Question

In which instance would it be best to include images and descriptive captions?

To compare opposing ideas related to the topic
To develop a main point without additional argument
To give a break to those who might be tired of reading
To show an important or unclear idea from the essay

Answer 1

To show an important or unclear idea from the essay
that is important because if something is hard to explain an illustration with captions can help make sense of the passage. :)

Answer 2

To show an important or unclear idea from the essay.

Step-by-step explanation:

Images and descriptive captions can help the reader to clarify some important points that could be misunderstood when reading the essay. Illustrations contribute with the information in a visual way. All this helps the reader to understand better what was unclear. So in that way, the author is showing his work through images.
