Clearly there's been some kind of communication error.

很显然我们之间有些沟通问题。

Many communication errors can be corrected before they interfere with students' learning.

许多交际错误在干扰学生学习之前是可以纠正的。

But the disturbing lesson was that a slight communication error, or split-second decision by a commander, could have thwarted all their efforts; as it nearly did if not for Vasili Arkhipov's courageous choice.

细微的沟通失误或某位长官一瞬间的决定本可能使所有的努力毁于一旦；要不是瓦西里·阿尔希波夫做出了勇敢的选择，这件事就发生了。
