Challenge can be an important source of self-knowledge, since those who pay attention to how they react, both emotionally and physically, to challenge can gain useful insights into their own weaknesses.
Which one of the following most closely conforms to the principle above?
(A) A concert pianist should not have an entirely negative view of a memory lapse during a difficult performance. By understanding why the memory lapse occurred, the pianist can
better prepare for future performances.
(B) A salesperson should understand that the commission earned is not the only
reward of making a sale. Salespeople should also take
satisfaction from the fact that successful sales reflect well on their personalities.
(C) Compassion is valuable not only for the
wonderful feelings it brings, but also for the opportunities it affords to
enrich the lives of other people.
(D) While some of the value of competition comes from the pleasure of winning, the primary
reward of competition is competition itself.
(E) Even people who dread public speaking should accept invitations to speak before large groups. People will admire their courage and they will experience the
fulfillment of having
attempted something that is difficult for them.
Only A and E seem to make the cut. Others are wrong for the red text.
In E the difference is between 'weakness' and 'fulfillment'. The original principle is about improving while in E it is about admiration and fulfillment, there's nothing about improvement. Whether people who have already publicly spoken improved or not is not at all the point of concern. On the other hand, A gives improvement aspect by pianist being able to perform better in future.
The difficultly lies in the way the original principle is stated w.r.t. to A. Original is kind of passive in structure while A is active plain.
