Hello. Can we enumerate entities belonging to different semantic categories together? For example:
1.The police seized 50 grenades and firearms;
2.We saw 9 monks and children in the temple;
3.There were 200 soldiers and horses on the hillside;
4.The police seized 20 guns and knives.
I asked this because some Englishmen said these are grammatical sentences but only ambiguous. And two Australian librarians have confirmed to me they often heard such sentences in the TV program: "The police seized 20 knives and firearms last night". I myself have also heard similar expressions. But I find it a bit strange. Can anyone help?
