Step-by-step explanation:
In the story Antojos by Julia Alvarez, the poster of the Palmolive soap is a significant symbol. It represents the protagonist Yolanda's yearning for her Dominican heritage and her struggles with her identity while living in the United States. The advertisement slogan suggests a transformation or cleansing, which parallels Yolanda's desire to reconnect with her roots and her journey towards self-discovery.
