so none of the additives are irreplaceable. This high-level understanding of the argument may be helpful.

Could you explain why answer choices D and E are incorrect?

Hi, In the initial argument, the author concludes that if done properly, it is impossible to know the specific thing that caused an outcome. D is the opposite of this, it is saying that each specific thing is critical and irreplaceable, where the argument said that each one is replaceable. E is just an entirely different argument, it has nothing to do with the replaceability of given elements.
