22.(a) What does it mean to "Shepardize" a case?

To shepardize a case means to look up a case citation to see the status of a case, parallel citations, or other use of the case in another jurisdiction. Basically, to see if something is still a "good law".

(b) What 2 things are looking to evaluate when you Shepardize a case?

(c) Why do you need to Shepardize cases you want to use in your legal argument?

(d) What are the 3 general broad categories of treatment that Shepards can provide? (Worth 9 Points)

I wanted to check my answer on the first one, but the rest I am a little confused on. When it comes to treatment I know that's like the "cert denied" or "f" is following etc, but I'm not sure what it means by broad categories.

Thank you for your help!
