What is considered a Hook? Are these considered hooks?

Sorry, Im new with some of the terminology that is being used on CC, but simple and quick question is
What exactly is a hook?

Based off of my observations im guessing they are EC’s? Would these be considered as hooks?

Hooks are generally standard from the university point of view:
Recruited athlete
URM (underrepresented minority)
Celebrity or child of person with international status
large donor
Legacy

and possibly: any specific need by the university:
tuba player, mural artist, junior chef, etc.

None of those are hooks. But good luck

Those are EC’S. @“aunt bea” is correct in her list of what is considered a hook.
