問題詳情：
A tradesman was leading a caravan(商隊) to another country to sell his goods. Along the way they came to the edge of a severe hot-sand desert. They learnt that during the daytime the sun heats up the fine sand until it’s as hot as charcoal, so no one can walk on it -- not even bullocks(小公牛) or camels! So the caravan leader hired a desert guide, one who could follow the stars, so they could travel only at night when the sand cools down. They began the dangerous night-time journey across the desert. A couple of nights later, after eating their evening meal, and waiting for the sand to cool, they started out again.
Later that night, the desert guide, who was driving the first cart, saw from the stars that they were getting close to the other side of the desert. He had also overeaten, so that when he relaxed, he fell asleep. Then the bullocks who, of course, couldn’t tell directions by reading the stars, gradually turned to the side and went in a big wide circle until they ended up at the same place they had started from! By then it was morning, and the people realized they were back at the same spot. They lost heart and began to cry about their condition. Since the desert crossing was supposed to be over by now, they had no more water and were afraid they would die of thirst. They even began to blame the caravan leader and the desert guide.
However, the leader himself didn’t lose courage. He began walking back and forth, trying to think out a plan. Remaining alert, out of the corner of his eye, he noticed a small clump of grass. He thought, "Without water, no plant could live in this desert." So he asked his fellow travelers to dig up the ground on that very spot. They dug and dug, and after a while they got down to a large stone. He got down into the hole, put his ear to the stone, and heard the sound of flowing water.
A spring was found. All the people were overjoyed. They drank and bathed and washed the animals and cooked their food and ate. Before they left, they raised a high flag so that other travelers could see the new spring in the middle of the hot-sand desert. Then they continued on safely to the end of their journey.
