I previously thought the bold part is the same as というのか until I have been told
it is a causal version of というのですか today. So is there any difference between
というのか and というのですか?




~~ というのですか means something like "'are you saying?' or 'so you're saying'. It's
certainly a rhetorical question, not a real one. This form is often in
response to someone who has provided surprising information, but it can also
be used when realizing something for yourself."

~~というのか is more about rephrasing what has been told before, something like "I
said this, but it indeed means that", "or how should I say it". It is used to
nuance what you just said. it is similar to と言うより
