各位前輩好，因為本人之前英文打底的不太好，所以最近在看原文教科書的時後產生了一
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.出現的which是修飾reciprocal guaranties的關代嗎?
2.我會陷入逗號的迷霧之中，像這種逗號很多的句子不知道要如何拆解QQ
3.resemble those subscribed to這句每個單字都懂但不知道意思
4.翻譯成中文要怎麼翻比較順??
不好意思問題有點多，非常謝謝各位前輩！！
