How do u tell the difference between a central idea and a detail

Can someone me look back at "the chrysanthemums" and write down at least two specific moments where the ranch or garden setting you understand something about elisa, and then at least two specific moments where the road setting does the same. write a few sentences to describe what's happening in each moment and how the interplay of character and setting us understand this person.

Used for an event that has been completed before the present moment in time. simple past past perfect perfect progressive past perfect progressive

Which statement correctly analyzes how the passages work together to create a central idea?
