Answer:
d. Training to relax when confronted with anxiety-arousing stimuli 
Explanation:
Systematic desensitization is a type of technique used in cognitive therapy and it is based on the principle of classical conditioning.
The goal of this technique is to remove a phobia or a stimuli that causes anxiety and substitute it with a relaxation response. 
This technique has three phases: 
- The patient is taught deep relaxation and breathing exercises. 
- The patient creates a fear hierarchy starting at stimuli that provoke the least anxiety and building up to the most fear provoking ones.
- The patient starts at the bottom of the hierarchy with the least unpleasant stimuli and practices the relaxation technique.  
The patient practices this relaxation until the stimuli doesn't provoke any anxiety and then he continues with the next stimuli in the hierarchy until he reaches the top stimuli and the anxiety is removed.
Therefore, we can say that relaxation when confronted with anxiety-arousing stimuli is a really important part of systematic desensitization.  Therefore, the correct answer is d. Training to relax when confronted with anxiety-arousing stimuli
 
        
             
        
        
        
Answer:
It is a conditional syllogism
Explanation:
It is a conditional syllogism. In a conditional system the statement goes as follows: “If A is true then B is also true”. The conclusion of a conditional syllogism is simple, and it could be inferred by the statement. In this example, the statement goes: "If I get eight hours of sleep, I will feel rested in the morning. I will sleep for eight hours tonight. Therefore, I will feel rested in the morning. "If I get eight hours of sleep” is statement A. “I will feel rested in the morning” is statement B. Consequently, if A is true then B is also true: “I will sleep for eight hours tonight. Therefore, I will feel rested in the morning”.
 
        
             
        
        
        
Hello,
The answer would be about "8-9 hours of sleep per day".
Reason:
At that age the body is growing therefore the body would need more energy to grow so thats why the amount of sleep would increase because adults, and teenagers would be into more physical activities and work that would drain his or her energy therefore they should get to 8-9 hours of sleep in order to last the person the whole day. 
If you need anymore help feel free to ask me!
Hope this helps!
