Answer to Question 1

Open clusters contain more stars, are better bound gravitationally, and will last much longer-hundreds of millions or billions of years. Associations are less massive clusters spanning a larger region of space, they are less bound, and will break up in tens of millions of years as the Galaxy spins.
