What type of argument emphasizes that an alternative course of action carries greater advantage than the proposed plan?

The correct answer focuses on the concept of "arguing comparative advantages," which is a strategy that assesses and highlights the benefits of one option over another. In this type of argument, the speaker or debater outlines how an alternative course of action offers significant advantages compared to the proposed plan. This approach is effective in debates as it not only critiques the proposed option but also presents a compelling case for why the alternative is more beneficial, making it easier for an audience to understand the practical implications of choosing one direction over another.

This method relies on comparing the outcomes of different choices, weighing the pros and cons, and showcasing the superior benefits of the alternative. It engages the audience in evaluating the options based on their merits and helps to facilitate a clearer discussion about which plan may lead to better results.

In contrast, the other options pertain to different methods of argumentation. "Argument from quantity" focuses on the number of supporters or instances in favor of a claim, while "argument from principle" is based on ethical or moral standards guiding the debate. "Argument from quality" emphasizes the characteristics or attributes of an item or idea. While these methods contribute to debate, none specifically underscore the direct comparison of advantages as effectively as arguing comparative advantages does.
