All categories have a certain level of generality associated with them.

So, for example, “to inform” might be broken up “to alert” (like tornado warning) or “to educate” (to improve understanding of an idea).

“persuade” might be: “to sell a product” or “to sell a candidate” or “to sell an idea.”

In the end, only your ability to reason matters. Not your ability to memorize categories that someone else made up.

But for purposes of a school exam, know the categories 🙂

The teacher or another student would best be able to tell you the missing ones.

That might be it. See if it rings any bells.

Inform

Entertain

Scare

Create a mystery
