Directions: Read the following passage and answer the question that follows.

PassageOn the afternoon of the following day a wagon stopped before a Belgian Refugee Camp in Holland. Slowly and stiffly a small boy slid to the ground. He had been picked up just over the border by a friendly farmer and driven to camp. He was dirty, untidy and footsore. Very kindly the ladies' committee received him. He was placed at a table and a bowl of hot soup was set before him. He ate awkwardly with his left hand. His right hand held something beneath his coat. The women tried to get his story, but he remained strangely silent. He seemed to be examining to faces of the women. Not for an hour, not until there was a faint stirring in his coat, did he disclose his burden. Then going to her whom he had chosen as most to be trusted, he opened his coat. In a dirty towel lay a naked, miserably thin, three-day-old baby. The woman at once took the tiny bundle lovingly. It was only then that boy relaxed and allowed himself to be taken to bed.

How did he reach the Belgian Refugee Camp?
