Thanks for the question! So this question is asking us for something that would most strengthen the author’s argument concerning any modification of a film for distribution. Well, what is this argument? The author in this passage goes through a bunch of modifications and gives reasons for why they’re bad; in other words, the author is basically opposed to any modifications to films, and thinks that they’re harmful. And the examples the author uses include dubbing and subtitling, advertisements, changing the size and definition, and others. So we want to look for something that will support this idea.
Now let’s take a look at (E. Well, if (E) is true, then that means that all parts of the soundtrack contribute significantly to the film’s artistic value. So when we alter them, it damages the integrity of the film. And that helps strengthen the author’s argument that modifying films is bad, so (E) is the correct answer.
Hope this helps! Feel free to ask any other questions that you might have.
