Final answer:
Captain Nemo changes in his attitude towards humanity and in his willingness to share his knowledge and experiences.
Step-by-step explanation:
Two instances that showed how Captain Nemo changed throughout the course of the novel '20,000 Leagues Under the Sea' by Jules Verne are:
- In the beginning, Captain Nemo was a mysterious and aloof character who seemed to have an unwavering hatred for humanity. However, as the novel progresses, he shows compassion and kindness towards the stranded survivors of a shipwreck, including the protagonist. This change in behavior suggests a softening of his heart and a growing empathy towards his fellow humans.
- Another instance that demonstrates Captain Nemo's change is when he allows the protagonist to explore the underwater world in his submarine, the Nautilus. Previously, Nemo had been strict about keeping his secrets and not allowing anyone to roam freely on his vessel. This act of trust and openness indicates a shift in Nemo's attitude towards sharing his knowledge and experiences with others.
