【求助】请教三个问题

1 Assume that $A$ is a finite dimensional $K$-algebra,and $M$ a finitely generated indecomposable module, then the socle $socM $ of $M$ is simple,why?

2 Assume that $A$ is a finite dimensional $K$-algebra,and $M$ a finitely generated  module, is the injective envelope of $M$ finitely generated? why?


3 Assume that $A$ is a finite dimensional $K$-algebra,and $M$ a finitely generated indecomposable  module, is the injective envelope of $M$ indecomposable? why?
