Also it should be pointed out that the "ask three times" system for framing a sermon is a common setup in Indian literature. I wouldn't take it too literally.
Retro is right. Either the monk is being a jerk, or more likely, he knows that the question you're asking isn't going to help you escape suffering. Try and respect his decision and reflect on what drives you to want the answer. Is it simply curiosity and distractive theorizing or is it applicable and beneficial instruction?
If you feel as though the question really is important, or if the question is something like, "Hey, what did you do with all the donations?" then it's best to push, but overall, I think "Sit and watch the breath" is all you really need to know
Gain and loss, status and disgrace,
censure and praise, pleasure and pain:
these conditions among human beings are inconstant,
impermanent, subject to change.
Knowing this, the wise person, mindful,
ponders these changing conditions.
Desirable things don’t charm the mind,
undesirable ones bring no resistance.
His welcoming and rebelling are scattered,
gone to their end,
do not exist.
