How does the Lichess Fork Challenge #6 P result in a winning position?

Hey all. Fairly new to practicing Chess and I've been working my way through the site's practice material. I was just practicing Forks and challenge #6 P says to get a winning position in 3 moves.

Well, the solution just has you exchanging pawns and a knight for a bishop. Most of the other pieces are still on the board. It really doesn't seem like an obviously winning position to me. If it is, what are some strategies for being able to tell? I spent a long time on this puzzle trying to figure out how to capture a Queen or something like that.


It's basically win a pawn: advantage is +1.2
I guess it's just so you are aware if a fork is possible, regardless of if you win material or not.

In the starting position, the knight on h5 is threatened to be trapped by g4, so the little combination, which is still available after g4, "saves" the knight. Another gain is that e5 becomes a hole, although this is a bit advanced and off topic for this practice.

Another question is: Instead of Qg3, why not Bxg5 both winning a pawn and exposing the black king?

Greek gift challenge #3 also has a problem of too many good moves.
