5. If a single-level inheritance is employed and an abstract class includes some undefined methods, can the derived class also omit certain implementations?

Yes, it's always permissible

Yes, if there is only one undefined method

No, at least two methods must remain undefined

No, the derived class must provide implementations for those methods

6. Which of the following statements about single-level inheritance is incorrect?

Implementing single inheritance in a program requires exactly 2 classes

More than 2 independent classes can be part of single inheritance

11. When creating an object of a derived class in single inheritance, which constructor is invoked first?

The constructor of the base class

The constructor of the derived class

Both constructors simultaneously

A runtime error

12. If a base class includes 2 nested classes, can single-level inheritance still be applied?

Yes, it's always feasible

Yes, but only if the derived class also includes nested classes

No, this configuration involves more than 2 classes, which is incorrect

No, it's not possible
