"The snake drinks tea."
Translation:Con rắn uống nước trà.
Yes. It's more natural than "uống nước trà" (don't know if it supports by Duo though).
So, 'nước' is a classifier for liquids? Can it be used before any liquids or it's not common?
You can use it for beverage (maybe), but you can't use it with chemistry element :)))
Because the Mods like things happen like that, so they let the snake drink tea.
