While I find the question slightly pointless, I have to say I'm more than a little surprised that so many got it wrong. The question made it perfectly clear that 1,2,3,4 wouldn't be correct.
The question did indeed make it clear that it wouldn't be 1,2,3,4. I couldn't work out by looking at it how it could give any other answer, so I ran it and got 1,2,3,4.
That's how I got it wrong, and I assume that most people will have done something similar. Therefore I'm surprised that so many people got it right! There must be more people still using unsupported versions than I'd have predicted.
