In my grammar textbook, under the title “Questions”, it’s stated that we don’t use “do, does, did” at the beginning of a questioning sentence, when the subject is “who/what etc.” For example:
“Somebody called Donald.”
So if we want to ask about the above statement the correct way of asking is:
“Who called Donald?"
Not: “Who did call Donald.”
So in this way if I wanted to make a questioning sentence from the following sentence:
“About one-hundred people came to the ceremony.”
I would have to ask:
“How many people came to the ceremony?”
But it sounds unnatural to me. I think the correct way is:
“How many people did come to the ceremony?”
Which one is correct?
