What type of context is relevant and how can I put this in my answer?

Generally, context can be split up into different types such as biographical (anything about the author or poet's life which links to the text), historical (events at the time of the author's writing which may have influenced them to write about such themes, social (issues such as gender, race and class, such as widespread child poverty influencing Charles Dickens to write Oliver Twist or A Christmas Carol). In order to make sure your context is relevant, you would have to match it to a theme in a novel and you must embed this within your answer. Embedding means writing "the patriarchal society in Of Pride and Prejudice is heavily influenced by gender roles in the Elizabethan era" rather than writing "the Elizabethan era was an era where women did not have the same rights as men" because this would be to state the obvious, rather than making it specific to your question.
