What makes the provided statement a good supporting evidence for the author's argument?

The statement is considered strong supporting evidence for the author's argument because it is directly relevant to the claim being made and effectively substantiates the argument presented. Good supporting evidence should reinforce the author's main point, providing clarity and justification for their position. In this case, the relationship between the evidence and the claim indicates that the writer has backed up their argument with information that directly aligns with the central theme or message, enhancing its credibility and persuasiveness.

While other choices mention aspects that could be interesting or beneficial in certain contexts, they do not specifically affirm the direct connection needed to solidify the author's argument as effectively as the correct answer does. Thus, the relevance and the ability to substantiate the claim make it a strong choice for supporting the author's position.
