Answer :
The type of writing is expository the inappropriate writing here is a newspaper editorial. However i don't like these types of questions because in real life people have something called "free will" so if the student REALLY wanted to share it in a newspaper editorial they probably could.

a newspaper editorial... if you're trying to directly tell your friends of your excitement, you won't put that up in a news paper... maybe social media, because yer a twit, but not a news paper
