Respuesta :
We can select the correct answer among the multiple-choices. The author doesn't insult the readers because there is not any valid evidence to prove it. The same applies to the second option. We don't know that the narrator is knowledgeable or not - we need extra information to confirm that. The excerpt is just one sentence and it is clearly defined that there is nothing complicated. The only correct and suitable option is the last one since the answer is closer to understand. The correct answer is D.
