What is a key question in the attack on solvency?

The key question in the attack on solvency focuses on the feasibility and practicality of the affirmative plan being proposed. In this context, asking whether the affirmative plan is achievable directly addresses its solvency by evaluating if the plan can realistically be implemented and produce the intended outcomes. This question is critical because even a well-argued plan with significant benefits can fall short if it is not realistically attainable within the given constraints, such as resources, time, and political will.

While appealing to the public or considering the costs versus benefits are important aspects of a plan’s overall impact, they do not specifically target the plan's ability to be executed effectively. Similarly, questioning whether the problem can be solved with minimal changes is more about the nature of the solution rather than its implementability. Thus, focusing on the plan's achievability provides a clear framework to assess its legitimacy and strength in the debate.
