Reading the passage
The clearest obstacle is the one named at the end: current technology can't yet give every manufacturing output an economically useful role. I also wondered whether countries would agree to change their practices. But this question asks for an obstacle actually stated, not one we can imagine.
Working the answers
- A
We aren't told that manufacturers refuse to change. That is a possible concern, not a stated obstacle.
- B
No refusal to lower living standards is described. The proposed response is to change manufacturing practices.
- C
The final paragraph calls on developing nations to bypass older technologies; it doesn't say they are unwilling to do so.
- DCorrect
The ideal requires a financially feasible use for each output, but existing technology often cannot deliver that (paragraph 4). Profitable use captures that economic requirement.
- E
We aren't told these systems produce too few goods. The stated limitation concerns finding uses for every output.
