OG12-sc-78，关于被修饰对象

还有在gmat中，

1  限制性定语从句只能用 that？
2 非限制性定语从家只能用 “ ，which/ who/ whose” 等等，也就是一定要用逗号隔开？
3 能够被分词合理替换的是 非限制性定语从句，限制性定语从句不行

如果有说的不对的请大家指正拍砖

搜过以前的帖子，可是发现木有人出现我的问题啊~~请大家帮忙看看
初一看题，我就把found in Puerto Rico in 。。作为修饰 sloth的定语了，但是看og的解释found in Puerto Rico in 是修饰fossils的，请问为什么found in Puerto Rico in 。不是就近修饰sloth呢？


谢谢大家帮忙回答~~

做语法，最好就是理解意思，如果found in Puerto Rico in 1991年修饰sloth，就变成了在1991年在Rico被发现的树懒，整个句子变成了在。。。发现的树懒的化石xxx，是不是曲解了作家的意思呢？


另外其他同楼上

我也觉得这里的found比较混乱，一般说的是v-ed过去分词修饰的是其紧跟的名词，但是好像也有发生跳跃性修饰的例子，就比如这个题目中就属于跳跃性修饰了，所以在判断这种修饰成分的时候还是得理解逻辑含义吧。
包括which的指代问题也是一样，什么时候跳跃指代什么时候不跳跃指代，个人现在感觉只能通过带入到句子中然后根据逻辑含义即which等后面的修饰性内容的意思来判断which指代的是哪个，然后看看这种指代是否犯了语法性错误，如果没有犯的话那么这个指代我们就认为应当是正确的。。。
