Given the following incorrect program:

Which two changes make the program work correctly?

• B.  The threshold value must be increased so that the overhead of task creation does not dominate the cost of computation.
• C.  The compute () method must be changed to return an Integer result.
• D.  The myTask class must be modified to extend RecursiveAction instead of RecursiveTask
• E.  The midpoint computation must be altered so that it splits the workload in an optimal manner.
