But first, do you see that wagon (马车) in the streets? Please ask the driver what is in his wagon.' John went out to the street and returned quickly, saying that the wagon was full of wheat (小麦). 'Where is the wheat going?' asked Mr.Seidman. Again John went out to the wagon. 'The wheat is to be taken to Brod,' he said. Then Mr.Seidan wished to know from where the wheat came and how much wheat there was in the wagon. Therefore, John made four trips in order to answer all the questions. Then Mr.Seidan called Joseph. 'Joseph,' he said, 'ask the driver what is in his wagon.' Joseph quickly ran out to the street and came back quickly. 'The driver comes from the town of Sinyava,' said Joseph, 'but the wheat comes from Svod, and he is taking it to Brod.
