General Adaptation Syndrome(GAS) has 3 stages: alarm, resistance, and exhaustion. In the alarm phase, you will experience an increased level of stress. At the resistance level, your body will start to adapt to the stress until the exhaustion stage come when the body too tired.
Headache and stomach ulcers are examples of the psychosomatic condition. The psychosomatic disease will start to appear at the exhaustion stage since the body had passed the capability to adapt to the stress.
I believe the correct answer is B because you obviously need to see if the person is still alive or not. I'm having second thoughts that it might be A.. I'm not sure which. Hopefully you get it right
I think this experimental method is a better option because its in a natural environment where the kids dont know whats happening unlike the suveys where you ask them questions which is probably a bad idea because they might feel scared and just change their minds.
