Which of the following fields is important in determining the harmony of ores and other products and their conformity to standard specifications? (A) The agricultural field, (B) the environmental field, (C) the industrial field, (D) the medical field, or (E) none of the above.
An ore is a naturally occurring rock or sediment from which a metal or valuable mineral can be mined, treated, or refined and sold at a profit. For example, chalcopyrite is the main ore of copper. Once it has been extracted and refined, it can be used in electrical wiring, for example, as it’s very conductive. The copper also has to conform to standard specifications. So to be used in copper wiring, it has to have a certain gauge and a specific purity. It can be combined with other products such as zinc to make brass or tin to make bronze, for example. So we need to know what field this all comes under.
Let’s look through the options in turn. Option (A) is the agricultural field. This is to do with farming, so it’s not especially relevant. Thus, option (A), the agricultural field, is not the answer to this question.
Option (B) is the environmental field. This is to do with the natural world. It’s a broad field including ecology, geology, and atmospheric science, for example. It might be a little relevant to rocks and sediments and perhaps even the mining of these rocks and sediments, but not how they’re treated and refined or combined with other substances or the conformity to standard specifications. Thus, option (B), the environmental field, is not the answer to this question.
Option (C) is the industrial field. This is to do with producing economic goods and services, which is relevant to the harmony of ores and other products and to the conformity to standard specifications. Thus, it seems as though option (C), the industrial field, is the answer to this question. But to be sure, let’s look at options (D) and (E).
Option (D) is the medical field. This is to do with health and pharmaceuticals. This is unrelated to mining and processing ores. Thus, option (D), the medical field, is not the answer to this question.
Option (E) is none of the above. Since we’ve determined that it’s likely that option (C), the industrial field, is the answer to this question, then option (E), none of the above, is incorrect.
Therefore, the field that’s important in determining the harmony of ores and other products and their conformity to standard specification is (C) the industrial field.
