感觉to后面太长，不如用句子好。

不对。for instance是个插入语。to allow是作为什么成分？目的状语？好像逻辑意思不符合吧？

和to bend并列？也不对。除非中间加个and来连接。

以下是引用ca3ltoys在2004-1-9 7:31:00的发言：
Growing competitive pressures may be encouraging auditors to bend the rules in favor of clients; auditors may, for instance, allow a questionable loan to remain on the books in order to maintain a bank's profits on paper.
(A) clients; auditors may, for instance, allow
(B) clients, as an instance, to allow

as for answer B, except other errors, if it's changed like the following---
clients, for instance, to allow---, do you guys think it's more plausible?

....may be encouraging auditors to bend the rules...to allow....

b改变句意

原句的意思时增长的竞争压力可能鼓励审计师按照客户的要求bend the rules比如说审计师可能任由一个有问题的贷款留在帐上....

b的意思师增长的竞争压力可能鼓励审计师按照客户的要求bend the rules并任由一个有问题的贷款留在帐上....

b中变成to bend和to allow并列

使"任由一个有问题的贷款留在帐上...."的逻辑主语变成增长的压力,逻辑不通

查了一下资料，其实很简单。as an instance不规范，应该用for instance。
