How do I elabrate on a qoute for an Essay thing?

Basically what it means is to explain what the quote means. To give examples. Like an example i'd use though i deal mostly with চলচ্চিত্র in my উদ্ধৃতি and odds are আপনি probably haven't seen this movie but, i'd use Sam from the Gary Cooper movie Good Sam as an example. Sam was selfless in every aspect of the world he had broken his back for someone before. He sacrificed his wife's dream house to help a friend. He would be someone the quote could easily represent.
