I THINK the answer is d. Not 100% sure.
Answer:
Dr. Reside's experiment can not be considered effective because his study has only treatment subjects group and lack of control group. That's why his study can be very good but not valid without control group.
In his study, he concluded that 80% children after therapeutic treatment decreased the activity level which can be true but not valid without control group because when he use control group in his study then we will be able to compare the normal or control group and treatment group. Then the study will be valid and effective as well.
Well, I won't do your essay for you, but I can help outline some stuff you can change which will improve your health. Then, I'll leave it to you to explain <em>how </em>it does so! =)
So, I can't say these specifically apply to you, so I'll just make some generalised changes you can make.
<em>* begin working out</em>
<em>* eat healthier and nutritious food</em>
<em>* begin meditating </em>
<em>* cut out addictive tendencies (video games, etc)</em>
<em>* learn to love yourself (loving yourself is a key to confidence and self-forgiveness, which leads to better mental health)</em>
<em>* work on proper and consistent hygiene </em>
Hopefully, this helps! =)
