Answer: A) Elenita struggles to keep her identities separate.
Step-by-step explanation: in literature, a conflict is a struggle between opposite forces, usually between a character (the main character or a very important one) and himself (internal conflict), society or another character (external conflict). In the given passage from Judith Ortiz Cofer's "Gravity" we can see an example of an external conflict in the fact that Elenita can't invite her friends over to her apartment, but it reflects the internal conflict that Elenita struggles to keep her identities separate ("they would have suffered culture shock").
