正好遇到还有一题,
(Originally developed for detecting air pollutants, a technique called proton-induced X-ray emission,
which can quickly analyze the chemical elements in almost any substance without destroying it,) is finding uses in medicine, archaeology, and criminology.
答案说这个表述是正确的,并且 which指代的是technique。。。为什么这里which 不指代X-ray Emission呢? 不是更近吗? 怎么看出来呢? 多谢
