GWD 21-19

Regardless of their form or function, all aerodynamically enhanced, curved objects made for throwing have been called boomerangs by non-Australians even since 1788, when Europeans saw Dharug-peaking men tossing “bumariny” in the area later known as Sydney.

E.      Non-Australians have called all aerodynamically enhanced, curved objects made for throwing boomerang ever since 1788, regardless of their form or function, from

这题C没有最后那个from是不是也对呢 ?

help

their指代不对吧！！！c中的their优先指代Australians

我也有这个疑问,如果c去掉from以后是否正确?

c中的regardless of their form or function,的their是否存在指代不清的歧意呢?

代词指代是不是不当作一个排除的手段阿

C. 简化一下句子，

Ever since 1788, non-Australians have called objects, from when ...

have called objects What-Name?  缺少宾补。句子结构不完整。

而且，改变了句子重心。原文主语是objects,  C. 改成了Europeans.

C.     Ever since 1788, non-Australians have called (all aerodynamically enhanced, curved) objects( made for throwing )boomerangs, regardless of their form or function, from

不缺宾补呀

还是想继续问 regardless of their form or function,是否会产生歧意

楼上说得对，我忽略了boomeranges, 原句不缺宾补。

regardless of thier form or function 是插入语，不明确的是their的指代。

另外，该句子改变了原文句子的重心。
