问题 The wavelengths of light and radio waves, unlike high energy gamma radiation, are much shorter.
Nuclear energy is released at the sun’s center as high energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength.
选项 A、true
B、false
答案 B
解析 比较结构的理解。本题要求听者分辨清所比较之物及其对比关系。原文谈到nuclear energy(核能)时，将其解释为high energy gamma radiation(高能伽马辐射)，像光波和无线电波一样属于一种光磁射线，只是其波长更短一些。由此可见，题干说光波和无线电波的波长短得多的说法是错误的。
