Maybe they fixed it, because I have audio. You can hover over your name and select Settings from the popup to change if you accidentally turned off your audio. I did it on purpose before, then later I wanted it back.
so if duo gave me the english, i could translate it as "eu gosto desse biscoito" or "eu gosto daquele biscoito" since there is no context to clue me in as to the location of the biscoito? Am i understanding this correctly?
'Daquilo' is not masculine; it is neuter. It is used only when there isn't a noun for it to agree with. If there is a noun, then you use 'daquele' with a masculine noun or 'daquela' to agree with a feminine noun.
