"Jullie hebben de pasta en het water."
Translation:You have the pasta and the water.
Because it's de pasta and het water, so it's referring to specific pasta and water. Else it would have been jullie hebben pasta en water.
Why they write de pasta en het water whats the deference between het and de is there specific role for them
There is no rule when using het or de. You need to memorize which noun gets which article "het ei" is always het. "De vis" is always de. A couple of tips that might help. 1. 75% of nouns use "de" and 25% use "het" so focus on memorising "het" words and the rest will be "de" 2. ALL plurals will use "de" Example: The girl - "het meisje" (singular). The girls - "de meisjes" (plural). Hope that's helpful. It was for me.
2nd person singular: Je/jij/u hebt de pasta en het water. Plural: Jullie hebben de pasta en het water. The translation is the same "you have" vs "you are having" At least so far as I know (still a noob)
