Answer 1

Strategy pattern is used when you wish to plug algorithm or strategy at run time. As category of pattern also implies that it deals with behaviour of the objects. On the other hand bridge is structural pattern and deals with structural hierarchy of the objects. It decouples the abstraction from implementation by introducing a refined abstraction between them. Refined abstraction can be confused with the run time strategy plugged (In Strategy pattern). Bridge pattern deals with the structural aspects by providing a mechanism to avoid creating n number of classes.
