"You were not able to understand everything at ten years of age."
Translation:Voi nu puteați să înțelegeți tot la zece ani.
I've listened to the pronunciations from native speakers of both "ea" and "ia" on Forvo.com and I do not hear any difference between the way that natives pronounce these two words. Would you care to elaborate on how these words should be pronounced differently? Maybe you could share a link to a recording that you upload somewhere?
