The use of the word "pallo-photophone" is meant to help readers understand the science behind sound films, as shown in option B.
<h3>Why is this help needed by readers?</h3>
- Because readers live in a modern age.
- Because modernity makes readers forget how technology has evolved.
- Because readers need to know where the technology came from.
The pallo-photophone was an essential creation so that we could have films with sound, where the actors speak and have greater interaction with the story and the public. Before this was not possible and although silent films were popular, talkies were much more exciting and it was through the pallo-photophone that these films could exist.
The pallo-photophone evolved over time until reaching the audio quality that movies have today. This evolution makes individuals forget how technology is a process that improves over time. For this reason, the author of the text emphasizes the pallo-photophone, to remind readers of what science was like in the past.
