[讨论]逻辑大全C-7

7.    Merco has been in business longer than Nolen. Inc, Olean Industries was founded years before the Potter Company, and the Potter Company was started years after the Quarles Corporation. Nolen, Inc., and the Quarles Corporation were founded in the same year.

If the information above is true, which of the following must also be true?

(A) Olean Industries has been in business for more years than Merco.

(B) Olean Industries has been in business for more years than the Quarles Corporation.

(C) Nolen, Inc., has not been in business for as many years as Olean Industries.

(D) Merco has been in business for more years than the Potter Company.（D）

(E) Nolen, Inc., has not been in business for as many years as the Potter Company.

这题E怎么错了呢？

还是不太明白呢

IN BUSINESS的时间难道不是指自从公司成立后算起吗？既然Q比P长，NI又与Q一样，那NI不就肯定比P长吗？换句话，NI与P的经营时间不一样，我的理解哪儿错了呢

请问E的意思

Nolen, Inc., has not been in business for as many years as the Potter Company

是指N和P的经营时间不一样长，还是N和P不在经营(out of business)的时间是一样长？

另外，从题目上看，感觉几家公司都正在经营之中，没有特别说明是否已经bankruptcy

appreciate more helps！！！

这个好像不难吧

Merco has been in business longer than Nolen. Inc, Olean Industries was founded years before the Potter Company, and the Potter Company was started years after the Quarles Corporation. Nolen, Inc., and the Quarles Corporation were founded in the same year.

由上可知，

M>N,O>,P<Q,Q=N

所以M>N=Q>

谢谢jeffreyqian

是我理解的问题，阅读的问题暴露出来了

Nolen, Inc., has not been in business for as many years as the Potter Company

以为指 N和P不一样长（可以大于，也可以小于），实际上正如你所说的N<

谢谢！
