麻烦帮忙解析一个英语长难句，越详细越好，谢谢~

Three years of research at an abandoned coal mine in Argonne, Illinois, have resulted in findings that scientists believe can help reclaim thousands of mine disposal sites that scar the coal-rich regions of the United States.
详细分析一下整个句子主谓宾及其他成分，以及从句内的主谓宾及其他成分。

尤其是后半句中的 believe can help reclaim这四个连续的动词，是以什么语法结构或动词的搭配组合在一起的。
我只知道help的基本用法是
help sb. to do

help sb. do

can't help doing

help to do

没见过help后面直接接动词的

Answer 1

句子的主体是：research have resulted in findings

1， Three years of research at an abandoned coal mine in Argonne, Illinois中Three years of是定语修饰research
at an abandoned coal mine in Argonne, Illinoiss是状语，也是修饰research。
2， have resulted in findings that(1) scientists believe can help reclaim thousands of mine disposal sites that(2) scar the coal-rich regions of the United States.是个双重定语从句

that(1)是引出scientists believe can help reclaim thousands of mine disposal sites，来修饰findings 这个名词，这个句子还原之后是scientists believe that(1)/findings can help reclaim thousands of mine disposal sites.因为做定语从句要把that(1)提前，这里的that(1)也可以换成which来引导定语从句。

believe can help reclaim不是连续四个动词，而是believe (findings) can help reclaim，只是把findings换成引导词that(1)提前了。

这里的help reclaim 相当于helo to reclaim，只是把to 省略了，两种用法都是对的。翻译成：有助于...

that(2)引出第二个定语从句that scar the coal-rich regions of the United States，用来修饰mine disposal sites这个名词短语。

我猜help后面可能省略了宾语
