Ah, as Randall suspected - the boat was nowhere near large enough to take everything over in one trip. Hey, wait a tick - the outlining and strutcture of this puzzle seemed really familar, now he thought of it. Yeah, it seemed almost exactly like the 'three wolves and three chicks puzzle' he'd told Hersh yonks ago when they first met, only this puzzle was dealing with humans HAVING to pilot the boat. Yet, the total number of things you had to ferry was the same.
"I know a puzzle really similar to this, actually - with the same amount of 'total things you gotta ferry', so I reckon it works pretty much almost the same way! Is the smallest amount of moves you can take...eleven, by any chance? If you want me ta explain my answer, I can do that too, but hey, this answer could be totally wrong.
I got a good feeling about this answer, though! No risk, no glory, so I'm going with my gut on it!"
A pause, before Randall took a deep breath in.
"Let's see, just in case ya want me to explain - on the first ferrying, the farmer and their vegetables go over. Since the traveller is left with the wolf, it's not 'alone' and therefore can't eat the sheep and cow. The farmer leaves the veggies on the other side and goes back alone. Then, the farmer takes the sheep over with him. Seeing as he's technically 'with' the sheep when he sits on the boat while it goes ashore, it won't eat the veggies.
He takes the veggies back with him, then. Then, the traveller finally gets a turn at going across, with the cow. Since the farmer stays behind with the veggies, they won't get nicked, and the wolf still isn't alone. The traveller leaves the cow on the other side with fluffy sheepy and goes back alone. Then, the farmer and the traveller go onto the ship!
Seeing as wolves have no interest in veggies, it's safe to leave them with the wolf while the traveller and farmer go across. The traveller gets off at the other side where the sheepy and cow are and the farmer goes back alone.
Then, the farmer takes the wolf across! As before, when the wolf is dropped off, he won't be alone, and therefore cannot eat any of the animals. The farmer goes back alone to pick up the veggies, and then take them back with him on the final crossing of the river!
It can be tricky, but if you consider some animals can go across or be left without eating or harming anything, it's a possible answer! So am I right this time, eh?"
