Final answer:
In the story "The Sneetches" by Dr. Seuss, the star-bellied sneetches initially excluded those with no stars, but later accepted and included them when they could no longer distinguish themselves.
Step-by-step explanation:
In the story "The Sneetches" by Dr. Seuss, the star-bellied sneetches treated those with no stars differently.
Initially, they excluded the sneetches with no stars and considered them inferior. However, when Sylvester McMonkey McBean introduced a machine that could add stars to their bellies, the star-bellied sneetches were no longer able to distinguish themselves from the others, and they started to accept and include the Sneetches without stars.
