The old challenge prompt was great because, in describing the issue, what happened, how you tackled it, evolved, and the good you now do, you could somewhat follow the true order in which it all occurred. (Not all details are needed.)
You don’t have to answer any prompt exactly as written. There’s no teacher to grade you and subtract a point or two for not answering the specific question. Just try to understand what adcoms want to see in you, learn about you.
See how you can make one of the prompts work for you. Relax into it.
