Newborn Brain Damage Researchers studied 208 infants whose brains were temporarily deprived of oxygen due to complications at birth. When researchers detected oxygen deprivation, they randomly assigned babies to either usual care or to a whole-body cooling group. The goal was to see whether reducing body temperature for three days after birth increased the rate of survival without brain damage. What is the purpose of including the "usual care" treatment in the experiment? Group of answer choices To control for the placebo effect and keep it from confounding the result To create similar treatment groups so that a cause-and-effect relationship can be established To provide a baseline for judging the survival rates of infants who received whole-body cooling
