Examiners report
Many struggled with this question, not recognising it was pointing to WHO guidelines. Many also mentioned diet and other health factors not relating to exercise guidelines.
This is fairly consistent over the past few years, but some misinterpret what is meant by a risk factor and explain only consequences.
