Explain how images and captions can you understand the main idea.

Images create a visual representation of the text, while the caption is the text that accompanies an image, giving it meaning or clarification.

Explanation:

Much more than merely embellishing or elucidating the text, illustration can thus represent, describe, narrate, symbolize, express, play, persuade, normalize, punctuate, in addition to emphasizing its own configuration, draw attention to its support or to the visual language. It is important to note that the image rarely performs a single function, but, as with verbal language, functions are organized hierarchically in relation to a dominant function.

On the other hand, subtitles are the texts that appear immediately below or alongside (or, more rarely, above) an image, identifying it, contextualizing it and adding some information from the text that accompanies it.

i decided to stay late in the laboratory to continue my experiment with the lightbulb. at midnight, thomas edison opened the door and walked in with his head held high.

1. he leaned on the wall and observed me carefully.

2. his harsh scrutiny made me self-conscious of my skills in the lab.

3. perhaps it was just me, but the air in the laboratory began to thicken as i found myself having difficulty to breathe.

4. i turned to look at him fully as i mentally prepared myself for what my very first words would be to thomas edison.

5. the next couple of seconds shocked me. it wasn't me who spoke, but rather him and with diction i could never think of using in a simple sentence.
