Final answer:
The phrases 'What glory would attend the discovery' and 'Render man invulnerable' in Mary Shelley's Frankenstein emphasize Victor's pride, capturing his ambition for glory over wealth and his wish to defy natural mortality.
Step-by-step explanation:
The words in the text from Mary Shelley's Frankenstein that help develop the theme of pride are "What glory would attend the discovery" and "Render man invulnerable." These phrases reflect Victor Frankenstein's tremendous pride and ambition. He is not primarily motivated by wealth but by the immense glory he anticipates receiving from making a significant scientific breakthrough, one that could potentially make humans immune to natural causes of death. This high regard for personal glory and the desire to conquer nature's limitations are central to the novel's exploration of excessive pride.
