ima go with the overload principle I could be wrong do
When people are stressed, anxious or feeling down, they’re not apt to make the healthy choice because they’re so overwhelmed by their situation so the correct answer here I believe is A
The answer is b. Intensity of an activity
Talk test basically determine how intense your activity is by gauging how much you can talk during that activity
For example,you can still talk while you're jogging, meanwhile you can't talk at all when you're sprinting. This means that sprinting is a far more intense activity than jogging
