The correct answer to this question is C. Both text types use rhetorical techniques to support a particular viewpoint.
Step-by-step explanation:
Both argumentative and persuasive texts focus on supporting a specific point of view or position about a situation or issue. In most cases, this involves presenting evidence from reliable sources and using different rhetorical techniques such as rhetorical questions, analogies, persuasive appeals, among others that help the writer to show the main viewpoint is valid.
However, these two texts differ because, in argumentative texts, the author mentions and explains alternative viewpoints including opposing ones, while in persuasive texts, the only viewpoint that is explained is the one held by the author. Thus, one similarity or common aspect in both argumentative and persuasive texts is "Both text types use rhetorical techniques to support a particular viewpoint".
