Puzzle Objectives

Hi!

I would like to know what is the objective to solve the puzzles?
Sometimes looks the objective is checkmate with one move, sometimes something else.

Sometimes it is to draw, sometimes win material. Or to checkmate.

But not all are checkmate in 1. Have a look at that puzzle. White checkmated black.

True, but I disagree with some moves in that puzzle

I guess should be specified if the puzzle objective is checkmate with minimum moves as possible, win material or something else.
