What an odd set of options. I'll choose "Heated Swimming Pools", because that is by far the least consequential.
An advanced society with swimming pools, yet somehow the idea of heating a swimming pool has never occurred to anyone, should be a SCP.

What's SCP? The website looks insane.
I wonder if we also, by inference, would not have the technology to boil food. Would this be a world without soup?

Well... One way to write the SCP would be to introduce a bunch of cannibals who discovered heated swimming pools while attempting to cook someone alive.
