What kind of text is this?

I am currently doing my A-Level English Language Media text, and I am hoping that this particular text is a suitable guidline, because it is the perfect style model to what I am doing. This is the kind of text I am going to write (hopefully).

The recommended texts are:
Newspaper editorial
Magazine article
Article for an online publication
Blog
Script for a radio or TV programme or podcast

I know which it can't be, but if anyone would suggest doing something else, I am open to suggestions if it is not on the recommended list. However, if it is still a suitable text, would you let me know?

I really haven't talked to my teachers much about this as they are never there, so any help would be greatly appreciated!
