<h3><u>
Explanation:</u></h3>
The project execution phase is considered as the stage three in the project management life cycle. This phase is the stage that takes more time in the development process of any project. It is this stage where the product or the service will be developed by the team will be presented to the client.
The description of the work in this execution project will be clearly understood by the scope statement of the project. It clearly describes about the list of deliverable by the projects, the constraints that are considered, key milestones and requirements. Thus, the document that can be used for the reference in the given situation will be the Scope Statement  of the project.
 
        
                    
             
        
        
        
Answer:
The correct answer is letter c. a variable-ratio scheduled.
Explanation:
Psychologist B. F. Skinner developed operant conditioning, which is a method of teaching someone a desired behavior by reinforcing that behavior either positively or negatively. A positive reinforcer happens when something is added to increase the probability of a behavior. A negative one happens when something is removed to increase the probability of a behavior. <u>
The reinforcer is presented ONLY if the subject responds with the targeted behavior, but that does not mean every time the subject responds he will receive reinforcement.</u>
<u>A variable-ratio schedule is a schedule of reinforcement in which the person is not rewarded every time. As a matter a fact, behavior is reinforced after an unpredictable number of responses.</u> Because it is unpredictable, people are often more persistent, since they know they will eventually get the reward. That is the case with Shaquille. The basket is the reinforcement of his shots, but he does not know when he will make them. So he tries harder.
