Question

I'm confused with all of itt

Answer 1

This is the remaining answer. All I did was search each verb definition, and place it at the rightful category. :). (If they're not correct, I apologize.) 
Walk: Stride, Trek, Shuffle, 

Talk: Roar, soliloquize

Succeed: Score

Catch: Collar, Overcome, Trap, Snare, Claw, Corral, Conquer

Answer 2

You write down the words that you could replace, and still mean the same thing, on the categories line.
