What linguistic feature would I draw upon to explain this?

If i was writing an informative piece on a random topic and I wrote for instance "Ok, but how does CO2 get released? By burning fossil fuels." By asking a question to my intended audience and then answering it, I am not using a rhetorical question in my opinion which leads me to ask.. what would that language feature/strategy be?

Solution 1:

Hypophora:

Hypophora is a figure of speech in which a writer raises a question, and then immediately provides an answer to that question. (From https://literarydevices.net/hypophora/)

It Is used to generate curiosity in the listener/reader, rather like a medic running using water to induce urination.

See also anthypophora and antipophora, which Wikipedia lists as synonyms. All three are figures of speech in general- not only literary devices.
