英语翻译
例句：But even more important,it was the farthest that scientists had been able to
look into the past,for what they were
seeing were the patterns and structures that existed 15 billion yeays ago.
1）But even more important?是状语从句吗?如果是,是什么类型的状从?
2）had been able to如果换成was able to 会如何?有何区别?

1,当然不是状从了,状语从句都这么叫了,那必然是一个句子啊,是句子都有主语和谓语啊（当然省略主语的祈使句除外）这个短语也就相当于一个状语吧
2,主句it was the farthest表明从句中要使用过去的某种事态,由句意可知科学家是从过去到现在一直在研究,应该用完成时态
