I have done my part by offering my helping hand and have always extended it to other students in need. I have always been the helpful type, and this habit derives from personal frustration when it comes to not knowing what I need to know in order to strive for comfortability in my environment. I try to guide others and relay information that I have learned over time in hopes that it makes someone’s situation or current problem easier.
I have also been a very big advocate for equality on campus and would participate in activities that were all inclusive due to the overwhelming stresses of those who feel left out or discriminated against.
Not only would I work to make my school more enjoyable for myself, but I also work towards making it enjoyable for other’s as well.
You didn't italize or mark the phrase, but I see one good candidate:
"The circus animal trainer" is in a way another name given to Mervin, a kind of "renaming" him: this is called an appositive phrase, so if this was the phrase appositive phrase is the answer! (also, I don't see the other phrases here).
The part of this excerpt that is directed against a particular social class in Ireland is "..I grant this food will be somewhat dear, and therefore very proper for landlords, who, as they have already devoured most of the parents, seem to have the best title to the children..."
In this part Jonathan Swift criticizes powerful and rich people, mocking landlords for being a part of a high social class.
