For questions 6 and 7, the story is very clear. Jupiter invited tortoise to his wedding and the reason why tortoise didn't go was because he was too lazy and chose to stay home. His laziness created a problem for him then: Jupiter punished tortoise by having him carry his house on his back. Tortoise began to regret not going to the wedding when he realized the other animals could move quickly and easily around, and he couldn't.
For question 8, the conflict is self vs self. Tortoise is not antagonized by nature, by a person, or by technology. He is antagonized by himself, his own laziness is his "enemy" and the cause of his problems. He is his biggest obstacle to overcome.
I would think that "insensitive" meant that his other girlfriends thought he didn't care, or he was a total idiot or soemthing. Just something like that. I hope this helped a little bit love!
