need some help here guys please. I wrote Do the begginer has water? but was marked wrong, why it not accepted?
Because in English you can't say it like that, so Duolingo got confused and marked you wrong.
The sentence has no context, so while it is a proper sentence, it makes little sense. Maybe this could be used for an athlete, or for a person working outside, where it would be important to stay hydrated. And someone who is just starting out might not remember to bring their own water.
