Final answer:
Homosexuality is a theme in Brokeback Mountain, while Pride and Prejudice explores societal expectations and conformity to heterosexual norms. Frankenstein and The Old Man and the Sea do not explicitly address homosexuality.
Step-by-step explanation:
In Pride and Prejudice by Jane Austen, homosexuality is not directly addressed as a theme. However, the novel explores societal expectations and the pressure to conform to heterosexual norms.
In Frankenstein by Mary Shelley, homosexuality is not a character trait explicitly discussed. The focus of the novel is on the pursuit of knowledge and the consequences of playing god.
In Brokeback Mountain by Annie Proulx, homosexuality is a central plot element. The story follows the forbidden relationship between two cowboys.
In The Old Man and the Sea by Ernest Hemingway, homosexuality is not a prominent element and does not serve as a setting.
