Examiners report
Low-difficulty question (84.27 % correct) with a poor discrimination index. Answer A was the main distractor. G2 comments suggested this question was not specifically related to Sport, Exercise and Health Science. This has been taken on board for future paper construction. However the question was still considered to be valid.
