Word for a yes/no question that's more to elicit a longer response

I'm looking for a word or idiomatic phrase to describe a question that can be answered by a "yes" or "no", but has a higher probability of getting a more open-ended response.

Indeed, without the "yes/no" requirement I'd describe what I'm looking for as an "open ended question", but the possibility to answer "yes/no" is key here.

An example question would be:

Do you feel remorse for your affiliations with the Nazi party?

Although it doesn't have to be a loaded question, just something which you are reasonably sure is going to get the responder talking beyond the y/n

Exam question came to my mind, just for fun though.

A typical exam question:

Is hell exothermic or endothermic?

How would we answer that? Should we just respond with exothermic or endothermic without a tedious justification, we simply wouldn't expect to get the mark.

Check out one possible open-ended answer for a laugh.

Your example looks like a leading question, where an alert answerer will argue with the framing of the question rather than simply giving a yes/no answer (and the lawyer who asked it will yell "Just answer yes or no, please!" while the opposing lawyer calls for an objection).
