An utterance by which ”the speaker is testing whether a listener knows a piece of information by asking them to supply the information”. The speaker, normally the tutor, already knows the answer. They are often questions, but can be also requests: ”tell me how electricity flows through the circuit” [1][2]
Example (1):
-Explainer: [So tell me, what do you know about black holes?] --->Diagnostic query -Explainee: ["Well, I know they're created when stars, once they start growing, it doesn't, it can't expand anymore, so they collapse inward.] -Explainer: ['You got, pretty much, you got a very good idea about it...]
Example (2):
-Explainer: [So far, what do you know about black holes?] --->Diagnostic query -Explainee: ['I never knew beforehand how hard it was', 'to get actual data of the black holes itself,', "first of all, they're dark, and, like,", "they're so far away, it's almost impossible just", 'to get a good image of them.', 'They were discussing a project in', 'which multiple radio telescopes of some sort, like, are,', 'like, pinpointed all across, from Greenland', "to South America, and, like, and they're trying to", 'get an image of', 'the black hole in the center', 'of our galaxy because, as opposed', 'to just recording its impact', 'on the surrounding stars and planets.']
