When evaluating a text, which approach might consider its effectiveness in conveying its message?

The choice highlighting critical analysis is appropriate because this approach involves a deep examination of a text's themes, techniques, and overall impact on its audience. Critical analysis goes beyond mere description or structural breakdown; it evaluates how effectively the text conveys its intended message, exploring the nuances of its arguments, tone, and persuasive strategies.

In this context, while descriptive analysis focuses on summarizing and detailing the content, and structural analysis examines the framework and organization of the text, neither fully addresses the text's communicative effectiveness. Narrative analysis typically concentrates on the storytelling elements and character development but does not inherently assess the overall effectiveness in delivering the author's message, which is the core task of critical analysis. Therefore, critical analysis is the most fitting approach for evaluating how well a text communicates its message.
