Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
    int a;
    public A() {
        a = 7;
    } 
}
class B extends A {
    int b;
    public B() {
        b = 8; 
    } 
}

1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.

Answer:
class Program {
  public static void Main (string[] args) {
    double number = 1.0;
    while(number >= 0.001) {
      Console.WriteLine (number);
      number /= 2;
    }    
  }
}
Explanation:
Always think carefully about what is in the condition of the while statement. In this case, you want the loop to be executed as long as the number is larger than or equal to 0.001.
