Final answer:
The question contains a typo in the book title, blending 'Of Mice and Men' with another storyline. Without the correct title, a specific chapter ending cannot be provided. However, 'Of Mice and Men' does not have a happy ending centered around a character named Oliver.
Step-by-step explanation:
The question seems to be concerning the ending of a chapter in the novel Of Mice and Men by John Steinbeck. However, the title has been mistyped as 'Of Mice mad Men.' Assuming we are referring to Steinbeck's novel, without access to the text, I cannot provide the specific details of how Chapter 4 ends. The novel Of Mice and Men is known for its themes of friendship, dreams, and the harsh reality of life during the Great Depression, but it does not end happily as the reference information suggests, which seems to pertain to Charles Dickens' Oliver Twist. In Of Mice and Men, the ending is tragic and centers around the characters George and Lennie, rather than a character named Oliver. It is important to confirm the correct title of the book to provide an accurate answer.
