Answer:
Sor Juana de la Cruz
Step-by-step explanation:
Just from reading the paragraph we couldn't give a definite answer, but we can infer some things. For example the paragraph uses the pronoun Ella (She), so we know it refers to a woman. This eliminates both Miguel de Cervantes and Gabriel García Lorca, since these are male names. Now, the question asks which of his compatriots Octavio Paz writes about. Octavio Paz is a Spanish name, so the compatriot most likely has a Spanish name, likely eliminating Gioconda Belli, which is an Italian name.
If you know about Spanish literature though, this is clearly about Sor Juana de la Cruz, a Mexican nun and poet.
