Uncompressed 1080 is already approaching the eyes resolution limit, when viewing it in a living room environment. 4K is close to the monitor usage limit.

The reason that 4K seems better is often down to bandwidth and colour depth.

There's zero benefit to an 8K TV. An 8K monitor might be useful, but is still well into the diminishing returns curve.

There's still some ground to be made up with colours and frame rates, but resolution is effectively maxed out already.

It depends on the hose and the flow rate. They can vary a lot.

Also, your not just clearing the stagnant water, but also anything that was growing in it.

I'm guessing that the computer randomises the answer list, to limit cheating. The rest writer was likely cursing it too.
