Final answer:
Gustave Flaubert's novels are best described as precisely descriptive, capturing the details of everyday life and societal pressures without romanticism or excessive sentiment.
Step-by-step explanation:
The realism of Gustave Flaubert's novels is best described as precisely descriptive. His work, including the famed novel Madame Bovary, is known for detailed rendering of settings, sophisticated character development, and a focus on the everyday lives of people. His realism sought to portray life as it was, capturing both the ordinary and the unpleasant aspects without romanticizing them. Unlike Emile Zola's naturalism, which often showed characters trapped by their circumstances, Flaubert's realism does not lean on determinism to the same extent but focuses on the characters' inner lives and societal pressures that lead to their actions.
