Reading the passage
The benefits we remember are using materials more efficiently and producing less waste. This is an EXCEPT question: four answers should describe benefits actually mentioned. We need the extra claim.
Working the answers
- A
Minimizing waste is one of the stated goals of the industrial ecosystem.
- B
Harmful by-products remain, but the recycling example says they occur at much lower levels. A reduction is supported; elimination would be different.
- CCorrect
No increase in alternative energy sources is proposed. The text discusses optimizing energy use and switching to alternative materials. Neither tells us factories would use more solar, wind, or other alternative power sources.
- D
The second paragraph explicitly says consumption of energy and materials is “optimized.” Getting more use from the materials fits that benefit.
- E
Turning one process's waste into another's raw material is the central proposal. It makes better use of what would otherwise be discarded.
