• Question 51:

  A module can always refer to all variables declared in its parent module.

  A. True

  B. False

  Correct Answer: B

  Modules do not inherit variables from the parent module. All modules are self-contained units. So you have to explicitly define variables in the child module, and then explicit set these variables in the parent module, when you instantiate the child module.

• Question 52:
