Answer:
The organizational structure of the passage supports the author's purpose by:
B. To persuade the reader that the cafeteria should add a burrito bar, the author uses a proposition and support structure that explains the advantages a burrito bar would bring.
Explanation:
The reasons behind this answer are: first of all, the author wants to persuade the reader to accept and support the idea of having a burrito bar. So, c is incorrect but the structure of the answer confirms it as it has grammar errors. Second, the author doesn't use contrast to fundament its opinion. Furthermore, it provides evidence of the benefits the burrito bar would have in the context. So, b is the correct option because that is the one providing arguments that support an idea, instead of contrast. Third, there is no contrasting elements in the text because the writer doesn't explain what are the cons of having a burrito bar.
