could 的逻辑反义是什么？

         BIBLE 上有道练习题，要求写出“the council member could reverse her position”的逻辑反义，答案是“the counsil member cannot reverse her position”, 为什么不是could not呢？

谢啦，看的细了忍不住就钻了

yes, it cannot be avoided.

after seeing a certain amount of questions, you may have a representative sample about Gmat problems.

Don't bother to figure out the difference.
Gmac wouldn't  test it.

Only in formal logic, you should pay attention to these tiny issues.
Gmat rarely test formal logic that is common in Lsat.

In Gmat, you need to know how to negate a statement. However, use your common sense to negate the meaning rather than rigid logical rules. Common sense is enough.
