What is the conclusion of the passage

A single short story can suggest a desired response from the reader. It is a difficult task, though, to create
a world within a single short story and then repeat this world again in other stories while maintaining a
consistent flow of ideas. Many authors prefer to use the same setting, indeed, often the same characters in
each story. Isabel Allende’s Diez Cuentos’ de Eva
Luna comes to mind. In these stories, Allende uses the small town of Agua Santa as the setting for the entire
collection.

Woman Hollering Creek is a collection of short stories by Sandra Cisneros. Rather than using the same
characters or setting throughout the collection, Cisneros takes a different approach to relating her stories to
one another. Much of the burden, in fact, is placed on
the reader, for the characters change each time, as does the setting.
Furthermore, while the characters are
largely Mexican American immigrant women, each character presents a distinct style and literary voice. What
these works have in common is more intuitive; mood, circumstance, time, tone, and imagery all play a role in
creating the world in which the stories take place

What does these refers to? Are they Sandra’s short stories or both of the writers ?
