did not find any problem (hope EVEN is EVER). The opening modifier could modify objects. The non-underlined clause 'when..' modifies 1788. It is clear that OBJECTS have been called BOOMERANGS

THEIR does not match with ANY

Even though 'EVEN SINCE' appears better placed (but it creates problem with the non-underlined modifier - its not clear what does 'WHEN....' modifies).

Secondly, its not clear what objects are called. This is bcoz 'throwing boomerangs' appears part of the same prepositional phrase

Moreover, use of ANY changes the original meaning of the sentence (ALL OBJECTS are called BOOMERANGS; while this sentence ANY OBJECT are called BOOMERANG). Grammatically I did not find any issue though

Secondly, ALL & BOOMERANG (singular) donot match

IMO A

OA is AI'm still trying to understand why option B is not correct. Can anyone help?

I hope im not necroing an old topic but I think it has to do with SV agreement as above person mentioned. I had trouble with this one too and just kinda stared at them for a little and then it made sense. Check out two examples below (capslock/underline used to emphasize) hope it helps:



A. Regardless of THEIR form or function, ALL aerodynamically enhanced, curved OBJECTS
made for throwing have been called BOOMERANGS by non-Australians even since 1788,

sounds ok right? ok check out B

B. Regardless of THEIR form or function, ANY aerodynamically enhanced, curved OBJECT
made for throwing has been called A BOOMERANG by non-Australians even since 1788,

but B. looks ok too, right? what if I made one change from THEIR to ITS, then I believe B would be correct, but in its written form B is not correct.

B. Regardless of ITS form or function, ANY aerodynamically enhanced, curved object
made for throwing has been called A BOOMERANG by non-Australians even since 1788,


So because B has THEIR instead of ITS it is not correct, therefore A is correct. Hope it helps.
