What is most remarkable about the proposal made by the two scientists?
What is the biggest problem with hydrogen-powered cars?
选项
A、There is no cheap source of hydrogen.
B、There might be a safety problem in hydrogen production.
C、They may still be a cause of global warming.
D、They are not suitable for long-distance travel.
答案
C
解析
第三段中说:Hydrogen-powered cars emit no carbon dioxide,but producing hydrogen requires energy,and if that energy comes from coal-fired power plants,then the problem has not been solved.意为:氢气动力车不会释放二氧化碳,但产生氢气需要能量,如果这能量是来自火力发电厂,那还是无法解决问题。由此可知C项为正确答案,其他选项为干扰项。
