Let's discard the other options first... it couldn't be kind satire, as satire refers to irony or ridicule, and the words aren't kind, they're just <u>elegant,</u> this is not the case. Borish behavior isn't possible either as it means to be rude. And finally, gross understatement isn't possible either for it refers to letting the others no some basic facts, but ignoring the magnitute of the fact. So, graceful witing means to be elegant in the words you choose as to say something; this is the case, <em>philosophic dignity </em>is the perfect example.
You study the correct way for the right answers to all problems. Sometimes we think we are right, and then findout we where wrong. Always ask questions and always double check.
