"Who likes celery?"
Translation:Siapa yang suka seledri?
I cannot give you a straight answer but i begin to feel the reason. Who likes celery? You are asking, you don't know, uncertain...etc
the same for : Which one is your son? Yang mana anak kamu?
Another example : who died? siapa yang meninggal?
This is my feeling and strange enough , i was right.
