问题 The wavelengths of light and radio waves, unlike high energy gamma radiation, are much shorter. [br]  
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.
Foreign laborers, especially Asian ones earning low wages, are pictured as working willingly for American capitalists abroad who pay slightly better than average wages; while the former learn otherwise inaccessible technology and produce sophisticated goods that compete with domestic American goods, even allowing for shipping charges and import duties.
选项 A、true
B、false
答案 B
解析 语义逻辑推理判断。根据原文可知，对于美国海外资本家来说使用外国劳动力，尤其是亚洲国家的劳动力费用非常低。而这些国家却从此得到先进技术，生产尖端产品。这些产品，即使在增加运费和进口税的水平上仍可与美国国内制造的产品竞争。由此可见海外美国人使用亚洲劳动力制造的产品，即使有运费和进口税的压力，仍然可与美国本土制造的产品竞争。显然这与题干中所言进口美国的商品免除税费的说法不相符。因此，题干的说法是错误的。
