Answer and Explanation:
A. Dickens presents these children as miserable and sad beings. They have an uncomfortable appearance for Scrooge and for the reader who sees them with a tone of suffering and need. Dickens' idea was to represent the poor and how they are neglected by the humanity that keeps them in this precarious situation.
B. Children in "A christmas carrol" are portrayed in a similar way. Scrooge, for example, sees himself as a child. He realizes that he was not a happy and loved child. Throughout the book, the children who appear have the same feeling, less the children of his employee, who despite having immense difficulties and limitations, were happy, because they had love, affection and care.
