Answer:
2. De esta agua no beberé.
Step-by-step explanation:
The proverb says "Nunca digas de esta agua no beberé" and it can be translated into English in the following way:
"Never say I won't drink this water."
The proverb "Nunca digas de esta agua no beberé" means that you have to be careful what you say because if you say "never" it means you will never do that in your life. And it could happen that if you don't have water you will have to drink the water you say you wouldn't drink. That's why the proverb says "never say that..." because It is referring to what we shouldn't say.
