A Tale of Two Cities, writing homework help: A foil is a contrasting character who helps

A foil  is a contrasting character who helps to set off the traits of a major figure in a story. In Charles Dickens’ A Tale of Two Cities, for instance, Sydney Carton and Charles Darnay are foils, as are Madame Defarge and Miss Pross. Choose one of these pairs and discuss how their similarities help to emphasize their differences, and how the contrast between the two serves to advance the plot and bring out the author’s meaning in the novel.
