Final answer:
The quote from 'A Wrinkle in Time' suggests the theme that appearances can be deceiving, as it deals with the concept of sight in a world without eyes. In literature, themes are conveyed through motifs, character development, and are not always explicitly stated, requiring reader interpretation.
Step-by-step explanation:
To match the quote from Madeleine L'Engle's A Wrinkle in Time with the appropriate theme, we need to look into the thematic significance of the line "How can you explain sight on a world where no one has ever seen and where there is no need of eyes?" This statement alludes to the theme that appearances can be deceiving. It highlights the idea that understanding and communication often depend on shared experiences, which in a world void of sight would be comprehensively different.
Identifying themes in literature involves examining motifs and the evolution of characters throughout the story. Authors like Twain use literary elements, such as plot, imagery, and point of view, to convey themes implicitly. Often, the reader must infer the deeper meanings behind the text, which are not explicitly stated. In the process of analyzing, it's essential to keep the text's nuances in mind, allowing for various interpretations that enable readers to connect the themes to their personal experiences.
Themes are universally significant because they touch upon concerns relevant to all cultures and societies. These recurring ideas may reflect humanity's larger philosophical questions and how individual experiences can influence our perception of the world and others. The exploration of themes is a fundamental aspect of literature that both reflects and shapes our understanding of life.
