Don't get me wrong, I'm not correcting a native speaker here - I'm just asking: To differentiate between Elles and Elle in this situation, would it be possible (not manditory, mind) to make a liaison with the t in posent and une? I mean, I agree that there's nothing in the actual audio to suggest it's either elle or elles but is this a way you could make sure your fellow interlocutor knew which you meant? Thanks.
Thank you, Nicholas Ashley for a very clear explanation.
I remember when (to say) 'to pose a question' was quite an everyday expression. It started to veer towards asking someone something that would require quite a bit of thought. Compilers now 'pose questions' for crosswords, etc. It is such a pretty verb that if we all started to use it we could possibly rescue it from increasing obscurity,- or find ourselves on the receiving end of some very puzzled looks. No apology for the pun!
