Below is a sentence from a university entrance exam in Japan:
(A) Without languages such societies could hardly exist, neither could have human beings nor languages existed.
I wonder why the author wrote as "
neither could have human beings nor languages existed", not "
neither could human beings nor languages have existed".
(B) Without languages such societies could hardly exist, neither could human beings nor languages have existed.
In my understanding and feeling, the above word order is standard.
1, Is the word order of Sentence (A) also acceptable?
2, What is the reason the author wrote as Sentence (A), not as Sentence (B)?
3, Do these sentences make any difference?
Thank you in advance.
