Which sentence uses third person?

The sentence "She is reading a book" uses the third person because it refers to a subject that is neither the speaker nor the listener. In this case, the subject "she" indicates that the action is being performed by someone else. Third person pronouns include "he," "she," "it," and "they," and they are used to talk about someone or something other than the person speaking or listening.

In contrast, the other options use first person or second person perspectives. For example, "I like snow" uses the first person ("I"), referring directly to the speaker. Similarly, "We went to the park" also utilizes the first person, as "we" includes the speaker along with others. The first choice, "He had hamburger for lunch," does exemplify third person; however, it was not selected as the answer. The focal choice distinctly conveys a third person action performed by "she." Thus, the sentence that was identified as using third person correctly portrays someone outside of the interaction between the speaker and listener.
