怎么没人理呢？

哈哈。没人理是题目好多好难吧…………
1。……解释起来很麻烦啊。
2。主语research,谓语has revealed,it 指代research
3.句子里同样的代词指代同一事物，出现这种it一个做形式主语，一个做代词的肯定错。
4。“at its 1833 founding ”怎么读都是拗口，“1833号决议？”。而且1833是年份，语法上年份这样用肯定不对。（谁有反例）？这样排除AB
C 错误的嵌套for到when重句里，语法上错误。就算硬理解也是错误：成立的原因是这个DECISION。
D in deciding?肯定错。
E BY DECIDING 对   ，后面部分不如 to accept 好，但是不影响正确性。
