Final answer:
Photographs in articles function to support text, evoke emotions, and provide context, which enhances the reader's understanding and connection to the content.
Step-by-step explanation:
The most likely reason an author includes a photograph in an article is to provide visual evidence that supports the text, to evoke an emotional response from the reader, or to give a clearer sense of the people, places, and events being discussed.
For example, in an article titled “Factory Tours,” the inclusion of a photograph of children working in difficult conditions at a factory serves to visually communicate the historical reality of the subject matter, backing up the written descriptions with a powerful image that may create a stronger empathetic connection between the reader and the content.
Similarly, the photograph of a tenement factory by Jacob A. Riis helps to give context and adds to the emotional weight of the article, allowing readers to better grasp the living and working conditions of the past.
