各位前辈好，因为本人之前英文打底的不太好，所以最近在看原文教科书的时后产生了一
些疑惑，段落如下：
Moreover,the parties seem content with no further safeguards than their own re
ciprocal guaranties which, in substance, resemble those subscribed to, mostly
unilaterally, by the recipient State in the other research-and-power bilateral
s.
1.出现的which是修饰reciprocal guaranties的关代吗?
2.我会陷入逗号的迷雾之中，像这种逗号很多的句子不知道要如何拆解QQ
3.resemble those subscribed to这句每个单字都懂但不知道意思
4.翻译成中文要怎么翻比较顺??
不好意思问题有点多，非常谢谢各位前辈！！
