"The women eat rice."
Translation:Kvinderne spiser ris.
No, that is not possible, since "det" is neutral singular (one thing) whereas "kvinder" is common plural (more persons) - these two words are simply incompatible in the language. I think "De kvinder spiser ris" would be possible and would mean "Those (particular) women (and not any other) are eating rice." But that is too complex for now, just stick to what's in the lesson: learn that "Kvinderne" means "the women".
