So what's the answer? I looked at it for a bit, but I got stuck working out how all three promotions can have happened with so few captures, as well as getting the other pawns into position.

Something is fishy in this position. If a1 really is in the lower left corner, then how in h*ell did the black bishop enter the a1-square? This is not a valid position, viewed from this angle.

Let's flip the position, and then we go from there.

It must have been a promotion for it to be legal.

This is of course the only valid answer. Since black is in check white must have moved. Since white can't have moved the Queen it must have moved the Knight (the bishop would have checked before).

So wht about promotion adn legal moves?

Wait a minute ... Ne3 is not the only valid answer. There is also the possibility of Rg1+ [discovered check].

How did the rook get to g4? The king could not have gotten where it is with the rook on g4.

I don't think Ne3 is even a valid answer i think Nxe3 is the only valid answer but it is up to somebody with a more clever mind than mine to decide what was captured.

Getting the King to where it is is pretty difficult whether you put an N or R on g4.

Yes, but the rook on g4 would be blocking both entries for the king while the knight on g4 would be creating a possible entry for the king.
