Final answer:
The dream farm in 'Of Mice and Men' is a fictional part of George and Lennie's dreams and there is no specific detail about its existence or sale price by an old couple in the novel.
Step-by-step explanation:
The dream farm that George and Lennie fantasize about in John Steinbeck's novel 'Of Mice and Men' is a fictional element of the story. The question seems to refer to a farm that an older couple is selling, potentially to be bought by characters harboring dreams of a better future. However, in 'Of Mice and Men', there is no specific mention of the actual existence of such a farm outside of George and Lennie's dreams, nor a price set by an old couple for sale.
The farm represents the personal dreams and aspirations for stability, freedom, and happiness that George and Lennie share. It symbolizes a paradise of sorts where they can live off the land and enjoy the fruits of their labors. The idea of the farm also acts as a motivating force for the characters within the novel.
