And because demand for this precious resource will grow, according to some, by over 40 percent by 2025, fueling the world’s economic【C5】______will take a lot more energy from every possible source.

【C10】

选项

答案O

解析 空格前面有形容词some和介词of,空格后面有needed to get started这样的定语修饰,因此,空格处需要填入名词,符合句意且可以与take搭配使用的名词为steps“步骤”,take steps意思为“采取行动”,因此steps为答案。名词备选词中,能够构成take some of这样结构的只有steps,其他名词均不能与take some of共用,构成符合文章上下文意思的表达,因此均可排除。
