Which term refers to a person or thing in expository reading comprehension?

In the context of expository reading comprehension, the correct term to describe a person or thing is "object." In this context, "object" refers to the specific elements, individuals, or items being discussed within a text or a narrative. For instance, when reading a passage that explains a concept, the key components or subjects mentioned that are integral to the understanding of that concept would be classified as objects.

Expository texts aim to inform or explain, often presenting various objects that the reader needs to understand to fully grasp the material. By recognizing these objects, readers can better interpret the relationships and information being conveyed in the text.

Other terms like subject, entity, and topic do have relevant uses in reading comprehension but are not as precise in describing the role of a specific person or thing within an expository text. The subject generally refers to the main focus or theme being discussed, the entity is a broader term that may encompass groups or characters, and the topic usually denotes the overarching theme or idea rather than pinpointing an individual object for clarity in comprehension.
