Estimating the risks of radiation escaping from a nuclear power plant is ______ question, but one whose answer then becomes part of a value-laden, emotionally charged policy debate about whether to construct such a plant.
【正确答案】
E
【答案解析】- 方程等号：but但是，表示转折，句意取反。 - 强词和对应：question和debate构成同义重复，因此空格和emotionally charged policy根据but取反，体现估计核电站泄露的风险是“非情绪化的”问题。incomprehensible难以理解的，undefined不确定的，irresponsible不负责任的，divisive造成分裂的，technical技术上的。technical的英文释义为technical means involving the sorts of machines，processes，and materials that are used in industry,transport，and communications。答案选E。
