Looking Broadly Across Several Cultures, Two Important Lessons with Respect

Looking broadly across several cultures, two important lessons with respect to negotiation standout. One of those lessons is that:

A) regional generalizations very often are not correct.
B) the Japanese tend to be on the middle of the scale on almost every dimension of negotiation style.
C) national stereotypes tend to closely reflect the reality, more often than not.
D) On almost every dimension of negotiation style considered, the Japanese are on or near the end of the scale.
E) Asian negotiation styles tend to be collectively similar across all dimensions.
