Most candidates did not answer the question properly due to poor knowledge of the question.  A few that did went astray.  They failed to marshal their points but were rather sermonizing on morality and integrity of Christians.  They ought to have mentioned (i) Christian leaders were to look after the flock of Christ with tenderness (ii) They should not regard their assignment as a burden rather, they should discharge their duties willingly (iii) Not for shameful or material gain but eagerly not over bearing (iv) They should serve as true example/role model to the flocks.  In the (b) part of the question, they applied residual knowledge in stating the problems teaching Christian leaders and this paid off as it added a bit to their overall performance.
