In a procedure called random assignment, participants are placed in experimental conditions on the basis of chance, thus minimizing biases or preexisting differences in the groups.
Basically, the experimental condition is once the man of science manipulates the variable to assess its result on the variable. Below the experimental conditions, the participants receive experimental treatment whereas the participants within the control group don't receive any treatment.
Random assignment helps make sure that members of every group within the experiment area unit identical, which implies that the teams are doubtless a lot of representative of what's present within the larger population.

Answer:
A. The words "good dog"
Explanation:
In this case, we know that the primary reinforcer is the treat. The dog is gaining an immediate reward for doing what you wanted it to do. But even after it, you also praise the dog. This praise is the secondary reinforcement. The secondary reinforcement will allow the trainer to deliver reinforcement even if the dog is not hungry, which might cause problems if you only use the primary reinforcement.
