In the food lesson, using the singular strawberry was marked as incorrect because strawberries are countable, and the explanation was that because of this no one would really refer to a single strawberry but rather strawberries. The question at that time was "Spiser de jordbaer?", which I was asked to translate. When I responded, "Do they eat strawberry?" it was marked wrong and should have been plural. Why is not now singular? This seems a bit inconsistent, as the same logic behind the previous question should apply here, right? How would one say "She is eating the strawberries." ?
