1. In the approach to anti-aliasing that was discussed the number of rays
   traced per pixel

   a. is still one ray per pixel     b. is some constant number > 1

   c. is a random number of rays


2. To generate the screen coordinates through which a ray used in
   antialising passes, it is necessary to use

   a. a single random number         b. two random numbers

   c. more than two random           d. no random numbers
      numbers

3. The x-dimension of the "box" on the screen through which the ray
   used in antialiasing passes is:

   a. world_x_size                   b. win_x_size (number of window
                                        (pixels in x dimension)

   c. win_x_size / world_x_size      d. world_x_size/win_x_size

4. Which of the following is a proper way to declare a C++ class
   named x_t

   a. typedef class x_type           b. class x_t
      {                                 {
      public:                           public:
      private:                          private:
         int x;                            int x;
      } x_t;                            } x_t;


   c. typedef class x_type           d. typedef class x_t
      {                                 {
      public:                           public:
      private:                          private:
         int x;                            int x;
      };                                };

 5. Suppose class view_t has a method named load_view() and an instance
    of the class is created as: view_t v; The proper way to invoke
    the load_view() method is:

    a.  v->load_view();               b. v.load_view();

    c. v::load_view();                d. load_view();
