Re: dump the rope into the valley
It's a smart-alec answer. The puzzle is supposed to mean you have, say, hundreds of feet of rope. The person who answered this way is assuming you have so much rope that you could throw it in the valley and it would make a pile that was 10 meters high for all 20 meters across, so you could walk across the pile of rope. It's a joke answer.
Seems to me you climb down the ladder to the floor of the little valley, carry the ladder the 20 meters, and then climb the ladder up the other side. Is that too obvious?

I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
