Відповідь:

A train came to a small station, and a passenger peered out of the window of a train carriage, spotting a woman selling cakes. The man had skipped breakfast that morning and felt hungry, desiring a cake. However, the woman was standing quite far from the carriage. Afraid of missing the train, the man didn't want to go and buy a cake himself. He noticed a boy walking along the platform near the carriage, so he called out to the boy and asked, "How much does a cake cost?" The boy replied, "Threepence, sir." The man gave him a sixpence and instructed, "Bring me a cake, and with the other threepence, buy a cake for yourself." The boy took the money and went to the woman. After a few minutes, the boy returned, eating a cake. He gave the man threepence as change and said, "The woman had only one cake, sir."
