a) To live without having to work
Step-by-step explanation:
The two friends, George and the half witted Lennie here are fantasizing abut living a life in which they do not have to work and have plenty in their lives.
This fantasy reveals that they are tired of going around town finding work and then getting scraps to eat, the vagabond life has taken a toll on them and they want to settle down in one place where they will have plenty to eat and no worries about food without having to work for it all the time.
