PT14.S4.Q19 - when permits for the discharge of chemicals

edited September 2017 in Logical Reasoning 12 karma

Are we supposed to assume that these chemicals are initially "harmless" or that the dilution process caused them to become harmless? There is nothing in the passage discussing whether or not the chemicals are harmless.

No other answer choice makes sense, but Answer choice A requires some form of assumption to be made.

some insight please.
