A
This weekend，Bob and his friends went to a mountain. When they got there，they put up their tents and then rode their horses to the forest to see how the trees were growing.
In the afternoon，when they were going back，it started to snow. Ten minutes later，they couldn't find the road. Bob knew there were two roads. One road was to the camp，and the other was to his house. But all was white snow. Everything was the same. How could he and his friends go back to the camp?
Soon Bob had an idea. Maybe the horses could help them. They can let the horses take them back! But what would happen if the horses took the road to his house? That was going to be a long trip.
It was getting late. They rode on and on. At last the horses stopped. Where were they? No one could tell. Bob looked around. What was that under the tree? It was one of their tents!
