   A developer has a function that catches a specific exception, performs cleanup, and then needs to re-raise the same exception so the caller can handle it. The requirement is that the traceback must show the original raise location, not the re-raise location. Which pattern is correct?

   • Aexcept SpecificError as e: cleanup() raise e
   • Bexcept SpecificError: cleanup() raise
   • Cexcept SpecificError as e: cleanup() raise e.with_traceback(e.__traceback__)
   • Dexcept SpecificError as e: cleanup() raise SpecificError(str(e))

   What is the key difference between `__context__` and `__cause__`?

   • A`__context__` is used for explicit chaining, while `__cause__` is for implicit
   • B`__context__` is set automatically, while `__cause__` is set explicitly with `from`
   • C`__context__` contains the traceback, while `__cause__` contains the message
   • D`__context__` is always set, while `__cause__` is never set

   A developer has a function that can raise either a ValueError (for bad input) or a KeyError (for missing data). The caller wants to handle both with a single except block and log which type occurred. Which pattern is correct?

   • Aexcept ValueError or KeyError as e: log(type(e).__name__)
   • Bexcept ValueError: log("ValueError") except KeyError: log("KeyError")
   • Cexcept (ValueError, KeyError) as e: log(type(e).__name__)
   • Dexcept Exception as e: if isinstance(e, (ValueError, KeyError)): log(type(e).__name__)

   What is the role of the `__context__` attribute in exception handling?

   • AIt contains the error message as a string
   • BIt indicates whether the exception was explicitly chained
   • CIt links the current exception to the one that was being handled when it was raised
   • DIt stores the traceback of the current exception
