I believe the correct answer is alliteration
A. Lacks evidence or reasons.
Cisneros plays around with connotation and denotation with the word only by using the word in different ways. As in this example sentence, it says they are the only daughter, inferring that there is one female child, but they say they are only a daughter, inferring that they feel they can be nothing more than a daughter.
The correct answer is C. Analyze as it <em>best</em> replaces "carefully look over" in the sentence. Although the other answers are reasonable, it is the minor differences in denotations that make "Analyze" correct. It is not "Formulate" as it means to create something, rather it be an idea or physical object. "Differentiate" tends to mean more of a compare/contrast then the context clues imply here. Finally, "Calculate" generally means to solve something.
