Answer to Question 1

 Messages are how objects interact within an object-oriented context. To define a concrete class, we must provide it with exact and detailed methods so that its instances can respond to exact and unambiguous messages from other objects and provide them with its services.
 Methods are implementations of an object's public services. To ask an object to perform a service, another object must send it a message that corresponds both in substance and in form to the method that provides the service.

Answer to Question 2

D
