What does completeness refer to in the context of evaluating an author's argument?

Completeness in evaluating an author's argument focuses on whether the argument addresses all relevant aspects of the topic at hand. This means assessing if the author has considered various viewpoints, evidence, and implications related to the issue. A complete argument should not overlook significant points that may influence the reader's understanding or acceptance of the argument, and it should sufficiently explore counterarguments or alternative perspectives.

In this context, completeness ensures that the argument is well-rounded and thoroughly developed, providing a clearer and more convincing rationale for the author's position. It helps the audience gauge the strength of the argument based on the depth of information and perspectives presented.

The other options, while relevant in their own contexts, do not directly pertain to the concept of completeness. Emotional appeal relates to how effectively the argument connects with the audience on a personal level. The length of the argument speaks to its brevity or elaborateness but does not inherently impact the completeness. The structure deals with the organization and presentation of the argument, which is crucial for clarity but does not necessarily indicate whether all aspects of the topic have been covered.
