Answer:
The best revision of this phrase using the academic vocabulary would be "The protagonist of" Mericans, "Micaela, expresses that her grandmother is awful."
Step-by-step explanation:
Unlike many may think, academic language should not be boring, confusing, or obscure. On the contrary: the clearer the meaning of the text, the better for the reader. Thus, the academic language must pass a message in a formal and educated way, passing all the necessary information with the correct use of grammar and spelling, as it was done in: "The protagonist of" Mericans, "Micaela, expresses that her grandmother is awful."
