Conclusion:

Asking ChatGPT the same question multiple times results in a set of similar facts presented in a different way each time.  Not all the relevant facts may be revealed in each different version, so repeating a question is probably essential to learn all that is available.  As ChatGPT provides an almost instantaneous result, this strategy can be overwhelming. The alternative is to ask carefully crafted questions by including key words. This assumes some prior knowledge of the subject.

In this case ChatGPT provides a well-formed essay with an introduction and a conclusion that can be accepted in total or rejected in favour of the next iteration.  

I also asked ChatGPT to write short stories, about two of our grandchildren at their request, based on very brief parameters (suburb; name; schoolboy/ schoolgirl; and age - in one case only). In each case the first attempt was an inappropriate match to the particular child (hair colour, interests) but by simply refreshing (taking 25 seconds each time) I soon accepted a very nice little (1000 word) short story for each.

The stories are descriptive and lack character development; concerning a key event in their life (presumably randomly chosen); but derive an outcome (a moral) and are quite interesting and readable.

On Australia Day, I asked ChatGPT about the date. The result was suitably bland and middle-of-the-road that it might have been written for a government brochure to recent migrants. See here...

While the neural network algorithm behind ChatGPT assembles well-used tropes and cliches, it does this in a structured way, grammatically and well, with exceptional speed.  Hack Journalists beware, your job is in jeopardy.
