Answer: The strange case of Dr Jekyll mad mr Hyde.
Explanation: The story begins with Utterson and Enfield who were taking their regular walk on Sunday. As these two walked down a street, Mr. Enfield saw an abandoned building which reminded him of an odd story. He narrates the story to his cousin, Mr. Utterson. He said that he had witnessed a man trample over a young girl because she mistakenly ran into him. After their conversation, Mr. Utterson proceeds home. In his study, he found a will of Dr. Jekyll, his friend. Mr Utterson was bothered by the fact that his friend’s will is in favor of a stranger named Mr. Edward Hyde. He asked Dr. Lanyon, their mutual friend, if he knew who Edward Hyde was. Unfortunately, Dr. Lanyon complained that he had not heard anything about Hyde and he had cut ties with Dr. Jekyll because they had a science based disagreement.
The correct answer is Buck’s love for Thornton. There is bet placed about Buck’s strength, stating that he will not be able to pull a thousand pound sled. The amount is huge: 1600 dollars. Buck is able to do it and win the large amount for John Thornton. Although as a dog he really does not even know what is going on, his instinct tells him that accomplishing this task will please Thornton and because he loves him that makes him happy. This increases their bonding and loyalty to each other.
