This question was attempted by many candidates, and they did fairly well in it although few candidates wrote out of context.  In part (a), candidates gave wrong answers for what is an unbalanced diet, as “food that is not good to eat”, “food that is dangerous not balanced”.  In part (b) rather than mention one effect of adrenalin on a performing athlete candidates                                                                                                                                                                                                                                                                                                                                                                                                  wrote instead, lack of stamina, causes heart attack. In part(c), candidates wrote wrong answers for end product of fat digestion as “sweat” and “lactic acid”.
