Written like this “Someone’s mother has four sons North, West and South. What is the name of the fourth son. I see here it says the answer is Someone but “what is the name of the son.” Is a statement it has a period not a question mark and as far as the “someone’s mother has four sons” you could say Sherry is someone’s mother without the child’s name being someone so some people think the answer as the it is written would be That the forth son’s name is What . Which makes sense to me so does the answer change depending on if it ends with a period or a question mark ❓
