Question

BlackTom AI · Accepted Answer

The speaker explicitly states that carbon capture “needs further development to become more efficient and cost‑effective,” so the correct choice is C: further development.

1) Relevant knowledge points and concepts
- Difference between current performance and required improvements: “efficiency” and “cost‑effectiveness” are outcomes of technological maturity and R&D.
- What each option implies: (a) building large projects, (b) directly lowering costs, (c) advancing the technology through development.

2) Step‑by‑step reasoning
- The passage (highlighted in the image) links the technology’s shortcomings—insufficient efficiency and cost‑effectiveness—to a need for further work on the technology itself.
- “Further development” is the immediate remedy the speaker names; improving efficiency and cost profiles follows from development, not simply from scale-up or a one‑time cost cut.

3) Intermediate logical steps
- If the speaker had meant (a) large‑scale projects, the statement would indicate that scaling up is the main barrier. Instead, the speaker says there are only a few large projects because the tech is not yet efficient/cost‑effective — i.e., scale is a consequence, not the primary need.
- If the speaker had meant (b) lower costs, they would have stated that cost reduction alone is required. Instead, cost‑effectiveness is described as a target achieved by further development of the technology.

4) Why the correct answer is correct
- The quoted wording directly names “further development” as the action required so the technology becomes more efficient and cost‑effective. That is a precise match to option C.

5) Why the other options are incorrect
- (a) large‑scale projects: the speaker explains few exist because the tech isn’t ready; they do not claim scale alone will fix the problems.
- (b) lower costs: cost reduction is a goal, but the speaker attributes achieving that goal to further development rather than simply demanding lower costs now.

Conclusion: The best answer is C (further development), which matches the provided correct answer.
