I confirm having tried Chat GPT - it is absolute junk.
While I don't know the answer to your puzzle, I asked Copilot Pro. It says this ...
✅ The Correct Olympian: Steve Cram
- Sport: Athletics (Middle-distance running)
- Olympic Silver:
- 🥈 Los Angeles 1984 – 1500m
- Other Major Silvers:
- 🥈 World Championships
- 🥈 Commonwealth Games
- 🥈 European Championships
While not all are Olympic medals, Steve Cram is often described as having “four major silvers” in elite competition, with
Los Angeles 1984 being the first.
🏢 Business Premises
Steve Cram is associated with:
- Cram Performance – a sports consultancy and coaching business
- Based in Northumberland, UK
So if someone is standing near a business premises in Northumberland and says “200m behind me is the driveway to the business premises of a former Olympian… who won a total of 4 silver medals… the first one at Los Angeles,” they’re almost certainly referring to
Steve Cram.
So now you can tell me, that's Copilot Pro is junk too I will guess.
