Advanced Placement (AP) English Language and Composition Practice Exam

The correct choice effectively illustrates tone in writing because tone is primarily conveyed through the author's choice of words, which can evoke specific emotions and attitudes in the reader. By utilizing particular diction—such as adjectives, verbs, and even adverbs—an author can establish a mood or perspective that reflects their stance, whether it be joyful, sarcastic, somber, or critical. This emotional resonance is what engages readers and shapes their understanding of the text's overall message.

In contrast, the grammatical structure of a sentence primarily relates to syntax and does not inherently convey the emotional undertone of a piece. While it can influence readability and flow, it does not directly reflect tone. The length of paragraphs can affect pacing and organization but likewise does not express tone in the way that word choice does. Finally, the number of characters in a text is more relevant to formatting or character development rather than conveying emotional nuances, thus making it irrelevant to the concept of tone.
