1. What did the king say to hear the first man’s lie?

2. What did the king say after hearing the first man’s lie?

3. What did the king say so that he could hear the first man’s lie?
------------------------------------
Does #1 mean #2 or #3?

1 and 3 mean the same thing. It would be better to say, "What did the king say that caused (or prompted) the first man to lie?" 1 and 3 ask what the king said BEFORE the first man lied", not after he lied.

Pay no attention to nader.
