I honestly don't know because you haven't deigned to tell us the name of the essay nor the name of its author.

Well, the name of the essay is "Conversational Ballgames" by Nancy Masterson Sakamoto.

This doesn't match the questions.

ok I don't know the answers yet and I can't find anyone else who does, so I will give the test my best shot and then I will give you guys the correct answers (this is meant for @me because he/she really needs help, but also for others)

I did this so you guys can get a good grade ♡
