Why is it good practice to place an 'others' exception handler in the outermost block of a PL/SQL program unit?  
Choice 1  
 This method provides a handler to which any exceptions not handled by specific exception handlers will be propagated.  
Choice 2  
 'others' is the most inefficient exception handler and it should be placed as a last resort after all other exceptions have been handled.  
Choice 3  
 Exception handling is a bad practice in general and should be avoided.  
Choice 4  
 'others' exception handlers should be used sparingly because their definition provides the least possible information about the exceptions they trap.  
Choice 5  
 If 'others' is placed before explicitly-stated exception handlers, it will catch all exceptions and over-ride the ability of the explicit handlers to execute.
