I answered... Aucune d'entre elles n'est fiable

Question

"I answered... Aucune d'entre elles n'est fiable. The lesson led me to think Aucun/e & Aucun/e d'entre eux/elles were interchangeable expressions to say some/some of them. Why was my expression marked incorrect? Can you help clarify this for me?" Thank you.

Hi Jameson, 
This is why I was asking for the full context. 
In the examples taken from the lesson -
Aucune de tes robes ne me va 
Aucun de ses livres n'est intéressant 
You cannot use 'aucun d'entre elles, aucun d'entre eux' , as it is the first reference to the object in question.
Hope this helps!

Hi Michael,
I will need the full context as to what the 'none of them' refer to, in order to answer your question...

Hi Michael,I came away from the lesson with the same take away. "The lesson led me to think Aucun/e  & Aucun/e d'entre eux/elles were interchangeable expressions" .... to say NONE  of them.I am thinking that  Cecile could not  clearly answer your question without knowing if the antecedent(implied) in your "them" was feminine;  or masculine  which would have dictated..aucun-eux". And the adjective 'fiable' does not help in this case.However, I am hoping that Cecile can confirm aucun/e ne is completely interchangeable with aucun d'entre eux/aucune d'entre elles and that there is no grammar related exceptions.
