Metaphor , The children 'Ignorance' and 'Want' are used to represent all the poor children in society: 'They were a boy and girl. Yellow, meagre, ragged, scowling, wolfish'.The children under the Ghost of Christmas Present's cloak are a metaphor showing the effects of greed and miserliness.The reader, like Scrooge, feels pity for these 'ragged' children and this extends to a sense of responsibility for all the poor and homeless children in society.
