The statement by the New York Times is subjective because it reflects the reporter's interpretation and personal opinion about Yatman's physical state and emotional experience during the ride. The phrase "plainly showed the effects of the terrible strain in her countenance" suggests a judgment about her appearance and what it signifies. Other observers might have different interpretations of her expression; for example, someone might view her expression as one of determination rather than pain. This highlights the inherent subjectivity of the reporter's observation. Thus, the most fitting response is:
Someone else might think that Yatman’s expression was one of determination.
