Here's why:
* Tone refers to the author's attitude towards the subject matter. It can be serious, humorous, cynical, optimistic, etc.
* Theme is the central idea or message explored in a work of literature.
While courage itself isn't a tone, the author's choice of tone can highlight the presence of courage in a story.
Examples:
* Serious tone: A story about a character facing a difficult decision with a serious tone might emphasize the weight of the situation and the inner struggle of the character, making their eventual act of courage all the more impactful.
* Inspiring tone: A story about overcoming adversity with an inspiring tone might use uplifting language and imagery to highlight the character's strength and bravery, inspiring the reader.
* Suspenseful tone: A story filled with suspense might focus on the character's fear and uncertainty, building tension and making their courageous actions even more thrilling.
Therefore, courage can be a powerful theme that the author can choose to convey through different tones depending on the desired effect.
