这道题的d和e有什么区别，这里的during the twentieth century ,感觉没什么区别啊

12. Carbon monoxide levels in the atmosphere grew by enough of an increased percentage during the

twentieth century that it began to trap heat radiating from the Earth, and it caused the average

surface temperature to rise.

• Carbon monoxide levels in the atmosphere grew by enough of an increased percentage during the
  twentieth century that it began to trap heat radiating from the Earth, and it caused the average
  surface temperature to rise.
  
• Carbon monoxide levels in the atmosphere increased by enough of a percentage during the twentieth
  century that they began to trap heat radiating from the Earth, causing the average surface
  temperature to rise.
  
• Levels of atmospheric carbon monoxide increased sufficiently during the twentieth century to begin
  trapping heat radiating from the Earth, causing the average surface temperature to rise.
  
• Atmospheric carbon monoxide levels increased by a sufficient percentage during the twentieth century to begin trapping heat radiating from the Earth, which caused the average surface temperature to rise.
  
• Levels of carbon monoxide in the atmosphere during the twentieth century increased enough to begin
  trapping heat radiating from the Earth, causing the average surface temperature to rise.

逗号+which 是一个non essential modifier, 修饰的是之前最近的noun，所以在这里是'the Earth', 但是D这里的modifer 修饰的是一种结果，并不是一个名词，所以D 排除掉

D選項的during是修飾 increase整件事的時間；而E選項的during則是修飾名詞 levels of carbon
兩者比較會有句意上根本的差別。但也沒有辦法參考這個點就選出正確答案。
更好的判提點會是:
1. causing整句作果修飾前句的因會比non essential modifier修飾earth來得更合理。
2. 最後你應該會是C跟E在作比較，修飾簡潔的好壞問題比出來一定是C更為正確。

看解释是说 二十世纪的levels增长到 和 levels在二十世纪增长到有区别，(E) This choice alters the position of during the twentieth century" and thereby changing the meaning of the sentence. In this choice "during the twentieth century" modifies the carbon monoxide levels instead of describing when those levels "increased." This distorts the meaning by leaving open the possibility that twentieth century carbon monoxide levels "increased enough" during some other time period (e.g., the 21st century).
不过考试的时候应该没有这么多时间看这么仔细，请问你说的c修饰简洁表现在哪？后面的causing从句是一样的啊

跟二十世纪没啥关系。D项中Atmospheric carbon monoxide levels是什么鬼，和大气相关的一氧化碳水平？介词短语和形容词有时候可以互换，有时候不能互换，要揣摩介词短语的含义，这时候千万不要翻译，把atmospheric翻译成大气的你就怎么读都一样了，用英文尝试解释一下单词就容易明白。另外实名反对一下summer关于which的说法，当就近名词作为先行词明显不合理的时候，which也可能指代句子，在OG2020就增加了一个这个题来搞事，所以还是要用句意解题。

對 樓主有get到我的意思，除非你是ABC，不然不可能在實戰時短時間區分出來語意。
樓主你可以體會一下C跟E兩句前半段不同的地方，哪一個可以用更直接更少更有效率的單詞表達一樣的句意。
