The American heart association changed ABC (Airway, Breathing, Compressions) to CAB (Compressions, Airway, Breathing) because when the ABC sequence to perform CPR was performed, people would spend so much time trying to open the airway that there was a delay in chest compressions making rescue breathes harmful. With the new CAB sequence people initiate chest compressions sooner and ventilation is only slightly delayed.
Hope this helps!

Within this question, the listed tests have been put in the order of how
rigorous they are. Whilst a PAR-Q test simply involves the test
participant writing down the answers to a series of question, the other
tests included in the question all need a doctor present in order to be
performed. For example, the most rigorous test, the exercise stress
test, is only ever used when it is suspected that a patient might have a
condition that could be fatal.
