Read the passage and answer the question

Here in the station, it is in no way different save that the city is busy in its snow. But the old men cling to their seats as though they were symbolic and could not be given up. Now and then they sleep, their grey old heads resting with painful awkwardnesson the backs of the benches. Also, they are not at rest. For an hour, they may sleep in thegasping exhaustion of the ill-nourished and aged, who have to walk in the night. Then, a policeman comes by on his round and nudges them upright. ''You can't sleep here'', he growls. A strange ritual then begins. An old man is difficult to wake. One man after a slight lurch does not move at all, he sleeps on steadily. Once in a while, one of the sleepers will not wake; he will have had his wish to die in the greatdroning centre of thehive rather than in some loney room fulfilled.
