Matt wants to train his dog, buster, to sit on command. he gives buster a biscuit each time buster sits when commanded, but only for the first 10 trials. he then changes the rules. buster now has to sit on command three times before he gets a biscuit. in this case, matt used a schedule first, and then a schedule to train buster.

I believe the answer is: a continuous reinforcement schedule; a fixed ratio schedule of reinforcement
 a continuous reinforcement schedule refers to the process of reinforcing a desired behavior every time it occurs.
A fixed ratio schedule on the other hand , refers to the process of reinforcing a desired behavior after it occurs several time.

3. i would say one, but one is not prime nor composite.
