The second and fourth statements are opinions; opening an informational essay with such obvious bias will most likely turn away a good portion of potential readers at the get-go, making all the time and effort put into the drafting of this piece all for naught!
Although it has been quite a long time (33 years), since I was a student, at that time I was taught that one’s bias should rarely, if ever, be included in an informational essay; should one choose to do so in spite of all recommendations to the contrary, best to do so at the end of the article as deftly as possible, so as not to even alert the reader to the fact that it was done, if at all possible. The readers will not all be in agreement with you, and the point of this writing is to convey information. That cannot happen if you’ve alienated a chunk of the audience one hopes to have read this.
But, then again I may be way off base. As I said, it’s been awhile.
