问题 According to the first paragraph, one of the warnings given by the scientists is that
According to the fifth paragraph, what is the suggested method to control underground fires?

选项 A、Using remote sensing technique.
B、Controlling the release of carbon dioxide.
C、Making the soil heat resistant.
D、Cutting off the oxygen supply.

答案D

解析 A是错误的选项,因为Using remote sensing techniques 是estimate how much carbon dioxide these fires are emitting 的方法,而不是控制地下火的技术。该段中没有提到B、C的内容。从句which is designed to be pumped into the coal fire to cut off the oxygen supply中的 which 指 a heat-resistant grout,将它注入地下可切断氧气供给,达到控制地下火燃烧的目的。所以,D是答案。
