In the English answer the ONLY things that are definitely red are the tomatoes. As the strawberries might not be. Therefore ‘red tomatoes and red strawberries’ should be acceptable. Or ‘tomatoes and red strawberries’? Can Indonesian speakers clarify for me if in the Indonesian example only the strawberries are definitely red or the merah at the end automatically means all things in the sentence must be red?
I think the given translation, and all the alternate answers, are adequate. It's not the exact translation, but it reflects the same ambiguity in both languages! In Indonesian, since modifiers go at the end, we can't be certain if merah describes only stroberi or if it describes both stroberi and tomat. Similarly, since modifiers in English go in front, it's uncertain if red describes only tomatoes or both tomatoes and strawberries. It's okay that you don't know what exactly merah is describing, that's an inherent ambiguity in the language that will depend on context!
