Check out the lowdown on http://www.skoool.ie click here. They quickly summerise the section giving you key notes that will get you started (click on the link for cultural context for individual texts)
cultural context: write a paragraph on points such as how the cultural context influenced the outcome of the plots, shaped the lives of the characters, how the authors created unique worlds for the reader to experience, how the narrative structure – beginnings, key moments, endings etc – reveals the world of the text, how things like religion, class structure, symbols of authority (e.g police) add to our knowledge of the worlds of the texts.
Cultural context = attitudes, values, roles, rituals of the characters, structures of the worlds of the texts etc. What's normal in these worlds?
