What is the benefit of using the Observer pattern?*1 pointIt simplifies the communication logic between objects.It allows for dynamic relationships between objects at runtime.It promotes strong coupling between the subject and the observers.It provides a direct way to update all observers simultaneously.

In which scenario would you typically apply the Observer design pattern?*1 pointWhen you need to notify multiple objects of a change in stateWhen you need to create different objects based on a conditionWhen you need to restrict instantiation of a class to one objectWhen you need to manage access to a resource

What is the primary purpose of the Adapter pattern?*1 pointTo ensure that a class has only one instance and provide a global point of access to it.To allow for two incompatible interfaces to work together without modifying their source code.To encapsulate a group of individual factories with a common goal.To define a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.
