To provide you with a valid inference about Jules Verne based on the excerpt from "How Nellie Bly Went Undercover," I would need to see the specific excerpt you're referring to. However, I can guide you on how to make inferences based on a typical excerpt discussing Bly and potentially Verne's influence on her work.
For example, if the excerpt mentions that Verne's adventurous novels inspired Bly's journey and her approach to journalism, you might infer that Jules Verne is considered a significant influence on the spirit of adventure and exploration in literature.
If you can provide the specific excerpt or more details, I'd be happy to help you make a more precise inference!
