How does the tone of the passage change with the last sentence?

The last sentence of the passage shifts the tone to a more depressive state by introducing somber themes or stark realities that may reflect loss, disappointment, or sadness. This change can often be marked by specific word choices or phrases that carry heavy emotional weight, leaving the reader with a sense of heaviness or concern. Such a shift can evoke feelings of empathy or melancholy, contrasting with the previous tone of the passage and deepening the overall impact of the narrative or argument being presented. The use of this last statement may also highlight a significant turning point in the text, underlining the gravity of the situation discussed, either by emphasizing struggles, consequences, or the darker aspects of human experience. This effectively creates a poignant ending that resonates emotionally with the audience.
