Read the excerpt from the hunger of memory by richard rodriguez.
i have taken caliban’s advice. i have stolen their books. i will have some run of this isle.

once upon a time, i was a “socially disadvantaged” child. an enchantedly happy child. mine was a childhood of intense family closeness. and extreme public alienation.

thirty years later i write this book as a middle-class american man. assimilated.
what is rodriguez's most likely purpose for including the allusion to caliban in this excerpt?

a. to show how he has gained an education outside the classroom

b. to show that he is interested in learning more about classic literature

c. to illustrate how devoted he is to classic literature

d. to illustrate his views about the power of education
