Final answer:
The author provides support for their argument by offering clear reasoning and substantiating it with evidence, while also considering counterclaims. Sufficient support is determined by the soundness of reasoning and the relevance and reliability of the evidence presented.
Step-by-step explanation:
The author supports their argument by providing reasoning and then backing up that reasoning with concrete evidence to substantiate their claims. For instance, when writing to support or oppose the removal of a Confederate general's statue, the author may include a clear viewpoint bolstered by evidence such as the historical context of why the statue was erected and how its removal could benefit the community today. Furthermore, the author might also address counterclaims to show a comprehensive understanding of the topic, indicating empathy for different perspectives and reinforcing their argument by explaining why the proposed action will still be beneficial.
To evaluate if an argument is supported sufficiently, we must assess whether the reasoning is logically sound and whether the evidence provided actually substantiates the claims made. A lack of adequate reasoning or reliance on fallacies, such as appealing to emotion or making irrelevant associations, can indicate a weaker argument. In contrast, well-supported arguments include reliable citations from other sources, directly connect evidence to claims, and consider counterarguments thoroughly.
