Tone is the narrator’s or speaker’s attitude toward the subject, and it shapes how we understand a text. To identify it, look at word choice and the connotations those words carry, the imagery and sensory details the author uses, and the mood created by sentence length and structure—short, abrupt sentences can feel urgent or tense, while longer, flowing sentences can feel calm or reflective. Punctuation, rhythm, and any figurative language also signal tone. By gathering these clues, you can tell whether the author is serious, humorous, skeptical, hopeful, sarcastic, or something else, which helps you interpret the writer’s purpose and how the text is meant to affect the reader. Tone isn’t about temperature, it isn’t the same as genre, and you can identify it from the text itself.

Captions and graphs help understanding by providing visual support that ties directly to the main ideas and data in the text. A caption explains what an image, chart, or diagram shows and why it matters, helping you connect the visual to what you’re reading. Graphs turn numbers and relationships into a form your eyes can scan quickly, so you can see trends, comparisons, and changes without wading through lots of prose. Together, captions and graphs reinforce meaning, make complex information clearer, and give you quick access to important details. They aren’t meant to replace the written text, though; they supplement it. A graph doesn’t necessarily summarize the entire argument or narrative, and a caption isn’t a substitute for reading the full explanation. Good captions and well-designed visuals don’t distract—they clarify and support what the author is conveying.

When analyzing how a character changes, you want to trace where they begin, what moments push them to change, and how their beliefs or actions evolve as a result. The three elements to track are the initial traits that establish the starting point, the pivotal events that test or force growth, and the changes in behavior or perspective that show the actual development over the story. This combination gives you a clear arc from who the character is at the start to who they become by the end. Mood, setting, and conflict shape the atmosphere and drive the plot, but they aren’t the direct evidence of a character’s inner growth. Dialogue length, vocabulary, and pace reveal voice and style rather than a character’s transformation. Physical appearance, age, and gender are external attributes and may change for reasons unrelated to personal growth; what matters for development is how thoughts and actions shift in response to experiences.

The main idea being tested is how meaning is conveyed in language—semantics. Semantics studies how words and phrases carry meaning, how their senses connect to concepts, and how context can change interpretation, including denotation and connotation. The correct choice fits because it specifically focuses on meaning and interpretation of language. The other terms relate to different aspects of language. The lexicon is like a mental dictionary of words and their meanings, but the study of meaning itself is semantics. Phonology is about sound patterns and how speech sounds function in a language. Morphology looks at the internal structure of words and how they are formed with roots, prefixes, and suffixes.
