and the derived class Ostrich

Please fill the missing code so that obtain the next output:

Please don't use quotes.

Sealed method can't be overridden

True

False

Please set matches

Abstract method

Sealed method

Virtual method

Please choose the correct statements:

Abstract method can't have the 'virtual' modifier

Abstract method can't be declared in non-abstract class

Abstract method can't be overridden

Abstract method can't be sealed

Please, choose what is true about Dispose pattern:

protected virtual void Dispose(bool disposing) method should be implemented

public void Dispose() method should be implemented

It is required to implement IDisposable interface

The Dispose() method should suppress finalization

The Dispose(bool disposing) method should suppress finalization

Implementation of finalizer is not used

Which data types are inherited from System.Object?

struct

Please, choose what is true about static:

Static method can be overloaded

Static members are initialized before the static constructor, if there is one, is called.

Static method can be overriden

C# supports static local variables (variables that are declared in method scope).

Static members are initialized before the static member is accessed for the first time.

Please, choose what is true about object:

all methods of object class are virtual

object is the base type for some value types, but not all of them

A variable of object type can contain a reference to an object of an array

object is the base type for all value types

object and System.Object is the same

A variable of object type can contain a reference to an object of any other type

Which access modifiers can be applied to classes and structs that are declared directly within a namespace (in other words, that are not nested within other classes or structs)?
