Questions 1 to 5 are based on the following passage：

　　（79）John had bought a packet of cigarettes just before we caught the train and he offered me one as we settled ourselves in our compartment. We were on our way back from a camping holiday；we had lived rough for over a fortnight and even a cigarette was a luxury at that moment.

　　I felt in my pocket for a box of matches，but could not find any.

　　“I haven't got any either，” said John.

　　Sitting opposite to us was a man whose face was hidden by a newspaper.

　　“Excuse me，sir，”said John，leaning across. “Could you give me a light，please？”

　　The newspaper was lowered to reveal a rather elderly man with a stern face.

　　“This is a no smoking compartment，”the man said. He indicated the notice near the window. We apologized and put away our unlit cigarettes.

　　（80）The man went on，in a rather more kindly way，to warn us against the dangers of smoking.

　　“I speak as a doctor，”he concluded，and after that he went back to reading his newspaper.

　　When he got out a few stations later，he left his newspaper behind him. We picked it up，eager to find out what had happened while we were on holiday.

　　“Just look at this，”remarked John，pointing to a photograph. “it's the man who was sitting opposite us.” Underneath the photograph was an account of a lunatic （精神病者）who had recently escaped. It appeared that he liked to pretend to be a doctor.
