Answer:
A critic cannot use a single approach to evaluate the work of literature because literary works are complex and multifaceted. Different literary works have different styles, themes, contexts, and historical backgrounds. Therefore, a critic must employ various methods and approaches to fully understand and evaluate a work of literature.
For instance, a critic might use a historical approach to evaluate a literary work by examining its context and historical significance. They might also use a formalist approach to analyze the structure, style, and language of the work. Alternatively, they could use a reader-response approach to examine the ways in which readers interpret and engage with the work.
Furthermore, literary works often explore complex ideas and themes that require different lenses of analysis. A single approach may not be sufficient to fully evaluate the work's complexities and nuances. Therefore, it is essential for a critic to use a combination of approaches and methods to provide a comprehensive evaluation of a literary work.
