单选题 9. TEB Attorney: TEB Corporation has been accused of not doing enough to discourage its executives from defrauding the government. This accusation is obviously false, since TEB, following its own written policy, rewards those who report the wrongdoing of others and promptly fires proven wrongdoers.
Which of the following, if true, most seriously undermines the attorney's argument in defense of TEB? ______

A、 "Wrongdoing" is defined in TEB corporate policies as "any activity by a TEB employee that defrauds TEB."
B、 TEB has instituted what it calls "customer friendly" policies of responding to every complaint customers make
C、 The government is not TEB's sole client, nor even its major client.
D、 Defrauding the government would have to involve more than one employee of any company that did so.
E、 Those who have accused TEB of not doing enough to discourage its executives from defrauding the government have themselves been government employees.

【正确答案】 A

【答案解析】 A：根据该项可知，TEB只会惩罚欺骗TEB的人，也就意味着不会惩罚欺骗政府的人，削弱结论。
B：既然会应对每一项投诉，就意味着也应对了政府的投诉，加强结论。
C：和政府是不是大客户无关，
D：和涉及雇员数量无关。
E：本文讨论的是TEB的政策和TEB有没有惩罚欺骗政府的人之间的关系，和谁起诉无关。
