不知道这里A，B的解释是什么意思哈。。
但是区分ABC与DE是因为文中的结构是"Researchers agreed that ... but that ..."，平行对称的，可排除ABC。
而且A和B都有明显的错误：
A: "was or was not" 很罗嗦，表示“是或不是”时，应该用"whether"
B: 根据此的原始性质，"to determine" 比 " for determining"好
你参考一下哈，最好还是再看看书上类似题的解释哈

这里考的是平行，平行最重要的是看清楚谁和谁在平行，因为这里划线部分是一个完整的句子，所以肯定是和前面的that引导的完整句平行，所以应该是用that+完整句。排除了AB。
D改变了原意，把是否的意思去掉了，直接改成了陈述事实的语气。
E的need for doing是错的。

所以只能选C
