I think its subject-by-subject comparison, hope this helps
Personally, I would phrase it like this:
The choir moved the audience to tears with their beautiful voices.
-Title/first sentence not generic
-you creative words don't start a sentence with common words
-structure- introduction, 2-3 body paragraphs, conclusion
-the introduction should introduce a question
-body paragraphs should develop a line of reasoning to answer the question
-the conclusion should summarize and the answer question.
-each paragraph should have a different point
-body paragraphs should be strongest to weakest points
Hope this is what you were looking for if you need more help message me
You are changing singular to plural. All you're doing is adding an S to the end of each underlined word.
