The author’s tone toward technology in the renewable energy discussion is best described as?

• A. Jubilant and uncritical.
• B. Skeptical and dismissive.
• C. Cautiously optimistic.
• D. Indifferent.

Answer: (C)

Think of tone as the author's attitude toward what's being discussed. When someone talks about technology in renewable energy with hope for progress but also awareness of real obstacles, that’s a cautiously optimistic stance. The author would acknowledge advances—like improved efficiency, lower costs, and growing deployment—while also pointing out challenges such as storage, grid integration, and policy or funding needs. This blend of belief in potential and careful attention to hurdles explains why a cautiously optimistic description fits best. The other extremes—exuberant, uncritical praise; outright doubt; or indifference—don’t match the sense of balanced confidence and realism conveyed here.
