Which of the following best describes the theme of the passage?
Correct Answer: C
Rationale: The correct answer is C: 'Objective.' The passage presents a factual account of Clara Barton's life events without showing bias or personal feelings. The text outlines significant milestones in Barton's life chronologically, from her birth to her contributions during and after the Civil War, culminating in her advocacy for the establishment of an American branch of the International Red Cross Organization. The passage does not exhibit a patronizing tone (choice A), as it does not talk down to Barton or belittle her achievements. It is also not skeptical (choice B), as it does not express doubt or disbelief in the information presented. Furthermore, the passage is not nostalgic (choice D), as it does not dwell on sentimental feelings or memories of the past. Therefore, 'Objective' is the most suitable description of the passage's theme.
