急!求教逻辑错误

经常在提纲上看到dilemma，这个词，这算是哪一类逻辑错误呢？应该怎样找这样的逻辑错误并反驳呢？

谢谢！

dilemma就是either-or错误。两个建议只能用A或者B。没有考虑把AB结合起来，或是其他解决方案。

7宗罪里：第五宗罪 Either-Or choice 二选一 false dilemma
The author assumes that AA and BB are mutually exclusive alternatives and there is no room for a middle ground. However, the author provides no reason for imposing an either-or choice. Common sense tells us that adjusting both AA and BB might produce better results.

谢谢,趁着MM还在,赶快再请教另一宗罪(本来昨夜想问呢,实在太困了)又出了一贴，烦请看一看。

thanks in advance
