The correct answer is D. In the first excerpt, the author uses narrative techniques and figurative language, while in the second excerpt, the author includes facts to persuade.
The first excerpt describes a person, using literary techniques like a third-person narrator who is also omnipresent (he descirbes feelings that only the person described could know are being felt.)
The second excerpt, on the other hand, presents evidence and facts, like time tables (for two decades, three years ago, this year), figures (6,800 children, 90,000 children), and the evolution of an issue (the advancement throughout the years of the same problem.)
