Fill in the blank(s) with correct word

Answer the following statements true (T) or false (F)

1. When a base class method is overridden in a derived class, it is common to have the derived class version call the base class version and then do some additional work. 2. A base class’s method that’s overridden in a derived class will be executed implicitly when the derived class’s method is called. 3. The Protected members of a base class may be accessed in their class or any classes derived from that base class. 4. With Protected instance variables in the base class, all the derived classes of the base class may need to be modified if the base-class implementation changes. In such a case, the software is said to be non-modifiable, because a small change in the base class can “break” derived-class implementations. 5. In practice, derived classes should depend only on the base-class services (that is, Private methods and properties) and not on the base-class data implementation.
