Emma question

I need some help with a questioni was given for uni as i dont know how to approach it- i need some ideas for how i would respond to this in terms of emma being a revolutionary novel

i as well need to consider the quote within my response:
“Very little white satin, very few lace veils; a most pitiful business!” 333 (Volume III, Chapter XIX).Emma
