How to ask a question to get a cardinal number answer
Neil Armstrong was the first man on the Moon.
I need to convert this into a question. If "Neil Armstrong" was the answer, the interrogative form would be
Who was the first man on the Moon?
How do you ask this as a question if "first" was the answer?
Another example would be
Abraham Lincoln was the 16th President of the United States
whence did Neil Armstrong land on the moon?
However, this question could not necessarily be answered "first".
