Answer:
appreciating the beauty of classical music is called aestheticism.
He is calling attention to the issue. President Wilson would not call the session if the topic is of policy changes and talk about going to war. He also isn't apologizing, otherwise he would use the word, "I'm sorry for calling this session." I also don't think you use "diverse" one big word in a sentence, diverse should be multiple words that aren't general. Therefore, calling attention to the issue is the most logical.
This might not be super right but it’s all I could think of but maybe like The Beatles influenced / Nsync/The Backstreet Boys/ New Edition and they influenced one direction/5sos/fifth harmony who influenced uhm maybe bts, blackpink, brockhampton, (idk too many groups this year)
i hope this helps or atleast gives you an idea or something.
